Description

[Technical Field]

[0001] The present disclosure relates to an intercom master unit and an intercom system. [Background technology]

[0002] Conventionally, there has been known a security system that uses an intercom system. In such a security system, when a suspicious person is detected, the intercom master unit transmits the detection result to a management device (for example, an external server).

[0003] In the security system described in Patent Document 1, a management device manages video images captured by intercom slave units installed in each home in the area as suspicious person candidates. If the management device determines that a suspicious person candidate included in the video is a suspicious person, the management device notifies the intercom master units of each home that a suspicious person has been detected. Upon receiving the notification, the intercom master units display video images of the suspicious person candidate that the management device has determined to be a suspicious person.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or redundant explanation of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art.

[0016] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0017] <System configuration> The configuration of an intercom system 1 will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of an intercom system 1 according to a first embodiment. The intercom system 1 has a base unit 2 and a handset 3.

[0018] Base unit 2 is installed inside (inside) house A in a living room, kitchen, etc. Handset 3 is installed outside house A near the entrance.

[0019] The base unit 2 communicates with the slave unit 3 by wire or wirelessly. For example, as shown in Fig. 1, the base unit 2 may be configured to be communicably connected to the slave unit 3 via a signal line L1.

[0020] A visitor (person P) to house A operates handset 3 installed outside the house to call a resident (user U) inside the house. The visitor uses handset 3, and the resident uses base unit 2, and the visitor talks to the resident.

[0021] The master unit 2 is communicably connected to a registration device 10 (for example, an external server) via the Internet 100. Search target person data relating to a search target person (searchee) being searched for by a search requester 50 is registered in the registration device 10.

[0022] For example, when person P, a visitor, presses the call button 35 of the slave unit 3, the camera 34 starts capturing an image of person P. The master unit 2 displays the image of person P captured by the camera 34. The resident checks the image of person P displayed on the master unit 2. The captured image data is also saved in the master unit 2.

[0023] Furthermore, the person P captured by the camera 34 is not limited to a visitor to the house A. The person P may also be a suspicious person attempting to burgle the house A, a wandering elderly person, a missing person, a wanted person, or any other person who is the subject of a search or investigation.

[0024] The master unit 2 determines whether or not the person P is a person to be searched for, by referring to the data captured by the camera 34 and the search target person data received from the registration device 10. If the master unit 2 determines that the person P is a person to be searched for, the master unit 2 notifies the search requester 50 that the person P is a person to be searched for (the person to be searched for has been found).

[0025] <Block configuration> 2 and 3, the block configurations of the master device 2, slave device 3, and registration device 10 will be described. Fig. 2 is a diagram showing an example of the block configuration of the master device and slave device according to the first embodiment. Fig. 3 is a diagram showing an example of the block configuration of the registration device 10 according to the first embodiment.

[0026] Block configuration of base unit 2 The block configuration of the base unit 2 will be described with reference to Fig. 2. As shown in Fig. 2, the base unit 2 has a control unit 21, a storage unit 22, a handset communication I / F unit 23, an audio signal control unit 24, a microphone 24a, a speaker 24b, an audio signal bus 25, a display unit 26, a short-range wireless control unit 27, a wireless LAN communication I / F unit 27a, a wireless LAN communication unit 27b, and a wired LAN communication I / F unit 28.

[0027] The control unit 21 controls the overall operation of the base unit 2. The control unit 21 may be configured, for example, by a CPU (Central Processing Unit).

[0028] The control unit 21 includes a person detection unit 21a, a face detection unit 21b, and a person determination unit 21c.

[0029] The person detection unit 21a detects a person captured by the camera 34 of the slave unit 3. A detected image (video frame) including the detected person is stored in the storage unit 22. For example, in response to a person (such as a visitor to the house) pressing the call button 35, the camera 34 starts capturing an image of the person. The detected image acquired by the camera 34 is stored, for example, in the ROM 22a constituting the storage unit 22.

