[0008] [Figure 1] FIG. 1 is a block diagram of a monitoring device according to this embodiment. [Figure 2] FIG. 2 is a flowchart showing the process flow of the monitoring control of the controller. [Figure 3] FIG. 3 is a plan view of the parked vehicle and the surrounding area of ​​the vehicle. DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of a monitoring device according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of the configuration of a monitoring device according to this embodiment. The monitoring device 1 is mounted on a vehicle (mobile object) and monitors suspicious individuals around the vehicle. The monitoring device 1 monitors the surroundings of the vehicle based on information received from a sensor that detects the surroundings of the vehicle. As shown in FIG. 1, the monitoring device 1 includes a camera 10, a radio wave detection device 20, a communication device 30, a display 40, and a controller 50. The camera 10 captures images of the surroundings of the vehicle and transmits the captured images to the controller 50. The camera 10 is mounted on the vehicle and may be used, for example, for around-view systems or autonomous driving control. The radio wave detection device 20 emits radio waves around the vehicle and receives radio waves reflected by obstacles to detect the position, direction, and distance of obstacles around the vehicle from the vehicle. The radio wave detection device 20 is a ranging radar or the like and transmits a detection signal to the controller 50. The camera 10 and / or the radio wave detection device 20 correspond to sensors that detect the surroundings of the vehicle.

[0010] The communication device 30 is a device that communicates with the outside of the vehicle, and connects to an external system via the Internet to obtain information necessary for monitoring by the monitoring device 1. The communication device 30 can also connect to a communication terminal such as a user terminal, and can transmit, for example, the monitoring results of the monitoring device 1 and suspicious person information to the communication terminal. The display 40 is mounted on the vehicle and displays map information, etc. As will be described later, the controller 50 displays the contents of monitoring settings recommended to the user on the display 40. The display 40 may be a touch panel display that can detect touch operations by the user. Note that the controller 50 is not limited to the on-vehicle display 40, and may, for example, be connected to a user terminal via the communication device 30 and display the contents of monitoring settings recommended to the user on the display screen of the user terminal.

[0011] The controller 50 has functions such as acquiring attributes of the parking location, calculating a monitoring level, determining monitoring settings, and outputting signals related to the monitoring settings, and has an attribute acquisition unit 51, a monitoring setting unit 52, and a signal output unit 53 as functional blocks for executing each function. The controller 50 has a memory for storing programs and a processor for executing the programs, and the processor executes the programs stored in the memory or the like to perform each function of the functional blocks. Note that the controller 50 may have other functions in addition to the functions of each functional block.

[0012] The attribute acquisition unit 51 acquires attribute information indicating the attributes of the parking space where the vehicle is parked. The attributes of the parking space indicate the crime prevention characteristics and / or the possibility of a crime occurring (necessity of crime prevention) determined by the parking space and the surrounding environment of the parking space, and are determined by crime occurrence history, crime prevention equipment installed around the parking space, the surrounding structure of the parking space, the parking equipment, the time of parking, the date and time of parking, etc. The attribute information is information indicating the attributes and includes at least one of crime occurrence information, crime prevention equipment information, and obstacle information. The attribute acquisition unit 51 acquires the attribute information at a predetermined interval via the communication device 30. Furthermore, the attribute acquisition unit 51 may acquire the crime prevention equipment information and obstacle information from the camera 10 and / or the radio wave detection device 20. Yo The attribute information is not limited to crime occurrence information, security equipment information, and obstacle information, but may also be other information such as parking time information.

[0013] The crime occurrence information indicates the crime occurrence status in the vicinity of the parking space. The attribute acquisition unit 51 connects to a crime prevention management system that manages information related to crime prevention via the communication device 30 and receives data related to the crime occurrence status from the system. Crime prevention management systems are systems operated by administrative agencies such as police, fire departments, cities, prefectures, and the country, as well as private agencies that operate Internet-related businesses. The crime prevention management system has a crime prevention map (crime occurrence map) that stores the time, location, and details of crimes, etc., in association with map information. The attribute acquisition unit 51 then acquires crime occurrence information by receiving the crime prevention map data.

