Embodiments for Carrying Out the Invention

[0009] An embodiment of the 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 the monitoring device according to this embodiment. The monitoring device 1 is mounted on a vehicle (mobile body) and monitors suspicious persons around the vehicle. The monitoring device 1 monitors the surroundings of the vehicle based on information received from sensors that detect 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 an image of the surroundings of the vehicle and transmits the captured image to the controller 50. The camera 10 is provided on the vehicle and may be used, for example, for an around view or automatic driving control. The radio wave detection device 20 emits radio waves around the vehicle, receives the radio waves reflected by an obstacle, and detects the position, direction, and distance from the vehicle to the obstacle of the obstacle around the vehicle. The radio wave detection device 20 is a ranging radar or the like and transmits a detection signal to the controller 50. Note that the camera 10 and / or the radio wave detection device 20 corresponds to a sensor that detects the surroundings of the vehicle.

[0010] The communication device 30 is a device that communicates with the outside of the vehicle, connects to an external system via the Internet, and acquires information necessary for monitoring by the monitoring device 1. Further, the communication device 30 can connect a communication terminal such as a user terminal, and can transmit, for example, the monitoring result or suspicious person information of the monitoring device 1 to the communication terminal. The display 40 is mounted on the vehicle and displays map information and the like. As will be described later, the controller 50 causes the display 40 to display the content of the monitoring setting recommended to the user. The display 40 may be a touch panel display that can detect a touch operation by the user. Note that the controller 50 is not limited to the in-vehicle display 40, and may be connected to a user terminal via, for example, the communication device 30 and display the content of the monitoring setting recommended to the user on the display screen of the user terminal.

[0011] The controller 50 has functions such as acquiring the attributes of the parking location, calculating the monitoring level, determining the monitoring settings, and outputting signals related to the monitoring settings. As functional blocks for executing each function, it has an attribute acquisition unit 51, a monitoring setting unit 52, and a signal output unit 53. The controller 50 has a memory for storing programs and a processor for executing the programs. By the processor executing the programs stored in the memory and the like, each function of the functional blocks is exerted. Note that the controller 50 may have other functions not limited to the functions in each functional block.

[0012] The attribute acquisition unit 51 acquires attribute information indicating the attributes of the parking location where the vehicle is parked. The attributes of the parking location indicate the security characteristics and / or the likelihood of crime occurrence (security necessity) determined by the parking location and the surrounding environment of the parking location, and are determined by the crime occurrence history, security facilities installed around the parking location, the surrounding structure of the parking location, parking facilities, parking time, parking date and time, etc. The attribute information is information indicating the attributes and includes at least any one of crime occurrence information, security facility information, and obstacle information. The attribute acquisition unit 51 acquires the attribute information at a predetermined period via the communication device 30. Also, the attribute acquisition unit 51 may acquire security facility information and obstacle information from the camera 10 and / or the radio wave detection device 20. yo Note that the attribute information is not limited to crime occurrence information, security facility information, and obstacle information, and may be other information such as parking time information.

[0013] The crime occurrence information indicates the crime occurrence situation around the parking location. The attribute acquisition unit 51 connects to a security management system that manages information related to security via the communication device 30 and receives data related to the crime occurrence situation from the system. The security management system is a system operated by administrative agencies such as police, fire departments, cities, prefectures, and countries, or private agencies that operate Internet-related services, etc. The security management system has a security map (crime occurrence map) that stores the crime occurrence time, occurrence location, crime content, etc. in correspondence with map information. Then, the attribute acquisition unit 51 acquires the crime occurrence information by receiving the data of the security map.

[0014] The crime occurrence information may be external information posted by an unspecified number of users, such as on a social networking service (SNS). For example, when 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 the external information has been posted, searches for character 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 security equipment installed in the parking space. The attribute acquisition unit 51 is connected to a security camera management system that manages the positions of security cameras via the communication device 30, and acquires information about security equipment installed around the parking space from the system. monitoring Camera position and / or monitoring Receive data regarding 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 view the parking lot information within a 100m radius on the app. monitoring The attribute acquiring unit 51 may acquire the security equipment information by identifying the position of the surveillance camera from the captured image of the camera 10.

