An image of the subject captured by the high-sensitivity camera 2 via the electric zoom lens 1 is sent to the camera unit / wireless modulation / demodulation unit 5 via the camera unit / image / control signal aggregation / distribution unit 4 and is modulated to a high frequency. . This high frequency is wirelessly transmitted between the camera unit / directional antenna 6 and the operation unit / directivity antenna 7, demodulated by the operation unit / wireless modulation / demodulation unit 8, and transmitted to the operation unit / image / control signal aggregation / distribution unit 9.
