2. Description of the Related Art In recent years, with an increasing interest in security, a TV intercom that can respond to a call by voice while confirming the image of the visitor from a conventional intercom device that can communicate with the visitor only by voice. The mainstay of dissemination to devices (entrance videophones) is changing.

[0003] An entrance videophone is an outdoor subunit that is usually installed at the entrance or a gate, and is composed of a camera unit, a communication unit, a control unit, and a power supply unit. The master unit is connected with a wiring cable. Then, when the visitor presses the ringing bell provided in the entrance slave, a call signal is transmitted to the indoor master, and the indoor master supplies power to the entrance slave and turns on the camera unit and the audio unit. At the same time, the monitor television unit provided in the indoor master unit is turned on.
