Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when the area where the security simulation is performed is predetermined, there are cases where an intruder cannot recognize the security simulation, or it does not become a realistic security simulation, and the effect of suppressing intrusion into the building may be diminished.

[0005] An object of the present invention is to effectively suppress the intrusion of intruders into a building.

Means for Solving the Problems

[0006] One aspect of the present invention provides a security simulation system for monitoring a site area around a building, the security simulation system including a detection unit that detects a person in the site area, a determination unit that determines at least one of a plurality of building areas as a simulation area according to the detection status of the person, and a simulation unit that performs a security simulation in the determined simulation area.

[0007] The determination unit may, if the person is not detected in the site area, determine the performance area from a predetermined selection of building areas among the multiple building areas, or, if the person is detected, determine the performance area from all of the multiple building areas.

[0008] If the person is not detected in the site area, the determination unit may determine the building area visible from outside the site area among the multiple building areas as the performance area. If the person is detected, the performance area may be determined from all of the multiple building areas according to the position of the detected person.

[0009] The determination unit may, when it detects a person in the site area, determine the performance area based on the relationship between the location of the detected person and the location of each of the multiple building areas.

[0010] The security system further includes a storage unit that stores area information relating each location within the site area to one or more building areas visible from each location, and the determination unit may, when a person is detected, determine the building area corresponding to the location where the person was detected as the security area based on the area information.

[0011] The security system further comprises a determination unit that determines whether a person is present inside the building, and the determination unit may, when no person is detected in the site area, determine a building area visible from outside the site area among the multiple building areas as the security area if the person is absent, and when the person is present, determine a building area visible from outside the site area where no person is present as the security area.

[0012] The security system includes a setting unit that sets one of several security modes for monitoring intrusion into the building, and a monitoring unit that monitors intrusion attempts into the multiple building areas based on the set security mode. The determination unit may, if no person is detected in the site area, determine the performance area from a building area visible from outside the site area according to the set security mode.

[0013] The security mode can be set to at least one alert mode or deactivation mode for each building area, and if no person is detected in the site area, the determination unit may determine the building area that is set to the alert mode among the building areas visible from outside the site area as the performance area.

[0014] The performance unit includes a projection unit that projects an image representing the presence of a resident in the determined performance area, and the projection unit may change the content of the projected image depending on whether the person is detected in the site area or not.

Mode for Carrying Out the Invention

[0017] 1. Configuration FIG. 1 is a diagram showing an example of the configuration of a monitoring system 10 according to an embodiment. The monitoring system 10 provides a monitoring service for monitoring a monitoring area 20. The monitoring area 20 consists of the indoor area of a building 21 and the outdoor area around the building 21. The building 21 is a house for personal residence, such as a single-family house or an apartment. The outdoor area around the building 21 is the external space of the building 21 within the site of the building 21. For example, in the case of a single-family house, it is a garden, and in the case of an apartment, it is a balcony. The monitoring system 10 detects a person who has entered the monitoring area 20 (hereinafter referred to as an "intruder") and reports it to the monitoring center. In addition, the monitoring system 10 performs a security effect on the building 21 in order to suppress the intrusion of the intruder into the indoor area of the building 21. The monitoring system 10 is an example of a security effect system according to the present invention.

[0018] FIG. 2 is a diagram showing an example of the monitoring area 20. The monitoring area 20 includes the inside of the building 21 and the outside within the site of the building 21 (hereinafter also referred to as the "outdoor monitoring area"). The outdoor monitoring area is an example of the site area around the building according to the present invention. In the outdoor monitoring area, a range within a predetermined distance or less from the building 21 is set as the proximity range 22. In FIG. 2, a plan view of the second floor of the building 21 is shown. There are four rooms R1 to R4 on the second floor of the building 21. Windows W1 to W4 are provided in the rooms R1 to R4, respectively. Among these windows W1 to W4, the windows W1 and W2 face the road adjacent to the monitoring area 20. This road may include a sidewalk and a driveway. On the other hand, the windows W3 and W4 face the site of the adjacent building through, for example, the back yard and do not face the road. Also, the building 21 is not limited to the second floor, and other floors may also be provided with rooms and windows. In addition, in order not to determine a person who has legitimately entered the site, such as a resident or a delivery person, as an intruder, the approach portion from the door to the entrance door may be excluded from the monitoring area. Alternatively, the approach portion may be set as a monitoring area that allows temporary stay.

[0019] Returning to FIG. 1, the monitoring system 10 includes a plurality of intrusion monitoring sensors 100, a controller 2, a monitoring device 300, a server device 400, a plurality of projection devices 500, and a plurality of speakers 600. A part of the plurality of intrusion monitoring sensors 100, the controller 200, the monitoring device 300, and the plurality of projection devices 500 are installed inside the building 21. The other intrusion monitoring sensors 100 and the plurality of speakers 600 are installed outside the building 21. The plurality of intrusion monitoring sensors 100, the controller 200, the monitoring device 300, the plurality of projection devices 500, and the plurality of speakers 600 are connected via a communication network 11 such as a LAN (Local Area Network).

[0020] The server device 400 is installed in a monitoring center operated by a business operator that provides a monitoring service. The controller 200 and the server device 400 are connected via a communication network 12 such as the Internet.

