ABSTRACT:
The system includes improvements to a remote tracking system for motion picture as well as still picture cameras. The system provides for improved motor control for PAN and TILT functions including motor turn-off in the event of stall; the use of optical means to provide position feedback through the use of a light-blocking disk graduated on a "gray scale" which eliminates mechanical contacts; mechanical levers that are motor driven for operation of ON/OFF and ZOOM functions of a motion picture camera or shutter control for a still camera via either the base or remote unit command circuitry. The remote unit is formed as a hand-held wand and also provides audio circuitry. A space diversity RF receiver is used to improve the communication link between the remote unit and the base unit.