[0014] The crime occurrence information may be external information posted by an unspecified number of users on a social networking service (SNS). For example, if a user learns of a crime from a media outlet reporting the crime or sees a crime scene, the user may post information about the crime to alert other users. The attribute acquisition unit 51 determines whether external information about a crime has been posted around the current location of the parked vehicle, and if external information has been posted, searches for text information, image information, and location information (GPS information) associated with the external information. The attribute acquisition unit 51 then identifies the crime occurrence information by extracting information about the crime from the search results.

[0015] The security equipment information is information about the security equipment installed in the parking space. The attribute acquisition unit 51 is connected to a surveillance camera management system that manages the positions of surveillance cameras via the communication device 30, and acquires from the system the information about the security equipment installed around the parking space. Monitoring Camera position and / or Monitoring Receive data about the camera's coverage area. Monitoring The camera management system provides users with, for example, an application (hereinafter referred to as an app) that displays the positions of surveillance cameras on a map. Monitoring Connect to the camera management system and use the app to view the parking lot within a 100m radius. Monitoring The attribute acquiring unit 51 may acquire the security equipment information by identifying the position of the surveillance camera from the image captured by the camera 10.

[0016] The obstacle information is information about surrounding obstacles located around the parking space. The attribute acquisition unit 51 acquires the obstacle information by detecting obstacles around the vehicle using the camera 10 and / or the radio wave detection device 20. For example, when a vehicle is parked in an indoor garage at home or a multi-story parking space, the possibility of a suspicious person entering and causing harm to the vehicle is low. Therefore, the attribute acquisition unit 51 acquires the obstacle information as attribute information of the parking space. The obstacle information may include position information of the obstacle. For example, when a wall is installed facing the left side of the vehicle, the possibility of a suspicious person entering the parking space from the left side of the vehicle is low. Therefore, the attribute acquisition unit 51 may acquire position information of the obstacle or information about the structure of the obstacle as attribute information of the parking space.

[0017] The monitoring setting unit 52 calculates the monitoring level of the surroundings of the vehicle based on the attribute information, and determines the monitoring setting according to the monitoring level. The monitoring level is an index showing the necessity of monitoring, and the higher the monitoring level, the higher the necessity of monitoring and the higher the risk of crime occurring. Crimes include car break-ins, theft of a vehicle, damage to property (vandalism) to a vehicle, etc. The monitoring setting determines the monitoring level of the cameras 10 and / or the camera 11 to monitor the surroundings of the vehicle according to the monitoring level. or 10 shows the operating conditions of the radio wave detection device 20. The monitoring setting unit 52 calculates the monitoring level based on at least one of crime occurrence information, security equipment information, and obstacle information, or other information.

[0018] A method for calculating the monitoring level will be described below. Note that the monitoring level does not need to be a continuously changing value for parameters included in the attribute information, such as the number of crimes, described below, but may be a stepped value. For example, the monitoring setting unit 52 calculates the monitoring level so that the monitoring level increases as the number of crimes occurring around the parking space increases. For example, the monitoring setting unit 52 calculates the monitoring level so that the monitoring level increases as the crime location is closer to the parking space. Furthermore, the monitoring setting unit 52 calculates the monitoring level so that the monitoring level increases as the date and time of a crime occurring around the parking space is closer to the current time. The monitoring setting unit 52 may calculate the monitoring level by combining the number of crimes, the location of the crime, the date and time of the crime, etc. Furthermore, the monitoring setting unit 52 may calculate the monitoring level according to the type and frequency of crime.

[0019] For example, the monitoring setting unit 52 calculates the monitoring level so that the more security equipment, such as surveillance cameras, installed around the parking space, the higher the monitoring level. For example, the monitoring setting unit 52 calculates the monitoring level so that the closer the security equipment is located to the parking space, the higher the monitoring level. Also, for example, the monitoring setting unit 52 calculates the monitoring level so that the lower the security level provided by the security equipment, the higher the monitoring level. The security level is an index determined by the installation status of the security equipment, such as the number of security equipment, the type of security equipment, and the performance of the security equipment. The monitoring setting unit 52 may calculate the monitoring level by combining the number of security equipment, the location of the security equipment, the security level provided by the security equipment, etc.