[0021] The intrusion monitoring sensor 100 detects intruders entering the monitoring area 20 and outputs detection information. The intrusion monitoring sensor 100 is an example of a detection unit according to the present invention. The intrusion monitoring sensor 100 includes an intrusion monitoring sensor 100 installed indoors of the building 21 and an intrusion monitoring sensor 100 installed outdoors of the building 21. The indoor intrusion monitoring sensor 100 is installed, for example, in openings such as entrance doors and windows, in areas of traffic such as corridors within the residence, and in living rooms. The outdoor intrusion monitoring sensor 100 is installed, for example, on the exterior wall of the building 21, in the garden, on the balcony, on the gate, on the fence, etc. In the example shown in Figure 2, the intrusion monitoring sensor 100A is installed outside the outdoor proximity range 22, and the intrusion monitoring sensor 100B is installed inside the outdoor proximity range 22. The intrusion monitoring sensor 100A monitors monitoring area A, which is the area around window W3 of room R3, and the intrusion monitoring sensor 100B monitors monitoring area B, which is the area around window W3 of room R3. In reality, intrusion monitoring sensors 100 are installed in addition to intrusion monitoring sensors 100A and 100B, but to avoid making the diagram too complex, Figure 2 omits the illustration of intrusion monitoring sensors 100 other than 100A and 100B.

[0022] The intrusion monitoring sensor 100 includes, for example, window / door sensors, motion sensors, image sensors, and lighting / appliance operation detection sensors. Window / door sensors are installed in openings such as front doors, windows, and gates to detect the opening of doors and windows. Examples of window / door sensors include sensors that detect door opening by detecting changes in the magnetic field, and sensors that detect door opening by turning a tamper switch on or off. Motion sensors, also called spatial sensors, are installed in areas with high traffic or in living spaces to detect the presence of people. Examples of motion sensors include pyroelectric infrared sensors that detect fluctuations in heat rays emitted by the human body, ultrasonic sensors and radio wave sensors (such as those using millimeter waves or microwaves) that detect moving objects, laser scanning distance sensors that detect the distance and direction to an object, and infrared sensors that detect the blockage of infrared rays between transmitters and receivers. Image sensors detect intruders by comparing images of the monitored space with reference images, or by using a trained AI model. Lighting / appliance operation detection sensors may be installed on appliances and detect operations performed using the appliance's operation buttons. Alternatively, lighting / appliance operation detection sensors may be installed in a location where they can receive operation signals transmitted from a remote controller to the appliance, and detect operations on the appliance based on these operation signals. Examples of appliances include television receivers, lighting fixtures, air conditioners, heaters, fans, electric kettles, radios, water, gas, and electricity. For example, if operation of a television is detected, it is possible to detect that a resident is in the location where the television is installed (e.g., the living room).

[0023] For intrusion monitoring sensors 100 installed outdoors, motion sensors and image sensors are suitable. Scanning laser sensors and image sensors are suitable for monitoring outdoor premises because a single sensor can identify the location of a person within the monitoring area.

[0024] The controller 200 controls multiple intrusion monitoring sensors 100, a monitoring device 300, multiple projection devices 500, and multiple speakers 600. The controller 200 also monitors for intrusion into the monitoring area 20 using the intrusion monitoring sensors 100 based on the security mode. The controller 200 is an example of a monitoring unit according to the present invention. For example, when an intruder is detected by the intrusion monitoring sensor 100, the controller 200 notifies the server device 400 that an intruder has entered the monitoring area 20. The controller 200 has three security modes: alert mode, partial alert mode, and deactivation mode.

[0025] The alert mode is a security mode that monitors the entire monitoring area 20. The alert mode is used when residents are out and the monitoring area 20 is unoccupied. In alert mode, when detection information is output from the intrusion monitoring sensor 100, an abnormality signal is sent from the controller 200 to the server device 400. When the alert mode is set, the indoor and outdoor intrusion monitoring sensors 100 that monitor the resident's exit route (including the approach area) will start detecting intruders after a predetermined time has elapsed to prevent false detection of residents leaving the building as intruders. In addition, since the aforementioned approach area allows for temporary stays by residents returning home or visitors such as delivery personnel, the indoor and outdoor intrusion monitoring sensors 100 that monitor the entrance route (including the approach area) will output detection information if they have detected a person for a predetermined period of time or longer.

[0026] Partial security mode is a security mode that monitors a portion of the monitoring area 20. Partial security mode is used when there are residents in the monitoring area 20 and it is necessary to monitor for intruders in areas where there are no residents. For example, in partial security mode, predetermined outer areas such as the front door, windows, gates, and the outside of the residence are monitored to detect intrusion into the monitoring area 20 from the outside. Alternatively, from among multiple areas included in the monitoring area 20, areas set as monitoring targets according to the user's operation may be monitored. In this way, in partial security mode, a security mode or deactivation mode can be set for each area of ​​the building 21. In partial security mode, when detection information is output from an intrusion monitoring sensor 100 installed in the outer area or a designated area (such as the second floor), an abnormality signal is sent from the controller 200 to the server device 400. On the other hand, even if detection information is output from an intrusion monitoring sensor 100 installed in a location other than the outer area or a designated area, this detection information is ignored, and no abnormality signal is sent from the controller 200 to the server device 400.

[0027] The deactivation mode is a security mode in which the monitoring area 20 is not monitored. The deactivation mode is used when there is a user in the monitoring area 20 and there is no need to monitor for intruders. In deactivation mode, intruders into the monitoring area 20 are not monitored, and even if detection information is output from the intrusion monitoring sensor 100, this detection information is ignored, and no abnormal signal is sent from the controller 200 to the server device 400.

[0028] The monitoring device 300 is installed, for example, in the entrance or living room of building 21 and is used to set the security mode. The monitoring device 300 receives an operation to set the security mode of the controller 200. Upon receiving this operation, the monitoring device 300 transmits the security mode setting information to the controller 200.

[0029] When the server device 400 receives an abnormal signal from the controller 200, it outputs information about the monitoring area 20, prompting the control operator of the monitoring sensor to take action regarding the security guards rushing to the monitoring area 20.

