In order to prevent crimes and detect abnormalities early, security guards etc. have regularly implemented measures to circulate through the prescribed locations. However, there were the following problems in the creation of history by patrolmen.
One is that the history is left by a paper medium or a personal computer. For example, the implementation check may be falsified if the tour is performed three times even though the tour is performed only twice. In addition, even if a tour of two people was obligated, there was a falsification in which only one person actually visited and was recorded as two on the record.
In order to prevent such tampering, there is a device that records an accurate traveling history, but it becomes a dedicated device and the cost is increased.

  On the other hand, an intercom system that can connect intercom slave units and interphone master units via a communication network can be easily installed at low cost in the security target area because the installation range is limited and the number of connected units is also flexible. Installation is progressing because it is effective in improving security such as reporting of abnormalities.

  Accordingly, in view of the above-mentioned problem of patrol history alteration, the present invention provides an interphone system that enables record creation by operating an interphone slave installed at a patrol destination and prevents tampering. It is aimed.

In order to solve the above problems, the invention of claim 1 is directed to a camera for imaging an operator, at least one intercom slave having a calling / calling function, a monitor for displaying an image captured by the camera, and an intercom slave. Interphone system connected via intercommunication network with interphone master unit equipped with call function that responds by receiving call from device, server communicating with video information storage unit for storing captured video of camera communicates The interphone slave unit is connected via a network and has a call control unit that performs two operations of a call operation and a registration operation. The call operation is performed in response to a predetermined call operation. While at least a call signal is transmitted among the call signal and the captured image of the camera, the registration operation is performed in response to a predetermined registration operation, It transmits a call signal and the camera captured image of the over server, server call signal and captured image is transmitted, characterized by storing the image information storage unit together with time and date information captured video received.
According to this configuration, when a security guard or the like patrols a predetermined place, the patrol history can be left in the server by operating the interphone handset installed in the patrol place. Therefore, there is no room for falsification of the history, and the video information is included in the history, so that the number of patrols can be grasped and it is possible to prevent the patrol from becoming sparse. And it is not necessary to create a separate tour record after the tour.

According to the second aspect of the present invention, at least one interphone slave unit having a camera for capturing an image of an operator and a calling / calling function, a monitor for displaying an image captured by the camera, and a call from the interphone slave unit responds to the call.

The call operation is performed in response to a predetermined call operation. Both of them send a call signal, while the registration operation is performed in response to a predetermined registration operation, and the call signal and data-converted image of the camera are transmitted to the surveillance camera recording device, and the captured image is sent to the surveillance camera recording device. It is stored with information.
According to this configuration, when a guard or the like patrols a predetermined place, the patrol history can be left in the surveillance camera recording device by operating the interphone slave unit installed in the patrol place. Therefore, there is no room for falsification of the history, and the video information is included in the history, so that the number of patrols can be grasped and it is possible to prevent the patrol from becoming sparse. And it is not necessary to create a separate tour record after the tour. In addition, since the history is stored in the monitoring camera recording device, the recorded video can be managed together with the video of the monitoring camera, and it is not necessary to provide a separate history storage means, and can be implemented with an inexpensive configuration.

According to a third aspect of the present invention, in the configuration according to the first or second aspect, the intercom handset has a call button for pressing to perform a call operation, and the call control unit continues the call button for a predetermined time or more. When the button is pressed, it is determined that a registration operation has been performed, and a registration operation is started.
According to this configuration, since the registration operation can be performed by operating the call button, it is sufficient to provide one call button in the interphone slave unit, which can be used without changing the conventional interphone slave unit, and can be configured at low cost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an example of an intercom system according to the present invention, and shows devices in a circuit block diagram. Reference numeral 1 denotes a camera 11 for capturing an image of an operator and an interphone slave unit having a calling / calling function (hereinafter, simply referred to as “slave unit”), and 2 denotes a monitor 21 and a slave unit that display images captured by the camera 11 An interphone master unit (hereinafter simply referred to as “master unit”) having a call function for receiving a call from 1 and responding thereto is a server that stores a captured image of the camera 11. At least one child device 1 and one parent device 2 are installed, and each device is connected to each other via a communication network N such as a LAN or the Internet.
In addition, the subunit | mobile_unit 1 is installed in the place where a guard patrols, for example, and the main | base station 2 and the server 3 are installed in a security company etc. For example, the subunit | mobile_unit 1 is installed in the place which stops in patrols, such as a park, an event hall, an office building, and a coin parking.

