するための受話器である。Figure fn1 is a block diagram of an embodiment of the present invention, in which 1 is a TV camera that images a visitor, 2 is an intercom on the visitor's side, 10 is a monitor that displays the video signal of the TV camera 1 indoors 14, and 12 is an intercom that communicates with the visitor side intercom 2 in the room 14, and 4 is T
A mixing circuit that combines the video signal of the V camera 1 and the audio signal from the visitor's intercom 2; 5 is a modem on the visitor's side for communicating using a telephone line; 6 is a telephone line;
7 is a modem on the support side; 8 is a video/audio signal separation circuit that separates the video signal and audio signal synthesized by the mixing circuit; 10 is a video signal separated by the video/audio separation circuit 8; and 10 displays the video signal separated by the video/audio separation circuit 8. The monitor 11 is a receiver for communicating audio signals.