[0030] The projection device 500 projects an image for security purposes onto at least one of several areas in the building 21. The projection device 500 is an example of a display unit or projection unit according to the present invention. Each of the multiple projection devices 500 is installed in a position where it can project images onto several areas inside the building 21. These areas are, for example, the windows of the building 21. In the example shown in Figure 2, projection devices 500A to 500D are installed in positions where they can project images onto windows W1 to W4 of the building 21. The images projected by the projection device 500 include holograms, moving images, still images, photographs, and text. The projection device 500 is, for example, a projector, and projects images such as human figures that simulate the presence of people into rooms onto transparent screens provided in several areas of the building 21. The projection device 500 stores image data that represents an image in advance and projects an image corresponding to the image data onto the transparent screen. By projecting an image onto the transparent screen, the projected image can be viewed from the outside of the building 21 from inside the building 21. The medium on which the projection device 500 projects images is not limited to a transparent screen; it may also be a transparent curtain, a window with a film that can project images onto it, an indoor space, or an exterior wall. When projecting a 3D hologram, the projection device 500 projects the 3D hologram towards the indoor space.

[0031] Speaker 600 outputs security sound corresponding to the security image projected onto the area of ​​building 21. Speaker 600 is an example of a security system according to the present invention. Multiple speakers 600 are arranged so that the sound can be heard at any location outside building 21. In the example shown in Figure 2, speaker 600A is installed in front of building 21, and speaker 600B is installed in the back of building 21. Speaker 600 has pre-stored audio data indicating alarm sounds. Speaker 600 outputs alarm sounds corresponding to the audio data.

[0032] Figure 3 shows an example of the configuration of the controller 200. The controller 200 comprises a control unit 201, a storage unit 202, and a communication unit 203. The various parts of the controller 200 are connected via a bus.

[0033] The control unit 201 controls each part of the controller 200 and performs various processes. For example, the control unit 201 includes a CPU (Central Processing Unit). The storage unit 202 stores programs and various data for realizing the functions of the controller 200. For example, the storage unit 202 includes memory such as ROM (Read Only Memory) and RAM (Random Access Memory), and storage such as HDD (Hard Disk Drive) and SSD (Solid State Drive). The communication unit 203 is a communication interface for connecting the controller 200 to the communication networks 11 and 12. The communication unit 203 is used to communicate with other devices connected via the communication networks 11 or 12.

[0034] The control unit 201 functions as an acquisition unit 211, a setting unit 212, a determination unit 213, a specific unit 214, and a performance control unit 215. These functions are realized when the control unit 201 executes a program stored in the storage unit 202, performs calculations, or controls each part of the controller 200.

[0035] When the intrusion monitoring sensor 100 detects an intruder, the acquisition unit 211 acquires the detection information output from the intrusion monitoring sensor 100. In addition, when an operation to set the security mode is performed using the monitoring device 300, the acquisition unit 211 acquires the security mode setting information from the monitoring device 300.

[0036] The setting unit 212 sets one of several security modes. These security modes include the alert mode, partial alert mode, and deactivation mode described above. When an operation to set a security mode is performed using the monitoring device 300, the setting unit 212 sets the security mode according to the setting information acquired by the acquisition unit 211.

[0037] The determination unit 213 determines, based on the detection status of intruders in the outdoor monitoring area by the intrusion monitoring sensor 100, to be an area where security effects will be applied to at least one of several areas of the building 21 that are visible from the outside. The multiple areas are, for example, the windows of the building 21. The multiple areas of the building 21 are an example of multiple building areas according to the present invention. The windows of the building 21 are an example of an effect area according to the present invention.

[0038] Figure 4 illustrates an example of a method for determining the area to be equipped with security measures. If no intruder is detected in the outdoor monitoring area by the intrusion monitoring sensor 100, the determination unit 213 determines the area to be equipped with security measures according to the security mode set by the setting unit 212.

[0039] For example, when the setting unit 212 is set to alert mode, the determination unit 213 determines that the area visible from the road surrounding the monitoring area 20 will be the area to which security effects will be applied. More specifically, the area visible from the road is the area visible to road users, for example, the area facing the road. The area visible from the road is a part of several areas of the building 21 and is predetermined. In alert mode, all areas of the building 21 are set as monitoring targets, so the area visible from the road is also set as a monitoring target. Since the road is outside the building 21 site, the area visible from the road is an example of a building area visible from outside the site area according to the present invention. Note that when the setting unit 212 is set to alert mode, areas that are difficult to see from the road surrounding the monitoring area 20 are not determined to be the area to which security effects will be applied. In the example shown in Figure 2, the determination unit 213 determines windows W1 and W2 that face the road. In reality, the windows on the first floor of building 21 facing the road will also be determined, but to avoid making the explanation too complicated, the explanation of the first floor of building 21 will be omitted. Before an intruder enters building 21 without permission and commits a crime such as theft, they may observe the inside of building 21 from the road. By installing security measures in areas visible from the road, it is possible to deter such crimes from occurring.

[0040] For example, if the deactivation mode is set by the setting unit 212, the determination unit 213 determines areas where no residents are present as areas where security effects will be applied. Areas where no residents are present are identified, for example, based on detection information output from the indoor intrusion monitoring sensor 100. However, even among areas where no residents are present, the determination unit 213 sets a higher priority for areas visible from the road than for other areas. Furthermore, based on the detection history of the indoor intrusion monitoring sensor 100, the determination unit 213 may also set a higher priority for areas where residents do not normally enter, even among areas where no residents are present, than for other areas. In the example shown in Figure 2, if a resident is in room R1, the determination unit 213 determines windows W2 to W4 in rooms R2 to R4 where no residents are present. The determination unit 213 also sets a higher priority for window W2, which faces the road, among these windows W2 to W4, than for windows W3 and W4, which do not face the road. In reality, windows in rooms on the first floor of Building 21 that are not occupied will also be determined, but to avoid making the explanation complicated, the explanation of the first floor of Building 21 will be omitted. A recent crime trend is that, for example, even when residents are inside Building 21, perpetrators enter areas where no residents are present and commit theft. By installing security measures in areas where no residents are present, such crimes can be prevented.