  In addition to the camera 11, the handset 1 performs a call button 12 for performing both a call operation and a registration operation described later, a microphone 13 and a speaker 14 for making a call, and A / D / D / A conversion of an audio signal. Communication with the audio processing unit 15, the video processing unit 16 that performs modulation of the video signal, the memory 17 that temporarily stores the captured video of the camera 11, the slave CPU 18 that controls the slave 1, the master 2, and the server 3. A slave communication IF 19 to be implemented is provided.

The base unit 2 includes a monitor 21 for displaying video, a handset 22 for responding, a speaker 23 for calling and reporting, an audio processing unit for performing A / D / D / A conversion of audio signals, etc. 24, a video processing unit 25 for demodulating a video signal, a parent CPU 26 for controlling the parent device 2, a parent device communication IF 27 for communicating with the child device 1 and the server 3, and the like.
The server 3 includes a video storage unit 31 that stores video, a server CPU 32 that controls the server 3, a server IF 33 that communicates with the slave unit 1 and the master unit 2, and the like.

  The operation of the intercom system configured as described above is as follows. As described above, the call operation and the registration operation can be performed by operating the call button 12. First, the registration operation will be described. The registration operation is an operation of recording the video of the person who operated the handset 1 and the operated date and time information in the server 3 and leaving a history, and pressing the call button 12 continuously for a predetermined time (for example, 2 seconds or more). It is carried out by doing. Hereinafter, this will be described as “long press”.

The slave CPU 18 recognizes that the registration operation has been performed when the call button 12 is pressed for a long time, notifies the registration operation from the speaker 14 by an announcement or the like, and notifies the server 3 of the call signal and the captured image of the camera 11. Send.
Specifically, the slave CPU 18 activates the camera 11 when the call button 12 is pressed, records the captured image in the memory 17 and temporarily stores it. This recording is continued until the pressing of the call button 12 is finished, and the recording is also finished when the long press of the call button 12 is finished. As a result, an image of 2 seconds or longer is stored in the memory 17. If the pressing time of the call button 12 does not reach the predetermined time, it is determined that the call operation has been performed, a call operation described later is performed, and the image recorded in the memory 17 is erased.

After long pressing in this way, the video stored in the memory 17 is transmitted to the server 3 together with the calling signal. The call signal and video are transmitted to the server 3 via the communication network N.
Receiving the call signal and video, the server CPU 32 stores the ID information of the slave unit 1 and the received video included in the call signal in the video storage unit 31 together with the received time information.

On the other hand, when the call button 12 is pressed but not pressed for a long time, the call operation is performed. If the pressing duration time does not reach the predetermined time, handset CPU 18 determines that a call operation has been performed and starts a call operation. In the call operation, a call signal is generated and transmitted to the parent device 2, and an image captured by the camera 11 is transmitted to the parent device 2.
In the base unit 2 that has received the call signal and the video via the communication network N, the base unit CPU 26 reports the ringing sound from the speaker 23 and displays the transmitted video on the monitor 21.
Thus, when the responder who notices the ringing tone of the main unit 2 picks up the handset 22, a call path is formed and a call is made between the caller and the responder.

In this way, when a security guard or the like patrols a predetermined place, the visit history can be left in the server 3 by performing a predetermined registration operation on the handset 1 installed at the patrol place. Therefore, there is no room for falsification of the history, and the video information is included in the history, so that the number of patrols can be grasped and it is possible to prevent the patrol from becoming sparse. And it is not necessary to create a separate tour record after the tour.
Further, since the registration operation can also be performed by operating the call button 12, it is only necessary to provide the caller 12 with one call button 12, which can be used without changing the conventional slave unit and can be configured at low cost.
Furthermore, since the video during the registration operation is stored, the video of the operator can be recorded reliably, and since the file containing the video is transmitted after the registration operation is completed, the transmission speed may be reduced. It is also possible to increase the resolution. Furthermore, since error retry is possible, reliable recording can be performed.

