Abstract: The present invention is relative to a controlling method for a wireless camera in a wireless camera system. This wireless camera system (300) includes a wireless camera (210) capable of transmitting image signals over a wireless route, a cabled camera (310) for transmitting image signals over a cable, and a receiving apparatus (400) for receiving the image signals transmitted from each camera and for controlling the camera. The wireless camera superposes a response signal to a control signal from the receiving apparatus on the image signals to send the resulting signals to the receiving apparatus over a wireless route.