[0030] The person detection unit 21a may also be configured to use a human presence sensor. For example, the person detection unit 21a detects a person by sensing heat emitted by a human body in a predetermined detection area. The person detection unit 21a may also be configured to use a motion detection sensor. For example, the person detection unit 21a detects a person by sensing that something has moved in a predetermined detection area. The person detection unit 21a may also be configured to use a voice recognition sensor. For example, the person detection unit 21a detects a person by recognizing a specific keyword or phrase.

[0031] The face detection unit 21b detects the face of a person included in the detected image and acquires face information related to facial features. The face information is stored in the ROM 22a that constitutes the storage unit 22. For example, the face detection unit 21b uses an existing face recognition technology to detect the face of a person included in the detected image and acquire the face information of the person. For example, the acquired face information is stored in association with the date and time of acquisition.

[0032] The person determination unit 21c performs a search target person determination. Specifically, the person determination unit 21c determines whether or not a person included in the detected image is the search target person, based on the search target person data registered by the search requester 50. For example, if the person determination unit 21c determines that the person included in the detected image is the search target person, the base unit 2 notifies the registration device 10 via the Internet 100 that the search target person has been found.

[0033] The storage unit 22 includes a ROM 22a and a RAM 22b.

[0034] The ROM 22a is a read-only memory, and stores, for example, programs and firmware necessary for the operation of the control unit 21. The data stored in the ROM 22a is generally not erased even when the power to the parent device 2 is turned off, and therefore the ROM 22a stores data that is not normally changed. The ROM 22a may also be configured as a flash ROM, and the data stored in the ROM 22a may be rewritable.

[0035] The RAM 22b is a readable and writable memory, and stores, for example, temporary data necessary for the operation of the control unit 21, information currently being processed, etc. The data stored in the RAM 22a is generally lost when the power to the base unit 2 is turned off. The RAM 22a stores data for calculation processes executed by the control unit 21 and other temporary data for controlling various hardware components.

[0036] The handset communication I / F unit 23 is an interface that communicatively connects the base unit 2 and the handset 3. The base unit 2 communicatively connected to the handset 3 via the handset communication I / F unit 23 becomes capable of making and receiving calls with the handset 3.

[0037] The audio signal control unit 24 is electrically connected to the control unit 21, the microphone 24a, and the speaker 24b. The audio input to the microphone 24a is converted into analog audio data by the audio signal control unit 24. The speaker 24b outputs sound based on the analog audio data output from the audio signal control unit 24.

[0038] The audio signal bus 25 functions as a path for sending audio signals to the control unit 21. The control unit 21 processes the audio signals input via the audio signal bus 25. For example, the control unit 21 uses the audio signals to perform voice recognition, provide an intercom function, and store call data in the memory unit 22.

[0039] Display unit 26 displays an image based on the digital image data output from control unit 21. Display unit 26 may be a touch panel type liquid crystal display device. Display unit 26 is a user interface for displaying the status of intercom system 1 and accepting operations of base unit 2. For example, a resident can operate base unit 2 while checking the image of the visitor displayed on display unit 26 to start a call with the visitor.

[0040] The short-range wireless control unit 27 controls the wireless LAN communication I / F unit 27a. The short-range wireless control unit 27 controls wireless communication between the base unit 2 and devices with wireless communication functions that are located in a short distance from the base unit 2. For example, the short-range wireless control unit 27 controls wireless communication between an app on a smartphone in a room and the base unit 2. At that time, the base unit 2 may notify the smartphone of information about a visitor who has come to visit.

[0041] Furthermore, when the base unit 2 and the handset 3 are connected via wireless communication, the short-distance wireless control unit 27 may be configured to control the wireless communication between the base unit 2 and the handset 3.

[0042] The wireless LAN communication I / F unit 27a is an interface that communicatively connects the base unit 2 with a device having a wireless communication function. For example, the base unit 2 can be communicatively connected to an outside device installed outside the house A via wireless communication.

