  The camera server 4 is configured as shown in FIG. FIG. 4 is a circuit block diagram of the camera server 4. The recording unit 41 records video data and audio data, the video processing unit 42 performs data processing of recorded video and reproduced video, and the recorded audio and reproduced audio. An audio processing unit 43 that performs data processing, a server CPU 44 that controls the camera server 4, a server communication interface (server communication IF) 45 for communicating with the WEB camera 3 and the like via a LAN using a general-purpose network protocol such as TCP / IP It has.

  The front door 1, the WEB camera 3, and the camera server 4 each have a time adjustment function such as NTP, and when the camera server 4 records, the time stamps of audio and video are recorded in alignment.

The intercom system configured as described above operates as follows. When a visitor performs a call operation by operating the call button 11 of the entrance handset 1, a call signal is transmitted from the handset communication IF 15 to the living room base unit 2 via the HUB 5, and the WEB camera 3 and the camera server 4. Is activated.
Further, in the entrance handset 1 that has received the calling operation, a microphone (not shown) of the camera 12 and the calling unit 13 is activated, the camera 12 starts imaging and outputs an image, and a sound (voice) that is picked up by the microphone. Is output. The video data and audio data output in this way are transmitted to the room base unit 2 and the camera server 4 with the time stamp added by the handset communication IF 15.

  Upon receiving the call signal, the room master unit 2 reports a ring tone from a speaker (not shown) of the call unit 22 under the control of the base unit CPU 26 and displays the received video data on the monitor 23. When the call button 21 of the room base unit 2 is operated by the resident in response to this ringing tone, a call path is formed between the room base unit 2 and the entrance unit 1, and the resident displays on the monitor 23. You can make a call with the visitor while confirming the visitor with the video.

  On the other hand, the WEB camera 3 that has received the activation signal starts imaging and transmits video data with a time stamp to the camera server 4. Also, the camera server 4 that has received the activation signal receives the video data and audio data transmitted from the front door unit 1 under the control of the server CPU 44 and the video signal transmitted from the WEB camera 3 together with a time stamp, The audio data and the video data are integrated and recorded in the recording unit 41 so that the time stamps coincide with each other. In this way, the recording operation of the camera server 4 is performed regardless of the presence or absence of a response operation of the living room master unit 2, and the recording operation is terminated when a predetermined time has elapsed.

Note that “integrated” not only records audio data and video data together in one file (recording unit) but also compares the sequence number of the received file with a time stamp, It also includes a method of recording in a plurality of files such as creating an index file so that the audio signal and the video signal do not shift.
When a plurality of WEB cameras 3 are provided, an activation signal is transmitted from the entrance cordless handset 1 to all the WEB cameras 3 so that the camera server 4 similarly records images taken by individual WEB cameras. It is possible.

The reproduction operation of the audio data and the video data thus recorded is performed by the operation of the living room master unit 2. Specifically, when the operation unit 25 of the living room base unit 2 is subjected to a predetermined playback operation, a playback request signal is sent from the living room base unit 2 to the camera server 4. The camera server 4 that has received the reproduction request signal extracts the video data (one video data selected by the operation unit 25) and the audio data recorded by the server CPU 44 in the recording unit 41 together with the time stamp, and the room base unit 2 Send to.
The room base unit 2 that has obtained the video data and the voice data displays the video on the monitor 23 under the control of the base unit CPU 26, and the sound is reported from the speaker of the calling unit 22. At this time, the master CPU 26 controls reproduction by matching the time stamps of the video and audio.

  On the other hand, when the human sensor 14 performs a sensing operation, it operates as follows. The human sensor 14 is provided to detect a suspicious person, and a built-in timer outputs a detection signal when it continues to detect the approach of a person for a certain period of time. When the sensing signal is output, an activation signal is sent from the handset communication IF 15 to the WEB camera 3 and the camera server 4 in the same manner as when the call operation is received. In addition, the voice collected when the microphone of the calling unit 13 is activated is transmitted to the camera server 4.

  Upon receiving the activation signal, the WEB camera 3 starts imaging and transmits the video data to the camera server 4. Upon receiving the activation signal, the camera server 4 integrates the video data captured by the WEB camera 3 and the audio data transmitted from the front door 1 such that the time stamps coincide with each other and records the integrated data in the recording unit 41. . However, if the camera server 4 has already recorded by operating the call button 11 or the like, the signal is ignored even if a new activation signal is transmitted.

In this way, in response to a call operation from the entrance slave unit 1, the video captured by the WEB camera 3 and the sound collected by the entrance slave unit 1 are recorded in the camera server 4. Therefore, since recording and recording are performed without going through the living room parent device 2, it is not necessary to provide the living room parent device 2 with a function of recording by communicating with the WEB camera 3, and the cost of the living room parent device 2 can be prevented. In addition, since recording and recording are performed regardless of the presence / absence of a response operation of the room master unit 2, convenience and crime prevention can be improved.
In addition, since the video captured by the front door unit 1 is also recorded on the camera server 4, the face of the visitor can be confirmed by reproducing the recording of the camera server 4, and the visitor when absent can be confirmed. And since the record of the visitor who responded remains, convenience and crime prevention can be improved.
Further, since the video and audio recorded in the camera server 4 by the operation of the room master unit 2 can be confirmed in the room base unit 2, the recorded video and audio can be recorded without directly operating the camera server 4. It can be confirmed and is convenient.
In addition, since the captured image of the WEB camera 3 and the collected sound of the entrance unit 1 are recorded so that there is no time lag, the recorded video and the sound are matched even if the imaging device and the collected sound device are different. So that there is no sense of incongruity during playback.
Further, even when the human sensor 14 performs a sensing operation, the video of the WEB camera 3 is recorded and the voice picked up by the front door 1 is recorded. Therefore, the video of the suspicious person who does not press the call button 11 is recorded as voice. It can be recorded together and the security function is improved.

In the above embodiment, the devices are arranged inside and outside the same building. However, the present invention is not limited to this. For example, the camera server 4 can be installed in a remote data center or a server in a provider. Only the reception function and the synthesis function of the server 4 can be installed indoors, and only the storage unit (recording unit) for storage can be installed in a server in the data center or provider. Furthermore, although the WEB camera 3 and the camera server 4 are separated, these may be integrated.
Further, the camera server 4 itself may be provided with a monitor and a speaker so that the recorded video and audio can be reproduced. In this case, even if the living room master unit 2 does not have a function of communicating with the camera server 4, it is possible to reproduce and check the recorded video and audio.
Furthermore, although each device is connected by wire, it may be a wireless connection such as a wireless LAN.
