A camera control unit includes a control section for generating various control outputs, a power generator for generating power, and an identifying signal generator for generating an identifying signal. One end of a camera cable is connected to the camera control unit to transmit the control outputs, the power, and the identifying signal. A camera head is connected to the other end of the camera cable. The camera head includes a camera section for receiving the control outputs and sending a video output, an identifying signal detector for receiving the identifying signal and identifying the appropriate type of camera head, a power switch circuit for receiving the power and switching the power on the basis of an identification result of the identifying signal detector, and a power supply circuit for supplying the DC power from the power switch circuit to the camera section.