[0043] The wireless LAN communication unit 27b performs wireless communication in accordance with a communication standard such as Wi-Fi (registered trademark).

[0044] The wired LAN communication I / F unit 28 is an interface that communicatively connects the base unit 2 with devices having wired communication functions. For example, the base unit 2 can be communicatively connected to an external device installed outside the residence A via the Internet 100.

[0045] For example, the outside device connected to the base unit 2 may be an outside camera, a security sensor, etc. The outside camera is installed separately from the camera 34 of the handset 3 and is used to monitor areas with poor visibility and to check visitors. The video captured by the outside camera is displayed on the display unit 26. The resident views the video displayed on the display unit 26 to check the face of the visitor and the external situation. The outside camera may be configured with a moving object detection function and a night vision function. The outside camera may also be a surveillance camera or a security camera.

[0046] The security sensors are attached to the entrance, windows, garage, etc., and sound an alarm if they detect an intruder on the premises of House A. The security sensors also send a signal to an outside camera, and based on this signal, the outside camera begins capturing an image of the person detected by the security sensor.

[0047] These outside-home devices may be configured to be connectable to smartphones and personal computers, allowing for remote operation and monitoring.

[0048] Block configuration of handset 3 The block configuration of the handset 3 will be described with reference to Fig. 2. As shown in Fig. 2, the handset 3 has a control unit 31, a storage unit 32, a base unit communication I / F unit 33, a camera 34, a call button 35, a microphone 36, and a speaker 37.

[0049] The control unit 31 controls the overall operation of the slave unit 3. For example, the control unit 31 controls the transmission of a detected image captured by the camera 34 to the master unit 2.

[0050] The storage unit 32 includes a ROM 32a and a RAM 32b.

[0051] The ROM 32a is a read-only memory, and stores, for example, programs and firmware required for the operation of the control unit 31. The data stored in the ROM 32a is generally not erased even when the power to the slave unit 3 is turned off, and therefore the ROM 32a stores data that is not normally changed. The ROM 32a may also be configured as a flash ROM, and the data stored in the ROM 32a may be rewritable.

[0052] The RAM 32b is a readable and writable memory, and stores, for example, temporary data necessary for the operation of the control unit 31, information currently being processed, etc. The data stored in the RAM 32a is generally lost when the power to the slave unit 3 is turned off. The RAM 32a stores data for the calculation process executed by the control unit 31 and other temporary data for controlling various hardware components.

[0053] The base unit communication I / F unit 33 is an interface that communicatively connects the handset 3 and the base unit 2. The handset 3 communicatively connected to the base unit 2 via the base unit communication I / F unit 33 becomes capable of making and receiving calls with the base unit 2.

[0054] Camera 34 captures images of the area near the entrance of house A. As described above, camera 34 may be configured with a motion sensor, and when a person is detected in a predetermined detection area, camera 34 begins capturing an image of the person. Camera 34 is an example of an exterior camera installed outside the home.

[0055] Call button 35 is pressed, for example, by a visitor outside the home. Based on the operation of this call button 35, control unit 31 controls camera 34 to capture an image of the outside of the home. The image captured by camera 34 is displayed, for example, on display unit 26 of base unit 2.

[0056] Furthermore, when a visitor presses the call button 35, the control unit 31 controls the microphone 36 and the speaker 37. The voice input to the microphone 36 is output from the speaker 24b of the base unit 2. The speaker 37 outputs the voice input to the microphone 24a of the base unit 2.

[0057] Block configuration of the registration device 10 The block configuration of the registration device 10 will be described with reference to Fig. 3. As shown in Fig. 3, the registration device 10 includes a control unit 11, a storage unit 12, a wired LAN communication I / F unit 13, and a display unit 14.

[0058] The control unit 11 controls the overall operation of the registration device 10. The control unit 11 includes an OS processing unit 11a, an application processing unit 11b, and a person determination unit 11c.

[0059] The OS processing unit 11a controls the operating system (OS), which manages the operation, resources, etc. of the registration device 10.