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

[0017] The monitoring setting unit 52 calculates the monitoring level around the vehicle based on the attribute information and determines the monitoring setting according to the monitoring level. The monitoring level is an index indicating the necessity of monitoring. The higher the monitoring level, the higher the necessity of monitoring and the higher the risk of crime occurrence. Note that crime includes acts such as vandalism to the vehicle, theft of the vehicle, and damage to the vehicle's equipment (damage to equipment). The monitoring setting indicates the operating conditions of the camera 10 and / or the radio wave detection device 20 for performing monitoring around the vehicle according to the monitoring level. The monitoring setting unit 52 calculates the monitoring level based on at least one of the crime occurrence information, the security equipment information, and the obstacle information, or other information. or The obstacle information is information regarding surrounding obstacles located around the parking location. The attribute acquisition unit 51 acquires obstacle information by detecting obstacles around the vehicle using the camera 10 and / or the radio wave detection device 20. For example, when the vehicle is parked in an indoor garage at home or a multi-story parking location, etc., the possibility of a suspicious person intruding and causing harm to the vehicle is low. Therefore, the attribute acquisition unit 51 acquires obstacle information as the attribute information of the parking location. The obstacle information may include the 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 location from the left side of the vehicle is low. Therefore, the attribute acquisition unit 51 may acquire the position information of the obstacle or information regarding the structure of the obstacle as the attribute information of the parking location.

[0018] The method for calculating the monitoring level will be described below. Note that the monitoring level does not necessarily have to be a continuously changing value for the parameters included in the attribute information such as the number of criminal occurrences described below, and it may be a stepwise value. For example, the monitoring setting unit 52 calculates the monitoring level such that the higher the number of criminal occurrences around the parking location, the higher the monitoring level. For example, the monitoring setting unit 52 calculates the monitoring level such that the closer the crime occurrence location is to the parking location, the higher the monitoring level. Also, the monitoring setting unit 52 calculates the monitoring level such that the closer the date and time of the crime that occurred around the parking location is to the current time, the higher the monitoring level. The monitoring setting unit 52 may calculate the monitoring level by combining the number of criminal occurrences, the crime occurrence location, the crime occurrence date and time, etc. Also, the monitoring setting unit 52 may calculate the monitoring level according to the type and occurrence frequency of the crime.

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

[0020] For example, when the distance between the position of the surrounding obstacles (such as walls and trees) indicated by the obstacle information and the vehicle is equal to or less than a predetermined distance, the monitoring setting unit 52 calculates the monitoring level so that the monitoring level is lower than when the distance is longer than the predetermined distance. The predetermined distance is a distance threshold for determining whether there is a space where a suspicious person can intrude between the vehicle and the surrounding obstacles, and is set to, for example, 30 to 50 cm. The monitoring setting unit 52 determines whether the distance between the position of the surrounding obstacles and the vehicle is equal to or less than the predetermined distance in each direction of the front, rear, left, and right of the vehicle. The more locations where the distance is equal to or less than the predetermined distance, the lower the monitoring level may be set. Thereby, a correlation can be established between the monitoring level and the possibility of intrusion by a suspicious person. Note that the monitoring setting unit 52 may calculate the monitoring level by combining the method for calculating the monitoring level based on the crime occurrence information, the method for calculating the monitoring level based on the security facility information, and the method for calculating the monitoring level based on the obstacle information.

[0021] The monitoring setting unit 52 determines the monitoring settings according to the monitoring level. The monitoring settings determine the type of sensors (such as the camera 10 and the radio wave detection device 20) that are the operation targets for monitoring, the number of sensors that are the operation targets, or the operation method of the sensors. The monitoring setting unit 52 determines the monitoring settings by specifying at least one of the sensitivity of the sensors, the number of sensors that operate among the plurality of sensors, and the type of sensors that operate among the plurality of sensors. Also, the monitoring setting unit 52 determines the monitoring settings so that the power consumption of the sensors (such as the camera 10 and the radio wave detection device 20) decreases as the monitoring level decreases. For example, the monitoring setting unit 52 determines the monitoring settings by specifying the number of cameras to be operated during monitoring, the positions of the cameras to be operated, the imaging cycle of the cameras, the imaging range of the cameras, etc. among the four cameras provided on the vehicle (cameras that image each direction of the front, rear, left, and right of the vehicle). For example, the higher the monitoring level, the larger the number of cameras to be operated and the shorter the imaging cycle of the cameras. Also, for example, the monitoring setting unit 52 determines the monitoring settings by specifying the same operation method as that of the camera 10 for the plurality of radio wave detection devices 20 that detect the four directions of the vehicle (each direction of the front, rear, left, and right of the vehicle).