[0041] For example, if the setting unit 212 has set a partial security mode, the determination unit 213 determines the area set as the target of monitoring in the partial security mode as the area to which security effects will be applied. The area set as the target of monitoring in the partial security mode is identified, for example, based on the setting information of the security mode. However, among the areas set as the target of monitoring, the determination unit 213 sets the priority of the area visible from the road higher than the priority of the other areas. In the example shown in Figure 2, if the resident is on the first floor (not shown) of building 21, and the second floor of building 21 is set as the target of monitoring in the partial security mode, the determination unit 213 determines windows W1 to W4 on the second floor. Furthermore, among the windows W1 to W4 on the second floor set as the target of monitoring, the determination unit 213 sets the priority of windows W1 and W2 facing the road higher than the priority of windows W3 and W4 not facing the road. If the second floor of building 21 is set as the target of monitoring in the partial security mode, there are no residents on the second floor of building 21. However, a recent crime trend involves cases where, for example, thieves break into the second floor of a building where residents are present, even though the second floor is unoccupied, and commit theft. By implementing security measures in the areas designated as monitored in partial security mode, such crimes can be prevented.

[0042] On the other hand, if an intruder is detected in the outdoor monitoring area by the intrusion monitoring sensor 100, the decision unit 213 determines the area visible from the intruder's location from among multiple areas of the building 21 as the area to be enhanced with security measures. The intruder's location may be measured by the intrusion monitoring sensor 100, or the detection range of the intrusion monitoring sensor 100 may be considered as the intruder's location. The area visible from the intruder's location may be an area visible from the road, or an area that is difficult to see from the road. The reason why an area difficult to see from the road is included in the area visible from the intruder's location is that there is a possibility that the intruder may enter from a place other than the road, such as a backyard. The decision unit 213 determines the area visible from the intruder's location based on the area table 221 that is pre-stored in the storage unit 202.

[0043] Figure 5 shows an example of an area table 221. The area table 221 shows the positional relationship between the location of an intruder detected by each outdoor intrusion monitoring sensor 100 and the location of each window of the building 21. The area table 221 is an example of area information according to the present invention. The area table 221 stores sensor IDs, window IDs, and distance information. The sensor ID is information that uniquely identifies the outdoor intrusion monitoring sensor 100. The window ID is information that uniquely identifies the window of the building 21. The distance information indicates whether the distance from the building 21 to the intruder is within or outside the proximity range 22. In the area table 221, the sensor ID of each outdoor intrusion monitoring sensor 100 is associated with the window ID of the window visible from the location of the intruder detected by that intrusion monitoring sensor 100, and the distance information indicating whether the distance from the building 21 to the intruder detected by that intrusion monitoring sensor 100 is within or outside the proximity range 22. Furthermore, if multiple windows are visible from the location of the intruder detected by the intrusion monitoring sensor 100, the sensor ID of the intrusion monitoring sensor 100 may be associated only with the window ID of the window closest to the sensor 100, or it may be associated with the window IDs of all of those windows.

[0044] The identification unit 214 identifies the content of the security effect to be applied to the area determined by the decision unit 213, according to the intruder detection status by the intrusion monitoring sensor 100. In this embodiment, the security effect includes image projection and sound output. The identification unit 214 differentiates the content of the projected image depending on whether an intruder is detected in the outdoor monitoring area by the intrusion monitoring sensor 100 or not. For example, if no intruder is detected in the outdoor monitoring area by the intrusion monitoring sensor 100, the identification unit 214 identifies a first image for the "home occupancy" effect.

[0045] The first image used to create the illusion of occupancy is an image intended to give the impression that the residents are at home in building 21. Preferably, the first image used to create the illusion of occupancy is a video showing the residents' daily life, including one or more human figures. For example, it may include a video of a family sitting together or a video of a person moving around inside a room. Furthermore, the first image used to create the illusion of occupancy, which is projected at night, may also include curtains to make it difficult to see inside from the outside. By projecting the first image used to create the illusion of occupancy, it is possible to make intruders who are scouting building 21 realize that the residents are at home, prevent them from realizing the times when the residents are away, and thus deter them from considering the building as a potential burglary target.

[0046] On the other hand, if an intruder is detected in the outdoor monitoring area by the intrusion monitoring sensor 100, the identification unit 214 will change the content of the projected image depending on the distance between the intruder and the building 21. For example, if the distance from the building 21 to the intruder is outside the proximity range 22, the identification unit 214 will identify a second image for faking occupancy, which will pretend that the occupants of the building 21 are at home and that the occupants have noticed the intrusion. On the other hand, if the distance from the building 21 to the intruder is within the proximity range 22, the identification unit 214 will identify a deterrent image. In addition, the system may also identify an audio for faking occupancy and a deterrent audio.

[0047] The second image used to create the illusion of occupancy is intended to deter intruders from entering the building. Preferably, the second image is a video showing a resident being vigilant against an intruder. For example, the second image may include a video of a resident facing a window and looking outside. Alternatively, the second image may include a video of a dog barking. Furthermore, the second image projected at night may include curtains to make it difficult to see inside from the outside. By projecting the second image, an intruder who has entered the premises of building 21 may be made to believe that they are being discovered by the resident, causing them to hesitate to continue their intrusion and ultimately abandon their attempt.