[0060] The application processing unit 11b controls the operation and behavior of applications installed in the registration device 10. The application processing unit 11b controls the start-up, operation, termination, etc. of applications.

[0061] The person determination unit 11c performs a search target person determination. Specifically, the person determination unit 11c determines whether or not a person included in the detected image received from the base unit 2 is the search target person, based on the search target person data registered by the search requester 50. If the person included in the detected image is the search target person, the registration device 10 notifies the search requester 50 and the base unit 2 via the Internet 100 that the search target person has been found.

[0062] The storage unit 12 includes a ROM 12a and a RAM 12b.

[0063] The ROM 12a is a read-only memory, and stores, for example, programs and firmware necessary for the operation of the control unit 11. The data stored in the ROM 12a is generally not erased even when the power to the registration device 10 is turned off, and therefore the ROM 12a stores data that is not usually changed. The ROM 12a may also be configured as a flash ROM, and the search target person data is stored in the ROM 12a.

[0064] RAM 12b is a readable and writable memory that stores, for example, temporary data required for the operation of control unit 21, information currently being processed, etc. Data stored in RAM 12a is generally lost when the power to registration device 10 is turned off. RAM 12a stores data for calculation processing executed by control unit 11 and other temporary data for controlling various hardware components.

[0065] The wired LAN communication I / F unit 13 is an interface that communicably connects the registration device 10 with a device having a wired communication function.

[0066] The display unit 14 displays an image based on the digital image data output from the control unit 11. The display unit 14 may be a touch panel type liquid crystal display device. The display unit 14 is a user interface for displaying the status of the registration device 10 and accepting operations. For example, the display unit 14 notifies the user of errors that have occurred in the registration device 10 and accepts operation inputs such as setting changes.

[0067] <Search target data> The search target data is data based on the content provided by the search requester 50. The search target is a person who is being searched for by a searcher, such as a missing person or a wanted person (wanted person).

[0068] For example, the search requester may be a specific individual such as a family member or the police, or a member of a local community, and may be searching for the search target. Note that the search target is not limited to a person, but may also be, for example, a missing pet such as a dog or cat.

[0069] A search requester 50 registers search target person data relating to a search target person in the registration device 10. The search target person data registered in the registration device 10 is mainly image data and analysis data.

[0070] The image data is image data showing the appearance of the search target person, such as a photograph showing the face or figure of the search target person. The analysis data is data including, for example, the height, sex, age, etc. of the search target person, and is used to determine whether or not a person included in the detected image detected by the person detection unit 21a is the search target person.

[0071] The search target data may include item settings, such as person detection, face recognition, and loitering detection (suspicious person detection).

[0072] The base unit 2 may determine whether a person has entered a restricted area according to the item settings. The base unit 2 may also determine (identify) a person by facial recognition of the person included in the detected image according to the item settings. The base unit 2 may also determine whether a person included in the detected image is a suspicious person according to the item settings.

[0073] The search target person data may include notification settings. The notification settings are settings related to who should be notified of the determination result of a person included in a detected image by the base unit 2, and whether or not notification is necessary. For example, the notification settings are set by the search requester 50.

[0074] If the notification setting is "required," for example, when an elderly person or child who is late returning home or a missing pet is found, the base unit 2 notifies the user U that the person being searched for has been found.

[0075] If the notification setting is "unnecessary," for example, when a wanted person is found or when a search target is found for which the search requester 50 wants to keep the search a secret for some reason, the base unit 2 does not notify the user U that the search target has been found.

[0076] In addition, there are cases where the search requester 50 directly operates the registration device 10 to register the search target person data, or where the search requester 50 requests a third party (for example, an administrator who manages the registration device 10) to register the search target person data, and the third party who is requested to register the search target person data in the registration device 10.

[0077] The registration device 10 transmits the registered search target person data to the base device 2. The registration device 10 may be configured to send a push notification to the base device 2 to notify the base device 2 of the start of transmission of the search target person data, and transmit the search target person data with permission from the user U who operates the base device 2.

