ABSTRACT:
The system includes a base unit sensitive to infrared (IR) signals transmitted by a mobile remote unit to an IR receiver which is placed behind a rotating set of signal blocking blinders whose position at any time defines a view angle with a position known with precision resulting in the IR signal reception scanning across an area. The base unit detects when the peak strength of the signal occurs and utilizes this data to determine the exact effective angle between the axis of the IR signal and the base unit to create an error signal used by the base unit to position the camera mounted thereon. Receivers for TILT and two PAN positions, PAN 1 and PAN 2, are used to include range calculations for ZOOM functions. Command circuitry to override the automatic tracking function is provided in the base unit.