[0048] The deterrent image is intended to inform intruders that the surveillance system 10 is active and to strongly urge them to leave. The deterrent image may include text such as "On alert. Leave immediately." This is because, when viewed from the proximity range 22, it becomes clear that the projected image from the projection device 500 does not actually exist. Therefore, it is thought that informing intruders that the surveillance system 10 is active will deter them from attempting to intrude and prevent damage to the building 21. Furthermore, even if the deterrent image does not completely prevent intrusion, if it can make them hesitate, it will buy time until security personnel arrive on the scene.

[0049] The performance control unit 215 controls the projection device 500 or speaker 600 corresponding to the area determined by the determination unit 213 to apply the security effect specified by the identification unit 214 to this area. If an image is specified by the identification unit 214, the performance control unit 215 transmits a control signal to the projection device 500 to project this image. If sound is specified by the identification unit 214, the performance control unit 215 transmits a control signal to the speaker 600 to output this sound. Based on the performance device table 222 pre-stored in the storage unit 202, the performance control unit 215 identifies the projection device 500 or speaker 600 corresponding to the area determined by the determination unit 213.

[0050] Figure 6 shows an example of the performance equipment table 222. The performance equipment table 222 stores window IDs, projection device IDs, and speaker IDs. The window ID is information that uniquely identifies a window in building 21. The projection device ID is information that uniquely identifies the projection device 500. The speaker ID is information that uniquely identifies the speaker 600. In the performance equipment table 222, the window ID of each window is associated with the projection device ID of the projection device 500 that projects an image onto that window, and the speaker ID of the speaker 600 that emits sound that reaches the position of an intruder who can see the window.

[0051] Furthermore, if multiple areas are determined by the determination unit 213, the performance control unit 215 may control multiple projection devices 500 or multiple speakers 600 corresponding to these areas to apply security effects to each area at different timings. The order and timing of the security effects applied by these projection devices 500 or speakers 600 may be predetermined, determined randomly, or determined by the resident's life cycle inferred from the detection history of the indoor intrusion monitoring sensor 100. For example, when the performance control unit 215 projects the first home presence image to multiple areas, it may change the area to which the first home presence image is projected at predetermined time intervals, such as every 30 minutes. The performance control unit 215 may also change the time interval at which the area to which the first home presence image is projected is changed. Furthermore, considering that in daily life there may be times when the resident is not in any of the multiple areas, such as when going to the toilet, the performance control unit 215 may set a time, such as 10 minutes, during which the first home presence image is not projected. Furthermore, the performance control unit 215 may determine a first image to display for the "at-home" effect according to the family composition residing in the building 21. For example, in the case of a family of four, the number of people appearing in a single image will be limited to a maximum of four. In addition, if the deactivation mode or partial alert mode is set, the unit will select and display an image in which the number of people detected inside the building 21 and the number of people appearing in the image do not exceed the number of people in the family composition. Note that if all family members are in a designated area such as the living room of the building 21, an image of an animal such as a dog may be displayed in another area instead of a person.

[0052] Furthermore, if a priority is set when multiple areas are determined by the determination unit 213, the performance control unit 215 may apply the security effects according to this priority. For example, the performance control unit 215 may control only the projection device 500 or speaker 600 corresponding to the area with the highest priority among the multiple areas determined by the determination unit 213, and apply the security effects only to the area with the highest priority. In another example, the performance control unit 215 may control each of the multiple projection devices 500 or multiple speakers 600 corresponding to the multiple areas determined by the determination unit 213, and apply the security effects to all of these areas at different timings. However, the performance control unit 215 may make the time spent applying the security effects to the high-priority area longer than the time spent applying the security effects to the low-priority area, or make the frequency of applying the security effects to the high-priority area higher than the frequency of applying the security effects to the low-priority area.

[0053] 2.Operation Figures 7-9 are sequence charts showing an example of security system processing. When the intrusion monitoring sensor 100 does not detect an intruder in the outdoor monitoring area, the process in step S11 is started. In step S11, the determination unit 213 of the controller 200 determines an area corresponding to the security mode set by the setting unit 212. As shown in Figure 4, for example, if the security mode set by the setting unit 212 is the alert mode, the determination unit 213 determines an area visible from the road. In the example shown in Figure 2, the area visible from the road is windows W1 and W2 facing the road, so the determination unit 213 determines windows W1 and W2.

[0054] For example, if the security mode set by the setting unit 212 is the deactivation mode, the determination unit 213 determines the areas where there are no residents, as shown in Figure 4. In the example shown in Figure 2, the resident is in room R1, so the determination unit 213 determines the windows W2 to W4 in rooms R2 to R4 where there are no residents. The determination unit 213 also sets the priority of window W2, which faces the road, to be higher than the priority of windows W3 and W4, which do not face the road.

[0055] For example, if the security mode set by the setting unit 212 is the partial security mode, the determination unit 213 determines the area set as the target of monitoring, as shown in Figure 4. In the example shown in Figure 2, if the target of monitoring is set to the second floor in partial security mode, the determination unit 213 determines the windows W1 to W4 on the second floor. The determination unit 213 also sets the priority of windows W1 and W2, which face the road, to be higher than the priority of windows W3 and W4, which do not face the road.

[0056] In step S12, the identification unit 214 of the controller 200 identifies the first image for home viewing.

[0057] In step S13, the performance control unit 215 of the controller 200 transmits a control signal to the projection device 500, which projects an image onto the area determined in step S11, for projecting the first home performance image identified in step S12.

[0058] Here, we will explain using the case where windows W1 and W2 are determined in step S11 as an example. In the projection device table 222 shown in Figure 6, the window ID of window W1 is associated with the projection device ID of projection device 500A, and the window ID of window W2 is associated with the projection device ID of projection device 500B. This indicates that projection device 500A is the entity that projects images onto window W1, and projection device 500B is the entity that projects images onto window W2. In this case, the projection control unit 215 identifies projection devices 500A and 500B. The projection control unit 215 then transmits control signals to projection devices 500A and 500B to project the first home presence image at different timings. The order and timing of projection by projection devices 500A and 500B to project the first home presence image may be predetermined, determined randomly, or determined by the resident's lifecycle inferred from the detection history of the indoor intrusion monitoring sensor 100.