[0078] Furthermore, the registration device 10 may be configured to periodically transmit the search target person data to the base device 2 without obtaining permission from the user U who operates the base device 2. Furthermore, the registration device 10 may be configured to transmit the search target person data to the base device 2 when a request to transmit the search target person data is received from the base device 2.

[0079] Furthermore, the user U can operate the base unit 2 to add a determination target setting to the search target person data received by the base unit 2. The user U operates the base unit 2 to set whether or not to perform search target person determination for a person included in the detected image. For example, since the user U does not need to perform search target person determination for family members or acquaintances of the user U, when such a person is included in the detected image, the base unit 2 is set not to perform search target person determination.

[0080] When the determination target setting is "no determination required," the parent unit 2 does not perform search target person determination for people included in the detected image. When the determination target setting is "determination required," the parent unit 2 performs search target person determination for people included in the detected image.

[0081] <Search target determination> Search target person determination according to the first embodiment In the search target person determination according to the first embodiment, the master unit 2 receives search target person data registered in the registration device 10 and determines whether or not a person P included in the detected image is a search target person based on the received search target person data. If the person P is a search target person, the master unit 2 notifies the registration device 10 that the person P is a search target person, but does not notify the user U. On the other hand, if the person P is not a search target person, the master unit 2 notifies the user U that the person P is not a search target person, but does not notify the registration device 10.

[0082] Search target person determination according to the first embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the operation of the master unit 2 in search target person determination according to the first embodiment. This flow starts when the master unit 2 has completed receiving search target person data from the registration device 10 and the person detection unit 21a of the master unit 2 has detected a person P.

[0083] The master unit 2 determines whether the detected person P is a search target person based on the search target person data received from the registration device 10 (S1). If the master unit 2 determines that the person P is a search target person (YES in S1), the master unit 2 notifies the registration device 10 of the determination result that the person P is a search target person (S2), and this flow ends.

[0084] For example, in the process of S2, the registration device 10 displays a detected image including the person P on the display unit 14. The registration device 10 may also notify the search requester 50 that the person P is a person to be searched for (that the person to be searched for has been found).

[0085] If the master unit 2 determines that the person P is not a search target (NO in S1), the master unit 2 displays a detected image including the person P on the display unit 26 (S3), and this flow ends.

[0086] With this configuration, when the base unit 2 determines that person P included in the detected image is a person to be searched for, the base unit 2 does not display the detected image including person P on the display unit 26. Since the user U does not see person P determined to be a person to be searched for, for example, if person P is a wanted person, the base unit 2 can reduce the psychological burden on the user U.

[0087] Search target person determination according to the second embodiment In the search target person determination in the second embodiment, unlike the search target person determination in the first embodiment, the parent unit 2 notifies the user that person P included in the detected image is the search target person based on the notification settings included in the search target person data.

[0088] If the notification setting is "required," the base unit 2 notifies the user U that person P is a search target. On the other hand, if the setting is "not required," the base unit 2 does not notify the user U that person P is a search target.

[0089] Search target person determination according to the second embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of the operation of the master unit 2 in search target person determination according to the second embodiment. This flow starts when the master unit 2 has completed receiving search target person data from the registration device 10 and the person detection unit 21a of the master unit 2 has detected a person P.

[0090] The master unit 2 determines whether the detected person P is a search target person based on the search target person data received from the registration device 10 (S21). If the master unit 2 determines that the person P is not a search target person (NO in S21), this flow ends.

[0091] When the base unit 2 determines that the person P is a search target (YES in S21), it determines whether the notification setting included in the search target data is "required" (S22).

[0092] If the parent unit 2 determines that the notification setting included in the search target person data is "required" (YES in S22), the parent unit 2 displays a detected image including person P on the display unit 26 (S23) and proceeds to processing in S24.

[0093] If the parent unit 2 determines that the notification setting included in the search target person data is not "required" (NO in S22), that is, if the notification setting is "not required," the parent unit 2 notifies the registration device 10 of the determination result that person P is the search target person (S24), and this flow ends.