[0022] Also, generally, since the power consumption of the camera 10 is 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 and does not operate the radio wave detection device 20 during monitoring. When the monitoring level is even lower, the monitoring setting unit 52 operates the radio wave detection device 20 and does not operate the camera 10 during monitoring.

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

[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 is the on / off, etc. of sensors such as the camera 10 and / or the radio wave detection device 20. The recommendation signal may include information on the monitoring level. By displaying the display screen of the display 40, the user can grasp the content of the monitoring setting recommended by the monitoring device 1 side (system side) and the monitoring level of the parking location. That is, in the present embodiment, before controlling and monitoring sensors such as the camera 10 and / or the radio wave detection device 20 with the monitoring setting determined on the controller side, the user is recommended whether to turn on or off the sensors for monitoring. In the present embodiment, the signal output unit 53 may output the recommendation signal to the 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 (e.g., a touch operation on the display 40) to approve the recommended monitoring settings. Note that the user may operate the display 40 to change the content of the monitoring settings.

[0026] When the signal output unit 53 receives an operation command to approve the recommended monitoring settings or an operation command to change the monitoring settings from the display 40, the monitoring setting unit 52 finalizes the monitoring settings, and the signal output unit 53 outputs an instruction signal for controlling the camera 10 and / or the radio wave detection device 20 according to the monitoring settings. When the camera 10 and / or the radio wave detection device 20 receives the instruction signal, it operates under the conditions of the monitoring settings indicated by the instruction signal. Thereby, the monitoring starts. 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 the monitoring without recommending the monitoring settings determined by the monitoring setting unit 52 to the user. At this time, the monitoring setting unit 52 does not have to transmit a recommendation command to the signal output unit 53, and the signal output unit 53 only needs to output an instruction signal for controlling the camera 10 and / or the radio wave detection device 20 according to the monitoring settings determined by the monitoring setting unit 52.

[0027] Next, with reference to FIG. 2, a monitoring method executed by the controller 50 will be described. FIG. 2 is a flowchart showing the processing flow of the monitoring control of the controller 50. When the vehicle parks in a parking location, 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 after step S2, as an example of the method for calculating the monitoring level, the monitoring setting unit 52 of the controller 50 calculates the monitoring level based on the crime occurrence information and the security facility information among the attribute information. Also, the monitoring level is calculated in four levels from 1 to 4. In step S2, the monitoring setting unit 52 of the controller 50 identifies the number of crime occurrences from the crime occurrence information and determines whether the number of crime occurrences is less than or equal to the occurrence count threshold (predetermined value). If the number of crime occurrences is less than or equal to the occurrence count threshold, then in step S3, the monitoring setting unit 52 identifies the security level from the security facility information and determines whether the security level is less than or equal to a predetermined level threshold (predetermined level). And if the security level is less than or equal to the predetermined level threshold (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] In the determination of step S2, if the number of crime occurrences is more than the occurrence count threshold, then in step S6, the monitoring setting unit 52 determines whether the security level is less than or equal to the predetermined level threshold. If the security level is less than or equal to the predetermined level threshold (predetermined level), the monitoring setting unit 52 calculates the monitoring level as "Monitoring Level 3" (step S7). 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 4" (step S8).

[0030] In this way, when the number of crime occurrences is less than or equal to the occurrence count threshold, the monitoring setting unit 52 sets the monitoring level lower than when the number of crime occurrences is more than the occurrence count threshold. Also, when the security level is less than or equal to the level threshold, the monitoring setting unit 52 sets the monitoring level lower than when the security level is higher than the level threshold. Thereby, the monitoring level can be made correlated with the number of crime occurrences and the security level.