[0059] In step S14, when the projection device 500 receives a control signal from the controller 200, it projects a first image for facilitating the appearance of a resident inside the building 21 in accordance with this control signal. For example, projection device 500A projects a first image for facilitating the appearance of a resident inside the building 21, including the silhouette of a person going about their daily life, onto a transparent screen installed in window W1 for 30 minutes. Subsequently, projection device 500B projects a first image for facilitating the appearance of a resident inside the building 21, including the silhouette of a person going about their daily life, onto a transparent screen installed in window W2 for 30 minutes. Projection devices 500A and 500B repeat this operation. Since the first image for facilitating the appearance of a resident inside the building 21 is projected onto windows W1 and W2, which are visible from the road, it appears to people using the road that the residents are inside the building 21.

[0060] In step S15, the determination unit 213 of the controller 200 determines whether or not an intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100. If the acquisition unit 211 of the controller 200 has not received detection information from the outdoor intrusion monitoring sensor 100, the determination unit 213 determines that no intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100 (the determination in step S15 is NO). In this case, the process returns to step S11 as described above, and the processing from step S11 onwards is carried out. If the security mode is changed, the processing in steps S11 to S14 is carried out based on the changed security mode. On the other hand, if an intruder is detected by the outdoor intrusion monitoring sensor 100 and the acquisition unit 211 of the controller 200 receives detection information from that intrusion monitoring sensor 100, the determination unit 213 determines that an intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100 (the determination in step S15 is YES). If it is determined that an intruder has been detected, the process proceeds to step S21 shown in Figure 8.

[0061] In step S21, the determination unit 213 of the controller 200 determines the area visible from the location of the intruder detected by the intrusion monitoring sensor 100. Here, we will explain using the case where an intruder is detected by the intrusion monitoring sensor 100A as an example. In the area table 221 shown in Figure 5, the sensor ID of the intrusion monitoring sensor 100A is associated with the window ID of window W3. This indicates that window W3 is visible from the location of the intruder detected by the intrusion monitoring sensor 100A. Therefore, the determination unit 213 determines window W3.

[0062] In step S22, the identification unit 214 of the controller 200 determines whether the distance from the building 21 to the intruder is within the proximity range 22. In the area table 221 shown in Figure 5, the sensor ID of the intrusion monitoring sensor 100A is associated with distance information that is "outside the proximity range". This indicates that the distance from the building 21 to the intruder detected by the intrusion monitoring sensor 100A is outside the proximity range 22. Therefore, the identification unit 214 determines that the distance from the building 21 to the intruder is outside the proximity range 22. If it is determined that the distance from the building 21 to the intruder is outside the proximity range 22 (the determination in step S22 is NO), the process proceeds to step S23.

[0063] In step S23, the identification unit 214 of the controller 200 identifies a second home-visit image as the image to be projected onto the area determined in step S21.

[0064] In step S24, the performance control unit 215 of the controller 200 transmits a control signal to the projection device 500, which projects an image onto the area determined in step S21, for projecting the second home performance image identified in step S23. Here, we will explain using the case where window W3 is determined in step S21 as an example. In the performance device table 222 shown in Figure 6, the window ID of window W3 and the projection device ID of projection device 500C are associated. This indicates that the projection device 500C is the entity that projects the image onto window W3. In this case, the performance control unit 215 identifies the projection device 500C. The performance control unit 215 then transmits a control signal to the projection device 500C for projecting the second home performance image.

[0065] In step S25, when the projection device 500 receives a control signal from the controller 200, it projects a second image for creating the illusion of someone being at home, corresponding to the second image data for creating the illusion of someone being at home, in accordance with this control signal. For example, the projection device 500C projects a second image for creating the illusion of someone being at home onto a transparent screen installed in the window W3, which includes an image of a person looking out the window. Since the second image for creating the illusion of someone being at home is projected onto the window W3, which is visible from the intruder's position, the intruder appears to face risks such as being spotted by the residents of the building 21.

[0066] In step S26, the performance control unit 215 of the controller 200 transmits a control signal to speaker 600, which outputs sound that reaches the location of the intruder detected by the intrusion monitoring sensor 100, to output an alarm sound corresponding to the second home-visit performance image identified in step S23. For example, the alarm sound may include the sound of a dog barking and be linked to a video showing a person reacting to the sound by looking outside. In the performance device table 222 shown in Figure 6, the window ID of window W3 is associated with the speaker ID of speaker 600B. This indicates that speaker 600B is the entity that outputs sound that reaches the location of an intruder who can see window W3. In this case, the performance control unit 215 identifies speaker 600B. The performance control unit 215 then transmits a control signal to speaker 600B to output the alarm sound.

[0067] In step S27, when speaker 600 receives a control signal from controller 200, it outputs a warning sound corresponding to the audio data according to this control signal. For example, speaker 600B outputs a warning sound that includes the sound of a dog barking. Since the warning sound is output from speaker 600B, which can reach the intruder's location, it can strongly make the intruder feel that there is a risk, such as the presence of a dog in building 21. In addition, since loud noises attract the attention of nearby residents, outputting a warning sound can make the intruder hesitate to continue their intrusion.