[0094] For example, in the processing of S24, the registration device 10 displays a detected image including the person P on the display unit 14. In addition, the registration device 10 may notify the search requester 50 that the person P is a person to be searched for (that the person to be searched for has been found).

[0095] With this configuration, when the base unit 2 determines that person P included in the detected image is a person to be searched for, it displays the detected image including person P on the display unit 26 based on the notification setting. For example, if person P is a missing person that people in the community are searching for, the user U can cooperate in the search by looking at person P displayed by the base unit 2. Furthermore, if person P displayed by the base unit 2 is a wanted person, the base unit 2 can be set not to display person P, thereby reducing the psychological burden on the user U.

[0096] Search target person determination according to the third embodiment Unlike the search target person determination according to the first embodiment, the search target person determination according to the third embodiment is performed by the control unit 11 (person determination unit 11c) of the registration device 10. The parent device 2 transmits a detected image including person P to the registration device 10 based on the determination target setting. The person determination unit 11c determines whether person P included in the detected image is a search target person based on the search target person data.

[0097] Search target person determination according to the third embodiment will be described with reference to Fig. 6. Fig. 6 is a sequence chart showing an example of the operations of the master device 2 and the registration device 10 in search target person determination according to the third embodiment.

[0098] The parent unit 2 determines whether the determination target setting of the person P included in the detected image is "determination required" (S31). If the parent unit 2 determines that the determination target setting of the person P included in the detected image is "determination not required" (NO in S31), the sequence of the parent unit 2 ends.

[0099] If the parent unit 2 determines that the judgment target setting for the person P included in the detected image is "judgment required" (YES in S31), the parent unit 2 transmits the detected image including the person P to the registration device 10 (S32).

[0100] The registration device 10 refers to the search target person data and determines whether or not the person P included in the detected image received from the base device 2 is a search target person (S33).

[0101] If the registration device 10 determines that the person P included in the detected image is not a search target (NO in S33), the registration device 10 notifies the parent device 2 of the determination result that the person P is not a search target (S34).

[0102] Upon receiving notification of the determination result that person P is not the person being searched for, parent unit 2 displays the detected image including person P on display unit 26 (first display unit) (S35), and the sequence of parent unit 2 ends.

[0103] If the registration device 10 determines that the person P included in the detected image is the person being searched for (YES in S33), the registration device 10 displays the detected image including the person P on the display unit 14 (second display unit) (S36), and the sequence of the registration device 10 ends.

[0104] In the process of S36, the registration device 10 may notify the search requester 50 that the person P is a person to be searched for (that the person to be searched for has been found).

[0105] With this configuration, the parent device 2 does not need to store the search target person data, which can save storage (for example, memory unit 22) of the parent device 2. Furthermore, the registration device 10 determines whether the person P included in the detected image is a search target person, which can reduce the burden on the parent device 2 (for example, control unit 21 of the parent device 2).

[0106] Furthermore, the parent device 2 transmits a detected image including the person P based on the determination target setting to the registration device 10. Therefore, if the detected person P includes a family member or acquaintance of the user U, the privacy of the person P can be taken into consideration.

[0107] Search target person determination according to the fourth embodiment In the search target person determination according to the fourth embodiment, unlike the search target person determination according to the second embodiment, the search target person determination is performed by the control unit 11 (person determination unit 11c) of the registration device 10. The parent device 2 transmits a detected image including person P to the registration device 10 based on the determination target setting. The person determination unit 11c determines whether person P included in the detected image is a search target person based on the search target person data. The registration device 10 notifies that person P included in the detected image is a search target person based on the notification setting included in the search target person data.

[0108] If the notification setting is "required", the registration device 10 notifies the base unit 2 that the person P is a search target. On the other hand, if the setting is "not required", the registration device 10 does not notify the base unit 2 that the person P is a search target.