[0020] For example, the monitoring setting unit 52 calculates a monitoring level such that when the distance between the vehicle and the position of a surrounding obstacle (such as a wall or tree) indicated by the obstacle information is less than a predetermined distance, the monitoring level is lower than when the distance is greater than the predetermined distance. The predetermined distance is a distance threshold for determining whether there is enough space between the vehicle and the surrounding obstacle for a suspicious individual to enter, and is set to, for example, 30 to 50 cm. The monitoring setting unit 52 may determine whether the distance between the vehicle and the position of the surrounding obstacle is less than a predetermined distance in each of the directions in front, behind, left, and right of the vehicle, and may lower the monitoring level as the number of locations where the distance is less than the predetermined distance increases. This allows a correlation between the monitoring level and the possibility of a suspicious individual entering the vehicle. The monitoring setting unit 52 may calculate the monitoring level by combining a method for calculating the monitoring level based on crime occurrence information, a method for calculating the monitoring level based on security equipment information, and a method for calculating the monitoring level based on obstacle information.

[0021] The monitoring setting unit 52 determines a monitoring setting according to the monitoring level. The monitoring setting determines the type of sensors (cameras 10, radio wave detection devices 20, etc.) to be activated for monitoring, the number of sensors to be activated, or the sensor operation method. The monitoring setting unit 52 determines the monitoring setting by specifying at least one element of the sensor sensitivity, the number of sensors to be activated among the multiple sensors, and the type of sensors to be activated among the multiple sensors. The monitoring setting unit 52 also determines the monitoring setting so that the power consumption of the sensors (cameras 10, radio wave detection devices 20, etc.) decreases as the monitoring level decreases. For example, the monitoring setting unit 52 determines the monitoring setting by specifying the number of cameras to be activated during monitoring, the positions of the cameras to be activated, the imaging cycle of the cameras, the imaging range of the cameras, etc., among the four cameras (cameras that capture images in the front, rear, left, and right directions of the vehicle) installed on the vehicle. For example, the higher the monitoring level, the more cameras to be activated and the shorter the imaging cycle of the cameras. For example, the monitoring setting unit 52 determines monitoring settings for multiple radio wave detection devices 20 that detect four directions of the vehicle (front, rear, left and right directions of the vehicle) by specifying an operation method similar to that of the camera 10.

[0022] Furthermore, since the power consumption of the camera 10 is generally smaller than that of the radio wave detection device 20, when the monitoring level is high, the monitoring setting unit 52 operates both the camera 10 and the radio wave detection device 20 during monitoring. On the other hand, when the monitoring level is low, the monitoring setting unit 52 operates the camera 10 during monitoring but does not operate the radio wave detection device 20. When the monitoring level is even lower, the monitoring setting unit 52 operates the radio wave detection device 20 during monitoring but does not operate the camera 10.

[0023] The monitoring setting unit 52 then determines the monitoring settings so that the lower the monitoring level, the weaker the monitoring function using the camera 10 and / or the radio wave detection device 20. Once the monitoring setting unit 52 determines the monitoring setting, it outputs a recommendation command to the signal output unit 53 to recommend the content of the monitoring setting determined on the controller side to the user.

[0024] When the signal output unit 53 receives a recommendation command from the monitoring setting unit 52, it generates a recommendation signal for recommending the content of the monitoring setting determined by the monitoring setting unit 52 to the user and outputs the recommendation signal to the display 40. The recommendation signal includes the content of the monitoring setting, and the content of the monitoring setting is displayed on the display 40. The content of the monitoring setting displayed on the display 40 includes, for example, the on / off status of sensors such as the camera 10 and / or the radio wave detection device 20. The recommendation signal may also include information about the monitoring level. By viewing the display screen of the display 40, the user can understand the content of the monitoring setting recommended by the monitoring device 1 (system side) and the monitoring level of the parking location. That is, in this embodiment, before controlling and monitoring the sensors such as the camera 10 and / or the radio wave detection device 20 using the monitoring setting determined by the controller side, the signal output unit 53 recommends to the user whether to turn on or off the sensors for monitoring. Note that in this embodiment, the signal output unit 53 may output the recommendation signal to a speaker to recommend the content of the monitoring setting to the user by voice.

[0025] When the user starts monitoring the surroundings of the vehicle with the recommended monitoring settings, the user performs an operation (for example, a touch operation on the display 40) to accept the recommended monitoring settings. Note that the user may also operate the display 40 to change the content of the monitoring settings.