[0031] After "monitoring level 1" is calculated according to the control flow of step S4, in step S9, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 1", and the signal output unit 53 outputs a recommendation signal for recommending the content of the monitoring setting to the user. After "monitoring level 2" is calculated according to the control flow of step S5, in step S10, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 2", and the signal output unit 53 outputs a recommendation signal for recommending the content of the monitoring setting to the user. After "monitoring level 3" is calculated according to the control flow of step S7, in step S11, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 3", and the signal output unit 53 outputs a recommendation signal for recommending the content of the monitoring setting to the user. After "monitoring level 4" is calculated according to the control flow of step S8, in step S12, the monitoring setting unit 52 determines a monitoring setting corresponding to "monitoring level 4", and the signal output unit 53 outputs a recommendation signal for recommending 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 sensors operating during monitoring and the detection period of the sensors. Specifically, in the case of "monitoring level 1", the monitoring setting is such that the camera 10 and the radio wave detection device 20 do not operate. The user is recommended that the camera 10 and the radio wave detection device 20 do not operate.

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

[0034] Also, in the case of "Monitoring Level 3", both the camera 10 and the radio wave detection device 20 are operated to increase the detection periods of the camera 10 and the radio wave detection device 20. The detection period corresponds to the period of the imaging timing of the camera 10 and the radio wave transmission period of the radio wave detection device 20. Then, the user is recommended that both the camera 10 and the radio wave detection device 20 operate with a long detection period. At this time, for example, the power consumption per unit time of the camera 10 and the radio wave detection device 20 and the battery capacity of the battery used for monitoring may be notified to the user.

[0035] Also, in the case of "Monitoring Level 4", both the camera 10 and the radio wave detection device 20 are operated to shorten the detection periods of the camera 10 and the radio wave detection device 20. The user is recommended that both the camera 10 and the radio wave detection device 20 operate with a short detection period. Similar to the case of "Monitoring Level 3", the power consumption, etc. may be notified to the user.

[0036] In step S13, the monitoring setting unit 52 determines the monitoring range based on the structure around the parking location. 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 the surroundings of the vehicle. The monitoring setting unit 52 detects the barriers in the front, rear, left, and right directions of the vehicle based on the obstacle information, and specifies the position of the open surface from the detection results. The monitoring setting unit 52 detects the barriers around the vehicle from the captured image of the camera 10 and / or the detection result 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 less than or equal to a predetermined distance. When the measured distance is less than or equal to the predetermined distance, the monitoring setting unit 52 specifies the direction with the barrier as the closed surface. When the measured distance is longer than the predetermined distance or when the barrier cannot be detected, the monitoring setting unit 52 specifies it as the open surface. The monitoring setting unit 52 specifies the closed surface and the open surface for the four directions around the vehicle. Note that the direction facing the closed surface with respect to the position of the vehicle corresponds to the direction of the barrier (corresponding to the "surrounding obstacle" of the present invention) with respect to the vehicle.

[0037] As shown in Fig. 3(a), when the open surface is the front surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the front surface. As shown in Fig. 3(b), when the open surface is the rear surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the rear surface. As shown in Fig. 3(c), when the open surface is the right side surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the right side surface. As shown in Fig. 3(d), when the open surface is the left side surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the left side surface. As shown in Fig. 3(e), when the open surface is the front surface and the right side surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the front surface and the right side surface. As shown in Fig. 3(f), when the open surface is the front surface and the left side surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the front surface and the left side surface. As shown in Fig. 3(g), when the open surface is the rear surface and the right side surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the rear surface and the right side surface. As shown in Fig. 3(h), when the open surface is the rear surface and the left side surface of the vehicle, the monitoring setting unit 52 determines the monitoring range as the rear surface and the left side surface. Also, when the open surface is the entire four-direction full surface, the monitoring setting unit 52 determines the monitoring range as the entire circumference. Then, the controller 50 recommends the monitoring setting to the user, including the monitoring range determined on the controller side in the monitoring setting.

[0038] In step S14, the signal output unit 53 receives an operation command (user instruction) indicating approval of the recommended monitoring setting or an operation command (user instruction) indicating a change in the monitoring setting. In step S15, the monitoring setting unit 52 finalizes the monitoring setting. 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 according to the monitoring setting, thereby giving an operation instruction to the camera 10 and / or the radio wave detection device 20. In step S1 7 , the monitoring is started.