[0109] Search target person determination according to the fourth embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of the operation of the registration device 10 in search target person determination according to the fourth embodiment.

[0110] The processes of S31 and S32 are the same as those in Fig. 6, and therefore will not be described here. Compared to the flow in Fig. 6, the flow in Fig. 7 executes processes of S41 to S45 instead of the processes of S33 to S36.

[0111] The master device 2 transmits a detected image including the person P to the registration device 10 (S32).

[0112] The registration device 10 refers to the search target person data and determines whether or not the person P included in the detected image received from the base device 2 is a search target person (S41).

[0113] If the registration device 10 determines that the person P included in the detected image is not a search target (NO in S41), the sequence of the registration device 10 ends.

[0114] When the registration device 10 determines that the person P included in the detected image is a search target person (YES in S41), the registration device 10 determines whether the notification setting included in the search target person data is "required" (S42).

[0115] If the registration device 10 determines that the notification setting included in the search target person data is "required" (YES in S42), the registration device 10 notifies the parent device 2 of the determination result that the person P included in the detected image is the search target person (S43).

[0116] Upon receiving the notification of the determination result that person P is the person to be searched for, the master unit 2 displays the detected image including person P on the display unit 26 (S44), and the sequence of the master unit 2 ends.

[0117] If the answer is YES in S42, the registration device 10 displays the detected image including the person P on the display unit 14 (S45), and the sequence of the registration device 10 ends.

[0118] In the process of S45, the registration device 10 may notify the search requester 50 that the person P is the person to be searched for (that the person to be searched for has been found).

[0119] With this configuration, when the registration device 10 determines that the person P included in the detected image is the search target person, the registration device 10 notifies the base unit 2 of the determination result that the person P is the search target person based on the notification setting. Since the registration device 10 does not notify the base unit 2 of unnecessary determination results, it is possible to reduce the psychological burden on the user U.

[0120] <Summary of the embodiment> As described above, the intercom master unit 2 of this embodiment comprises a person detection unit 21a that detects a person included in a detection image captured by the camera 34 of the intercom slave unit 3, a display unit 26 that displays the detection image, a wired LAN communication I / F unit 28 that communicates with the registration device 10 in which the search target person data is registered, and a person determination unit 21c that determines whether or not the person is a search target person based on the search target person data received from the registration device 10, and if the person determination unit 21c determines that the person is a search target person, it notifies the registration device 10 that the person is a search target person.

[0121] The intercom master unit 2 of this embodiment includes a person detection unit 21a that detects a person included in a detected image captured by a camera 34 installed outside the home, a display unit 26 that displays the detected image, and a wired LAN communication I / F unit 28 that transmits the detected image to a registration device 10 in which search target person data is registered. The registration device 10 includes a person determination unit 13c that determines whether or not a person included in the received detected image is a search target person based on the search target person data. and a display unit 14 that displays the detected image, and when the person determination unit 13c determines that the person is a search target person, the display unit 14 displays the detected image.

[0122] With this configuration, when the parent unit 2 determines that the person P included in the detected image is the person being searched for, the parent unit 2 does not display the detected image including the person P on the display unit 26. Because the user U does not see the person P determined to be the person being searched for, the parent unit 2 can reduce the psychological burden on the user U.

[0123] Furthermore, if person P is determined to be a search target, base unit 2 can notify user U of the determination result that person P is a search target based on the notification settings. For example, base unit 2 can flexibly handle information about search targets, such as not notifying user U if person P is a wanted person sought by the police, or notifying user U if person P is a missing person sought by local residents. This allows base unit 2 to notify user U that the search target has been found while minimizing the psychological burden on user U.

[0124] The determination result of the search target determination of the person P may be notified to a party other than the registration device 10 and the user U. For example, the determination result may be notified to a local police station, fire department, or security company.

[0125] It should be noted that this embodiment can be applied not only to the intercom system 1 but also to a security system having a monitoring camera or a security camera, for example. A security system to which this embodiment is applied can be used as a search target person determination device that determines a search target person.