[0026] When the signal output unit 53 receives an operation command from the display 40 to approve the recommended monitoring settings or to change the monitoring settings, the monitoring setting unit 52 confirms the monitoring settings, and the signal output unit 53 outputs an instruction signal to control the camera 10 and / or the radio wave detection device 20 with the monitoring settings. Upon receiving the instruction signal, the camera 10 and / or the radio wave detection device 20 operate under the conditions of the monitoring settings indicated by the instruction signal. This starts monitoring. Note that the controller 50 may control the camera 10 and / or the radio wave detection device 20 according to the monitoring settings and start monitoring without recommending the monitoring settings determined by the monitoring setting unit 52 to the user. In this case, the monitoring setting unit 52 does not need to send a recommendation command to the signal output unit 53, and the signal output unit 53 may simply output an instruction signal to control the camera 10 and / or the radio wave detection device 20 with the monitoring settings determined by the monitoring setting unit 52.

[0027] Next, a monitoring method executed by the controller 50 will be described with reference to Fig. 2. Fig. 2 is a flowchart showing the processing flow of monitoring control by the controller 50. When the vehicle is parked in a parking space, the controller 50 executes the following control flow.

[0028] In step S1, the attribute acquisition unit 51 of the controller 50 acquires attribute information. In the control flow from step S2 onwards, the monitoring setting unit 52 of the controller 50 calculates a monitoring level based on the crime occurrence information and security equipment information from the attribute information, as an example of a method for calculating the monitoring level. The monitoring level is calculated on one of four levels, 1 to 4. In step S2, the monitoring setting unit 52 of the controller 50 identifies the number of crimes from the crime occurrence information and determines whether the number of crimes is equal to or less than a threshold number of crimes (a predetermined value). If the number of crimes is equal to or less than the threshold number of crimes, in step S3, the monitoring setting unit 52 identifies the crime prevention level from the security equipment information and determines whether the crime prevention level is equal to or less than a predetermined threshold level (a predetermined level). If the crime prevention level is equal to or less than the predetermined threshold level (a predetermined level), the monitoring setting unit 52 calculates the monitoring level as "monitoring level 1" (step S4). If the security level is higher than the predetermined level threshold (predetermined level), the monitoring setting unit 52 calculates the monitoring level as "monitoring level 2" (step S5).

[0029] If the determination in step S2 indicates that the number of crimes is greater than the crime threshold, then in step S6 the monitoring setting unit 52 determines whether the crime prevention level is equal to or less than a predetermined threshold level. If the crime prevention level is equal to or less than the predetermined threshold level (predetermined level), the monitoring setting unit 52 calculates the monitoring level as "monitoring level 3" (step S7). If the crime prevention level is higher than the predetermined threshold level (predetermined level), the monitoring setting unit 52 calculates the monitoring level as "monitoring level 4" (step S8).

[0030] In this way, when the number of crimes is equal to or less than the crime threshold, the monitoring setting unit 52 sets a lower monitoring level than when the number of crimes is greater than the crime threshold. Also, when the crime prevention level is equal to or less than the level threshold, the monitoring setting unit 52 sets a lower monitoring level than when the crime prevention level is greater than the level threshold. This allows the monitoring level to be correlated with the crime number and crime prevention level.

[0031] After "monitoring level 1" is calculated by the control flow of step S4, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 1" in step S9, and the signal output unit 53 outputs a recommendation signal to recommend the content of the monitoring setting to the user. After "monitoring level 2" is calculated by the control flow of step S5, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 2" in step S10, and the signal output unit 53 outputs a recommendation signal to recommend the content of the monitoring setting to the user. After "monitoring level 3" is calculated by the control flow of step S7, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 3" in step S11, and the signal output unit 53 outputs a recommendation signal to recommend the content of the monitoring setting to the user. After "monitoring level 4" is calculated by the control flow of step S8, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 4" in step S12, and the signal output unit 53 outputs a recommendation signal to recommend the content of the monitoring setting to the user.

[0032] For example, the monitoring setting unit 52 determines monitoring settings corresponding to four levels based on the type of sensor that operates during monitoring and the detection cycle of the sensor. Specifically, in the case of "monitoring level 1," the monitoring setting is set so that the camera 10 and the radio wave detection device 20 are not operated. The user is advised not to operate the camera 10 and the radio wave detection device 20.

