This invention relates to a communication system and more particularly, but not exclusively, to a visual and audio communication system. The communication system consists of a video camera which is connected to a portable wireless transceiver. An image from the video camera is transmitted from the wireless transceiver to a signal repeater from where the video signal is transmitted over a telephony communication system to a second transceiver. The second transceiver is arranged to display the video signal on a display means. A first control device is connected to the second transceiver for transmitting a control signal over the telephony communication system to the signal repeater and from the signal repeater to the portable wireless transceiver and to a second control device connected to the portable transceiver for controlling the video camera or an operator of the video camera. The classification is H04N, H04M, H04L.
