PURPOSE: To operate a camera like a camera unified with a VTR and an electric universal head by radio by providing a camera-side transmitter-receiver and an operation-side transmitter-receiver.

CONSTITUTION: An operation-side transmitter-receiver 1 receives the signal from a camera-side transmitter-receiver 6 to display the picture photographed by a camera 8 unified with a VTR and the state of this camera on display devices 3 and 4. An operator operates a control input part 2 while seeing the display on display devices 3 and 4 to input a control signal. The camera-side transmitter-receiver 6 supplies the control signal from the operation-side transmitter-receiver 1 to the camera 8 and display devices 3 and 4 to not only drive the display devices 3 and 4 but also perform the required operation of the camera 8. Thus, the camera 8 and a universal head 11 are operated by radio.