[0033] In the case of "Monitoring Level 2," the setting is made so that only one of the camera 10 and the radio wave detection device 20 is operated. The user is recommended to operate only one of the camera 10 and the radio wave detection device 20. Note that which of the camera 10 and the radio wave detection device 20 is to be operated may be determined, for example, according to the remaining capacity of the in-vehicle battery (battery SOC). Alternatively, it may be specified by the user.

[0034] Furthermore, in the case of "monitoring level 3," both the camera 10 and the radio wave detection device 20 are operated, and the detection cycles of the camera 10 and the radio wave detection device 20 are lengthened. The detection cycle corresponds to the imaging timing cycle of the camera 10 and the radio wave transmission cycle of the radio wave detection device 20. The user is then recommended to operate both the camera 10 and the radio wave detection device 20 at a long detection cycle. At this time, the user may be notified, for example, of the power consumption per unit time of the camera 10 and the radio wave detection device 20 and the battery capacity used for monitoring.

[0035] Furthermore, in the case of "monitoring level 4," both the camera 10 and the radio wave detection device 20 are operated, and the detection cycles of the camera 10 and the radio wave detection device 20 are shortened. The user is encouraged to operate both the camera 10 and the radio wave detection device 20 at a short detection cycle. As in the case of "monitoring level 3," the user may be notified of power consumption, etc.

[0036] In step S13, the monitoring setting unit 52 determines a monitoring range based on the structure surrounding the parking space. The method for determining the monitoring range will be described with reference to FIG. 3. FIG. 3 is a plan view of the parked vehicle and its surroundings. The monitoring setting unit 52 detects barriers in each direction, in front of, behind, to the left, and to the right of the vehicle, based on the obstacle information, and identifies the position of an open surface from the detection results. The monitoring setting unit 52 detects barriers around the vehicle from the image captured by the camera 10 and / or the detection results of the radio wave detection device 20. The monitoring setting unit 52 also measures the distance between the position of the barrier and the vehicle and determines whether the measured distance is equal to or less than a predetermined distance. If the measured distance is equal to or less than the predetermined distance, the monitoring setting unit 52 identifies the direction in which the barrier is located as a closed surface. If the measured distance is longer than the predetermined distance or if the monitoring setting unit 52 cannot detect a barrier, the monitoring setting unit 52 identifies the direction in which the barrier is located as an open surface. The monitoring setting unit 52 identifies closed surfaces and open surfaces in the four directions around the vehicle. The direction in which the closing surface faces the vehicle corresponds to the direction in which the barrier (corresponding to the "surrounding obstacle" in the present invention) faces the vehicle.

[0037] As shown in FIG. 3(a), when the open surface is the front of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the front. As shown in FIG. 3(b), when the open surface is the rear of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the rear. As shown in FIG. 3(c), when the open surface is the right side of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the right side. As shown in FIG. 3(d), when the open surface is the left side of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the left side. As shown in FIG. 3(e), when the open surface is the front and right sides of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the front and right sides. As shown in FIG. 3(f), when the open surface is the front and left sides of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the front and left sides. As shown in FIG. 3(g), when the open surface is the rear and right sides of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the rear and right sides. 3(h), when the open surfaces are the rear and left side of the vehicle, the monitoring setting unit 52 determines the monitoring range to be the rear and left side. When the open surfaces are all four sides, the monitoring setting unit 52 determines the monitoring range to be the entire perimeter. Then, the controller 50 includes the monitoring range determined by the controller in the monitoring setting and recommends the monitoring setting to the user.

[0038] In step S14, the signal output unit 53 receives an operation command (user instruction) to approve the recommended monitoring settings or an operation command (user instruction) to change the monitoring settings. In step S15, the monitoring setting unit 52 confirms the monitoring settings. In step S16, the signal output unit 53 outputs an instruction signal for controlling the camera 10 and / or the radio wave detection device 20 with the monitoring settings, thereby instructing the camera 10 and / or the radio wave detection device 20 to operate. Step S1 7 Monitoring will begin.