FIG. 2 is a schematic configuration diagram showing another form of the intercom system. Next, another form will be described with reference to FIG. The recording destination that is implemented in response to the registration operation is different from that shown in FIG. 1 and is configured to record on the surveillance camera recording device 4 for recording the captured video of the surveillance camera. In the following, components that are the same as those in FIG.
The connection form of the child device 1 and the parent device 2 is the same as that in FIG. 1, and the surveillance camera recording device 4 is also connected to the child device 1 and the parent device 2 via the communication network N as in the server 3. Note that the surveillance camera that is originally recorded by the surveillance camera recording device 4 is omitted.

  The subunit | mobile_unit 1 has the image | video process part 16a which carries out data conversion of the video signal which the camera 11 outputs into the video data which the monitoring camera recording device 4 can record, and the image | video by which data conversion was carried out is output. On the other hand, the master unit 2 includes a video processing unit 25a that generates a video to be displayed on the monitor 21 by returning the video signal transmitted from the slave unit 1 to the original data.

  The monitoring camera recording device 4 includes a video storage unit 41 that stores video, a recording device CPU 42 that controls the monitoring camera recording device, a recording device IF 43 that communicates with the slave unit 1 and the master unit 2, and the like.

The basic operation of the intercom system configured as described above is the same as that in the above embodiment. When a call operation is performed, the base unit 2 is called and a response operation is performed, thereby forming a communication path. When the call button 12 is pressed and registered, the captured image of the camera 11 is recorded in the memory 17 under the control of the slave CPU 18, and when the call button 12 is long pressed, the recording is terminated and the call signal is displayed. The recorded video is transmitted to the surveillance camera recording device 4.
The monitoring camera recording device 4 that has received the call signal and the video stores the ID information and video of the slave unit 1 included in the call signal in the video storage unit 41 together with the received time information.

Here, the video signal will be described. As described above, the video signal that can be recorded by the surveillance camera recording device 4 is an output signal form of the surveillance camera, and the format is different from the signal output by the interphone camera. The video signal output from the camera 11 is normally an NTSC analog signal, which is A / D converted and transmitted to the parent device 2 and the server 3 (the form shown in FIG. 1). On the other hand, the surveillance camera recording device 4 is one of the video compression encoding systems in accordance with the video signal output from the surveillance camera. The video compressed in the H.264 format is saved.
Therefore, the video signal output from the camera 11 of the slave unit 1 can also be recorded in the video processing unit 16a by the H.V. It is converted into the H.264 format and output.

  In addition, in the base unit 2, in order to display the video received from the handset 1 and the video recorded by the surveillance camera recording device 4 on the monitor 21, the video processing unit 25 a performs H.264. H.264 video data is converted into an NTSC signal, and a video that can be displayed on the monitor 21 is generated.

In this way, when a security guard or the like patrols a predetermined place, the patrol history can be left in the surveillance camera recording device 4 by operating the handset 1 installed at the patrol place. For this reason, there is no room for falsification of the history. In addition, since the video information is included in the history, the number of patrols can be grasped, and the patrol can be prevented from becoming sparse. And it is not necessary to create a separate tour record after the tour.
In addition, since the history is stored in the monitoring camera recording device 4, the recorded video can be managed together with the video of the monitoring camera, and it is not necessary to provide a separate history storage means, and can be implemented with an inexpensive configuration.

In each of the above embodiments, the video temporarily recorded in the slave unit 1 is transmitted to the server 3 or the monitoring camera recording device 4. However, the slave unit 1 is not provided with the memory 17 and may be directly transmitted. good. For example, the call operation / registration operation is determined at the end of the pressing operation of the call button 12, and if it is not a long press, the call control is started, and if it is a long press, the slave CPU 18 is controlled to start the registration control. That's fine. Even if it controls in this way, since the operator who operated the call button 12 at least at the start of imaging can be imaged, it can be used as history data. Then, the video transmission may be terminated when a certain time (for example, 5 seconds) elapses.
In addition, the call button 12 may be dedicated to calling and a dedicated registration button may be provided.