[0039] As described above, in the present embodiment, the controller 50 acquires attribute information indicating the attributes of the parking location where the vehicle is parked, calculates the monitoring level around the vehicle based on the attribute information, determines a monitoring setting according to the monitoring level, and outputs a recommendation signal for recommending the content of the monitoring setting to the user, and / or an instruction signal for controlling the camera 10 and / or the radio wave detection device 20 according to the monitoring setting. Thereby, the monitoring function can be maintained and the power consumption can be suppressed. Also, based on the attributes of the parking location, the monitoring setting can be recommended to the user and the power consumption can be suppressed.

[0040] Also, in the present embodiment, the attribute information includes at least any one of crime occurrence information indicating the crime occurrence situation around the parking location, security equipment information regarding the security equipment installed at the parking location, and obstacle information regarding the surrounding obstacles located around the parking location. Thereby, the attributes of the parking location can be classified from any one of the crime occurrence information, the security equipment information, and the obstacle information.

[0041] Also, in the present embodiment, when the distance between the position of the surrounding obstacle located around the vehicle indicated by the obstacle information and the vehicle is equal to or less 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 with respect to the vehicle. Thereby, the power consumption can be suppressed.

[0042] Also, in the present embodiment, the security level is determined according to the position and / or the number of the security equipment. Thereby, a correlation can be established between the security level and the position and / or the number of the security equipment.

[0043] As a modification of the present embodiment, the monitoring setting unit 52 may change the monitoring setting according to the monitoring level by changing the sensitivity of the camera 10 and / or or the radio wave detection device 20. The sensitivity of the camera 10 and / or or the radio wave detection device 20 is the number of detections, the detection time, the size of the detection range, the detection conditions for suspicious persons, the camera 10 and / or orIt can be adjusted according to the operation timing of the radio wave detection device 20 and the like. The monitoring setting unit 52 may change the monitoring setting so that the sensitivity increases as the monitoring level increases.

[0044] For example, when the camera 10 images the surroundings of the vehicle at a predetermined cycle and the same person is imaged multiple times, the monitoring setting unit 52 determines that the person is a suspicious person. At this time, the monitoring setting unit 52 can lower the sensitivity by increasing the threshold value of the number of times the suspicious person is imaged for determining that the person is a suspicious person.

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

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

[0047] For example, as a detection condition for a suspicious person, when the monitoring setting unit 52 identifies a unique movement of the suspicious person or a face that is not a registered user such as the owner of the vehicle from the captured image of the camera 10, it may detect the person as a suspicious person. At this time, the monitoring setting unit 52 may adjust the sensitivity by changing, for example, the determination threshold value of the number of times a unique movement is detected and the determination threshold value of the number of times a face that is not a registered user is detected.

[0048] For example, when the monitoring setting unit 52 satisfies both conditions that a suspicious person can be detected in the captured image of the camera 10 and that a suspicious person can be detected from the detection result of the radio wave detection device 20, it determines that there is a suspicious person. Further, when the monitoring setting unit 52 operates only the radio wave detection device 20 and can detect a suspicious person from the detection result of the radio wave detection device 20, it operates the camera 10. At this time, the monitoring setting unit 52 may adjust the sensitivity by adjusting the length from the time when a suspicious person can be detected from the detection result of the radio wave detection device 20 to the start time of the camera 10. That is, the monitoring setting unit 52 can lower the sensitivity by delaying the operation timing of the camera 10.

[0049] And, as in the modification of the present embodiment, the lower the monitoring level, the lower the sensitivities of the camera 10 and / or the radio wave detection device 20, the power consumption can be suppressed. In the above specific example, the method of setting the sensitivity of the camera 10 has been mainly described. However, the sensitivity of the radio wave detection device 20 can also be adjusted in the same way after replacing the captured image with the radio wave of the radio wave detection device 20.

[0050] Note that the embodiments described above are described to facilitate the understanding of the present invention, and are not described to limit the present invention. Therefore, each element disclosed in the above embodiments is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
