Further, a resident in the room carrying the mobile terminal 4 can make a call while checking the video of the visitor on the display unit 43 of the mobile terminal 4.

  In the interphone systems 1 and 10 described above, the base station connection line L3 is connected to a plurality of wireless access points 6 and is transmitted by a LAN communication protocol. However, the exchange connection line L2 is an intercom system for a detached house. In the case of 1, the exchange 5 and the living room master unit 3 are connected. In the case of the collective housing intercom system 10, only the exchange 5 and the controller 9 are connected. Therefore, either a communication protocol for LAN or a dedicated protocol may be used. . In this case, when the exchange connection line L2 is a dedicated protocol, the exchange 5 is provided with a protocol conversion function.

  Moreover, in the intercom system 1 for detached houses described above, the exchange 5 and the living room master 3 are installed separately, but the exchange 5 may be incorporated in the living room parent 3. As a result, the cable can be saved, and the number of devices is reduced by one, which has an aesthetic effect as well as simplification of the system.

  In the interphone systems 1 and 10 described above, the wireless access point 6 and the exchange 5, the living room master unit 3 and the entrance cordless handset 2 are installed separately. However, the wireless access point 6 is connected to the exchange 5, the living room master unit 3 or the entrance. You may incorporate in the at least 1 of the subunit | mobile_unit 2. FIG. As a result, it is possible to reduce the line of the LAN cable, and there is an aesthetic effect as well as simplification of the system by reducing one device.

  In the interphone systems 1 and 10 described above, the wireless access point 6 communicates wirelessly with devices having a wireless LAN function such as a network camera, personal computer, and modem. However, if the network camera, personal computer, modem, or the like does not have a wireless LAN function, it is necessary to perform wired communication, so the wireless access point 6 may be provided with a hub 61. As a result, the number of devices that can be connected to the wireless access point 6 is further increased, and the wireless access points can be easily connected to each other, thereby increasing the degree of freedom of wiring. Further, a modem 12 for carrying or arranging the portable terminal 4 outside the room may be connected to the hub 61. As a result, even when the mobile terminal 4 that is an IP mobile phone is taken out, the mobile terminal 4 can communicate with the mobile terminal 4 via a wide area network such as the Internet if the destination has a wireless LAN environment. Even if the portable terminal 4 is taken outdoors, a call can be made in response to a call from the front door 2. If the modem has a wireless LAN function, signals can be transmitted to and received from the wireless access point 6, so that the same effect as when the modem 12 is connected to the hub 61 can be obtained. Conventionally, there has been such a system using a PHS, a mobile phone, etc., but in this embodiment, by using the mobile terminal 4 which is an IP mobile phone, a low-cost system that does not require a usage fee is used. Can be realized.

  In the intercom systems 1 and 10, since the wireless access point 6 has the wireless LAN function, it is possible to connect devices having various wireless LAN functions. For example, when the modem 12 is connected to the hub 61 provided in the wireless access point 6, a resident may connect a laptop computer to the wireless access point 6 and watch the movie while downloading it on the Internet. It is done. However, if such use is performed in a plurality of rooms at the same time, there is a problem in that the line utilization rate increases and the intercom signal transmission is hindered. Therefore, when the line usage rate of the wireless access point 6 is constantly monitored by the first control function of the control unit 35 of the living room base unit 3 or the control unit 45 of the portable terminal 4 and the line usage rate exceeds a certain threshold value. , A LAN line congestion warning is displayed on the display unit 33 of the living room master unit 3 or the display unit 43 of the portable terminal 4. When the resident who sees this stops the use of the notebook personal computer, the signal transmission of the entrance cordless handset 4 can be stabilized.

  In addition, since the intercom systems 1 and 10 include the wireless LAN function in the wireless access point 6, there is a problem in that it is possible to connect to the wireless access point 6 without permission from a neighboring device outside the living room, for example, a laptop computer in a neighbor. . Therefore, the IP addresses of the connected devices are collected by the second control function of the control unit 35 of the living room base unit 3 or the control unit 45 of the mobile terminal 4, and the display unit 33 of the living room base unit 3 or the mobile terminal 4 A list of connection states can be displayed on the display unit 43. Further, the IP address of the device that can be connected by the third control function of the control unit 35 of the living room base unit 3 or the control unit 45 of the mobile terminal 4 is controlled in advance by the control unit 35 of the living room base unit 3 or the mobile terminal 4. In addition to registering in the unit 45, the IP address of the transmission data is constantly monitored, and when an IP address that is not registered in advance is found, an abnormal connection is made to the display unit 33 of the living room base unit 3 or the display unit 43 of the portable terminal 4 Display a warning. Therefore, the resident who sees this can stabilize the signal transmission of the intercom system by avoiding abnormal connection.