[0068] In step S28, the determination unit 213 of the controller 200 determines whether or not an intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100. If the acquisition unit 211 of the controller 200 has not received detection information from the outdoor intrusion monitoring sensor 100, the determination unit 213 determines that no intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100 (the determination in step S28 is NO). In this case, the process returns to step S11 shown in Figure 7, and the processes from step S11 onwards are carried out. On the other hand, if an intruder is detected by the outdoor intrusion monitoring sensor 100 and the acquisition unit 211 of the controller 200 receives detection information from that intrusion monitoring sensor 100, the determination unit 213 determines that an intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100. If it is determined that an intruder has been detected in the outdoor monitoring area by the intrusion monitoring sensor 100 (the determination in step S28 is YES), the process returns to step S21 as described above, and the processes from step S21 onwards are carried out.

[0069] In the example shown in Figure 2, when the intruder moves closer to the building 21 and is detected by the intrusion monitoring sensor 100B, the process returns to step S21 described above. In the area table 221 shown in Figure 5, the sensor ID of the intrusion monitoring sensor 100B is associated with the window ID of window W3. Therefore, when the intrusion monitoring sensor 100B detects an intruder, in step S21, the determination unit 213 of the controller 200 determines which window W3 is visible from the intruder's position. Also in Figure 5, the area table 221 associates the sensor ID of the intrusion monitoring sensor 100B with distance information, "within proximity range". Therefore, in step S22, the identification unit 214 of the controller 200 determines that the distance from the building 21 to the intruder is within proximity range 22. If it is determined that the distance from building 21 to the intruder is within the proximity range 22 (the determination in step S22 is YES), it is considered that the intruder intends to enter the interior of building 21, and the process proceeds to step S31 shown in Figure 9.

[0070] In step S31, the identification unit 214 of the controller 200 identifies a deterrent image to be projected onto the area determined in step S21.

[0071] In step S32, the performance control unit 215 of the controller 200 transmits a control signal to the projection device 500, which projects an image onto the area determined in step S21, for projecting the intimidation image identified in step S31. Here, we will explain using the case where window W3 is determined in step S21 as an example. In the performance device table 222 shown in Figure 6, the window ID of window W3 and the projection device ID of projection device 500C are associated. This indicates that the projection device 500C is the entity that projects the image onto window W3. In this case, the performance control unit 215 identifies the projection device 500C. The performance control unit 215 then transmits a control signal to the projection device 500C for projecting the intimidation image.

[0072] In step S33, when the projection device 500 receives a control signal from the controller 200, it projects a threatening image corresponding to the threatening image data in accordance with this control signal. For example, projection device 500C projects a threatening image containing the words "Security is in operation. Leave immediately" onto a transparent screen installed in window W3. Since the threatening image is projected onto window W3, which is visible from the intruder's position, the intruder can be made aware that the surveillance system 10 is operational. In addition to projecting the threatening image, a threatening sound may also be output. Then, the process proceeds to step S28 shown in Figure 8.

[0073] Furthermore, if an intruder enters the interior of building 21, the projection of images by the projection device 500 will be stopped. Also, if an intruder is detected by the indoor intrusion monitoring sensor 100, an alarm will be issued from, for example, the monitoring device 300 under the control of the controller 200.

[0074] According to the embodiment described above, if no intruder is detected in the outdoor monitoring area, the first image for creating the illusion of occupancy can be projected to make it appear as if a resident is inside the building 21. This effectively enables measures such as reconnaissance by potential burglars. On the other hand, if an intruder is detected in the outdoor monitoring area, the second image for creating the illusion of occupancy or a deterrent image can be projected to deter the intruder from entering the building 21. Furthermore, if an intruder is detected, the second image for creating the illusion of occupancy or a deterrent image is projected in an area visible to the intruder, effectively deterring the intruder from entering the building 21. In addition, if the distance from the building 21 to the intruder is outside the proximity range 22, the second image for creating the illusion of occupancy is projected, and if it is within the proximity range 22, a deterrent image is projected, effectively deterring intruders approaching the building 21 from entering.

[0075] Furthermore, if no intruder is detected, the first occupancy image is projected onto the area corresponding to the security mode, thereby effectively deterring intruders from entering the building 21. For example, when the alert mode is set, the first occupancy image is projected onto the area visible from the road, thereby effectively deterring intruders from entering the building 21 from the road. When the deactivation mode is set, the first occupancy image is projected onto the area where no residents are present, thereby effectively deterring intruders from entering areas where no residents are present. When the partial alert mode is set, the first occupancy image is projected onto the area designated as the target of alert in the partial alert mode, thereby effectively deterring intruders from entering the area designated as the target of alert.

[0076] 3. Variant The present invention is not limited to the embodiments described above, and may be modified as follows. The following modifications may be used individually or in combination.

[0077] In the embodiment described above, if no intruder is detected in the outdoor monitoring area of ​​building 21, the first occupancy image may be projected onto an area of ​​building 21 that is visible from the road, regardless of the security mode. In another example, if no intruder is detected in the outdoor monitoring area, the first occupancy image may be projected onto a predetermined area of ​​building 21, regardless of the security mode. Even with this configuration, intruders can be effectively deterred from entering building 21.

[0078] In the embodiment described above, the projection area for the second home presence image or intimidation image may be determined based on the location of the person detected in the outdoor monitoring area. For example, when monitoring a wide area with a single intrusion monitoring sensor 100 rather than multiple sensors such as image sensors, a window visible from the location of the detected person is determined as the projection area. Specifically, the monitoring range may be divided into multiple sub-areas in advance, and instead of the sensor ID in the area table 221, the sub-areas and the windows visible from each sub-area may be associated and stored. In this case, the window associated with the sub-area where the detected person is located is determined as the projection area. Note that multiple windows may be associated with each sub-area, and the projection area may be determined based on the positional relationship between the window associated with the person's location within the sub-area. Preferably, the window closest to the person's location is determined as the projection area. Alternatively, the area table 221 may not be used, and the window closest to the detected person's location may be determined as the projection area. Note that in addition to the closest window, the second closest window may also be determined as the projection area. The distance between a person and each window is calculated from the detection results of the intrusion monitoring sensor 100. For example, the distance between a detected person and each window can be calculated from the position of the person in the captured image and the position of each window, or from the distance of the person detected by the laser sensor from the sensor and the distance between the pre-stored sensor installation position and the position of each window.