[0039] As described above, in this embodiment, the controller 50 acquires attribute information indicating the attributes of the parking space where the vehicle is parked, calculates a monitoring level for the area around the vehicle based on the attribute information, determines a monitoring setting according to the monitoring level, and outputs a recommendation signal to recommend the monitoring setting to the user and / or an instruction signal to control the camera 10 and / or the radio wave detection device 20 with the monitoring setting. This allows the monitoring function to be maintained while reducing power consumption. Furthermore, the controller 50 can reduce power consumption by recommending a monitoring setting to the user based on the attributes of the parking space.

[0040] In this embodiment, the attribute information includes at least one of the following information: crime occurrence information indicating the crime occurrence status around the parking space; security equipment information regarding security equipment installed at the parking space; and obstacle information regarding surrounding obstacles located around the parking space. This allows the attributes of the parking space to be classified based on one of the crime occurrence information, security equipment information, and obstacle information.

[0041] In this embodiment, when the distance between the vehicle and the position of a surrounding obstacle indicated by the obstacle information is equal to or shorter than a predetermined distance, the monitoring setting unit 52 determines the monitoring setting so that the camera 10 and / or the radio wave detection device 20 does not detect the direction of the surrounding obstacle relative to the vehicle, thereby reducing power consumption.

[0042] In this embodiment, the security level is determined according to the location of the security equipment and / or the number of security equipment, thereby creating a correlation between the security level and the location of the security equipment and / or the number of security equipment.

[0043] As a modification of this embodiment, the monitoring setting unit 52 may be configured to or The monitoring settings may be changed according to the monitoring level by changing the sensitivity of the radio wave detection device 20. or The sensitivity of the radio wave detection device 20 is determined based on the number of detections, the detection time, the size of the detection range, the detection conditions for the suspicious person, the camera 10 and / or orThis can be adjusted by the operation timing of the radio wave detection device 20. The monitoring setting unit 52 can change the monitoring setting so that the higher the monitoring level, the higher the sensitivity.

[0044] For example, when the camera 10 captures images of the surroundings of the vehicle at a predetermined interval and the same person is captured multiple times, the monitoring setting unit 52 determines that the person is a suspicious person. In this case, the monitoring setting unit 52 can lower the sensitivity by increasing the threshold value for the number of times a suspicious person has been captured, which is used to determine that the person is a suspicious person.

[0045] For example, when the camera 10 captures images of the surroundings of the vehicle at a predetermined cycle and the same person is continuously captured within a predetermined determination time, the monitoring setting unit 52 determines that the person is a suspicious person. In this case, the monitoring setting unit 52 can lower the sensitivity by lengthening the determination time for determining that the person is a suspicious person.

[0046] For example, if the imaging range of the camera 10 can be adjusted, the monitoring setting unit 52 can reduce the sensitivity by narrowing the imaging range of the camera.

[0047] For example, the monitoring setting unit 52 may detect a suspicious person as a condition for detecting a suspicious person when a characteristic movement of a suspicious person or a face that is not that of a registered user, such as the owner of a vehicle, is identified from an image captured by the camera 10. In this case, the monitoring setting unit 52 may adjust the sensitivity by, for example, changing a determination threshold for the number of times a characteristic movement is detected or a determination threshold for the number of times a face that is not that of a registered user is detected.

[0048] For example, the monitoring setting unit 52 determines that a suspicious person is present when both conditions are met: a suspicious person is detected in an image captured by the camera 10, and a suspicious person is detected from the detection results of the radio wave detection device 20. Alternatively, the monitoring setting unit 52 operates only the radio wave detection device 20, and when a suspicious person is detected from the detection results of the radio wave detection device 20, operates the camera 10. In this case, the monitoring setting unit 52 may adjust the sensitivity by adjusting the length of time from when a suspicious person is detected from the detection results of the radio wave detection device 20 to when the camera 10 is started up. In other words, the monitoring setting unit 52 can lower the sensitivity by delaying the operation timing of the camera 10.

[0049] As in the modified example of this embodiment, the lower the monitoring level, the more the monitoring setting unit 52 sets the camera 10 and / or or Power consumption can be reduced by lowering the sensitivity of the radio wave detection device 20. Note that, in the above specific example, a method for setting the sensitivity of the camera 10 has been mainly described, but the sensitivity of the radio wave detection device 20 can also be adjusted in a similar manner by replacing the captured image with the radio waves of the radio wave detection device 20.

[0050] It should be noted that the above-described embodiments have been described to facilitate understanding of the present invention, and are not intended to limit the present invention.
