The 'Roving Eye' -- The new vehicle equipped with a Television Camera, V.H.F. sound and vision transmitters, power unit and gyro-compass controlled aerial. This unit, which is at present in the experimental stage, is intended for use in bringing topical outside events to viewers. Under favourable conditions it can work within a radius of some two miles of a fixed receiving point and the camera can operate when the vehicle is in motion or stationary. If the vehicle is moving the gyro-compass control ensures that the bearing of the transmitting aerial on the van is maintained correct with respect to the fixed base irrespective of vehicle movements.
