Send a signal. The video signal is
The signal is transmitted by the line terminal 5 to the telephone network 10 through the antenna 40, and reaches the portable terminal 6 separately from the voice signal through an existing packet network, the Internet, or a circuit switching network having immediacy, for example, as shown in FIG.

Here, the connection between the common entrance apparatus 11 and the portable terminal 6 may be a constant connection or a dial-up connection. When the connection is made using the Internet, the video signal can be distributed to each portable terminal 6 via the designated server. Further, the audio signal is transmitted through the same telephone network as when an ordinary audio signal is transmitted / received, and if a different route from the video signal for packet communication is used, no burden is imposed on the packet communication.

When a video signal addressed to the own device is transmitted, the monitor 6a of the portable terminal 6 displays the video on the screen. Therefore, in each mobile terminal 6, an image is displayed on the monitor 6 a, and it can be known that the call is from the intercom 4. Each resident possessing the mobile terminal 6 can make a call with the collective intercom 4 by pressing the call button of the mobile terminal 6 or the like to set the mobile terminal 6 in an off-hook state.

On the other hand, when the portable terminal 6 is in the off-hook state, the inversion detecting unit 17 detects the polarity inversion due to the off-hook of the portable terminal 6 and notifies the control unit 15 of it. The DTMF detection unit 19 monitors the DTMF signal on the line,
When a signal is detected, a detection signal is output to the control unit 15. When receiving the detection signal from the DTMF detection unit 19 while the inversion notification from the inversion detection unit 17 is being input, the control unit 15 performs the unlock control operation. Even if the detection signal is input from the DTMF detection unit 19, the inversion detection unit 17
If there is no reversal notification from, the unlock control operation is not performed. Therefore, even if the DTMF detection unit 19 detects the DTMF signal during the calling or the end of the call, the unlock control operation is not performed.

When receiving the detection signal from the DTMF detection unit 19 while receiving the inversion notification from the inversion detection unit 17, the control unit 15 determines whether the DTMF signal matches a predetermined signal. Then, the control unit 15 issues an unlocking command for the electronic lock 8 when the detected DTMF signal matches the predetermined signal. The unlock signal generated by the portable terminal 6 is transmitted through a packet communication network, the Internet, or a circuit switching network, like the video signal.

As described above, in the security system 1 for an apartment house according to the present embodiment, the existing telephone network 1 is used.
In addition, by using the two signal systems of the audio system and the video system as separate routes while using 0, the telephone network 1 is used in each dwelling unit.
A visitor can be handled by using the general-purpose portable terminal 6 that can be connected to the terminal 0, and a dedicated communication device is not required. Of course, for video systems, instant communication using a packet network or the Internet is ensured.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, another service may be added to the security system 1 for an apartment house of the present embodiment as described below.

That is, in this embodiment, when transmitting a video signal or the like via the Internet and a designated server, the video signal is directly delivered to the resident's portable terminal 6, but as shown in FIG. May be interposed. For example, a secretary service digitally processes information distributed as audio, video, and video, adds individual management data, stores it as data, and responds mechanically in response to visits made in the past by subscribers' instructions. (For example, data processing by a computer) or a personal response by a secretary. On the other hand, the management service is always connected to the Internet, and if the connection is lost, it is judged as an abnormal situation and some action is taken, such as contacting an apartment management company, security company, police, etc. .

In this embodiment, the camera 9 is provided on the collective intercom 4 for convenience. However, the camera 9 does not necessarily have to be integrated with the collective intercom 4, and as shown in FIG. It may be provided.

For the transmission of the two signal systems of the audio system and the video system, it is preferable to use separate routes as described above, but these can also be transmitted on the same route.

In the present embodiment, signals are transmitted using the existing telephone network 10. The telephone network 10 is a telephone network formed by a high-speed optical communication network that is currently being developed. Etc. are included.
