Abstract
A closed circuit television apparatus comprises a plurality of transmitters each including a remote-controlled television camera for generating video signals to a central supervisory station and a circuit for generating first code signals corresponding to a camera code allotted to the television camera, a receiver which receives the video signals and displays images corresponding to the received video signals. A controlling device is provided for controlling the television camera, receiving the first code signals, generating control signals to control the television camera and second code signals corresponding to the received first code signals, and transmitting the control signals and the second code signals to the television camera. A switching device is connected to the transmitters for selecting a transmitter to be connected to both, the receiver and the controlling device. Each transmitter includes a driving circuit for receiving the control signals and the second code signals generated in the controlling device, regenerating the control signals and the second code signals and operating the television camera based on the regenerated control signals when a code corresponding to the regenerated second code signals coincides with a code corresponding to the first code signals.