[0079] In the embodiment described above, the area of ​​building 21 onto which the projection device 500 projects an image is not limited to windows. The area of ​​building 21 onto which the projection device 500 projects an image may be a door or an exterior wall of building 21. When projecting an image onto the exterior wall of building 21, the projection device 500 is installed outside building 21. For example, the projection device 500 may project an image showing windows and human figures onto the exterior wall of building 21. Even with this configuration, it is possible to effectively deter intruders from entering building 21.

[0080] In the embodiment described above, the projection device 500 may be a 3D hologram device. The 3D hologram device projects a three-dimensional hologram image. The 3D hologram device may be installed embedded in the outer wall of the building 21. Even with this configuration, it is possible to effectively deter intruders from entering the building 21.

[0081] In the embodiments described above, the security effect is not limited to the projection of an image by the projection device 500. For example, the security effect may include turning on lights by a lighting device, outputting sound from indoor speakers, displaying images on a television, and playing back sound. The security effect may be a combination of at least one of the following: turning on lights by a lighting device, outputting sound from indoor speakers, and displaying images and playing back sound on a television, and projection of an image by the projection device 500, or it may be turning on lights by a lighting device, outputting sound from indoor speakers, or displaying images and playing back sound on a television, or a combination of at least two of these. The lighting device, indoor speakers, and television are examples of the effect units according to the present invention. When the security effect includes turning on lights by a lighting device, the effect control unit 215 controls the lighting device corresponding to the area determined by the determination unit 213 to turn on. When the security effect includes outputting sound from indoor speakers, the effect control unit 215 controls the indoor speaker corresponding to the area determined by the determination unit 213 to output sound. When the security measures include displaying images and playing audio on a television, the effects control unit 215 controls the television corresponding to the area determined by the determination unit 213 to display images and play audio. Even with this configuration, intruders can be effectively deterred from entering the building 21. Furthermore, even when security measures are used with lighting devices, if an intruder is detected in the outdoor monitoring area, the system switches to a security measure that projects images. By projecting images of people or other figures, intruders can sense the presence of people more effectively than with lighting devices, thus effectively deterring intrusion.

[0082] In the embodiment described above, if an intruder is detected in the outdoor monitoring area, the second image projected to indicate that the building is occupied may be changed according to the attributes of the intruder. If the intrusion monitoring sensor 100 is an image sensor, it is determined by facial recognition whether the detected intruder is a resident of the building 21, and if the intruder is not a resident, the second image projected to indicate that the building is occupied is projected. On the other hand, if the intruder is a resident, the security effect is stopped or the projection of the first image projected to indicate that the building is occupied is continued.

[0083] In the embodiments described above, the configuration, functions, and operation of the monitoring system 10 are not limited to the examples described above. Each device constituting the monitoring system 10 may have a configuration different from the configuration described in the embodiments described above, or it may be configured without some of the configurations. Each device constituting the monitoring system 10 may have a function different from the functions described in the embodiments described above, or it may be configured without some of the functions. Furthermore, the functions of one device may be distributed among multiple devices, or the functions of multiple devices may be combined into one device. The processing steps of the monitoring system 10 may be rearranged as long as they do not contradict each other. Furthermore, some of the processing steps of the monitoring system 10 may be omitted.

[0084] Another embodiment of the present invention may provide a method having steps of processing performed in at least one of the following: a monitoring system 10, an intrusion monitoring sensor 100, a controller 200, a monitoring device 300, a server device 400, a projection device 500, and a speaker 600. Yet another embodiment of the present invention may provide a program to be executed in the intrusion monitoring sensor 100, the controller 200, the monitoring device 300, the server device 400, the projection device 500, or the speaker 600. This program may be provided stored on a computer-readable recording medium or provided by download via the Internet or the like.

[0085] In the embodiment described above, the determination unit 213 may determine the area to be enhanced with security measures depending on whether a person is present inside the building 21. In this modified example, the controller 200 further includes a determination unit that determines whether a person is present inside the building 21 based on detection information output from the indoor intrusion monitoring sensor 100. For example, the determination unit determines that the person is present if the indoor intrusion monitoring sensor 100 detects a person, and determines that the person is absent if the indoor intrusion monitoring sensor 100 does not detect a person. If the intrusion monitoring sensor 100 does not detect an intruder in the outdoor monitoring area, and the determination unit determines that the person is absent, the determination unit 213 may determine the area visible from the road as the area to be enhanced with security measures, similar to when the above-described alert mode is set. On the other hand, if the intrusion monitoring sensor 100 does not detect an intruder in the outdoor monitoring area, and the determination unit determines that the occupancy status is that the occupant is present, the determination unit 213 may determine that an area where no residents are present is the area where the security measures will be implemented, similar to when the deactivation mode described above is set.

[0086] In the embodiment described above, if the intrusion monitoring sensor 100 does not detect an intruder in the outdoor monitoring area, the determination unit 213 may determine an area of ​​the building 21 visible from the road to be used for security measures. For example, if the intrusion monitoring sensor 100 does not detect an intruder in the outdoor monitoring area and the setting unit 212 has set the partial security mode, the determination unit 213 may determine an area of ​​the building 21 visible from the road that is set as a monitoring target in the partial security mode to be used for security measures. Alternatively, if the intrusion monitoring sensor 100 does not detect an intruder in the outdoor monitoring area and the setting unit 212 has set the deactivation mode, the determination unit 213 may determine an area of ​​the building 21 visible from the road that does not have residents to be used for security measures.
