ABSTRACT:
The present invention provides a method and system that improve the low-speed control stability of a video camera assembly, including a video camera, a tilt motor operable to tilt the video camera and a pan motor operable to pan the video camera. A first encoder is coupled to one of the tilt motor and pan motor. The first encoder outputs a plurality of signals having corresponding signal edges, based on a rotation speed of the one of the tilt motor and pan motor. A first controller is in electrical communication with the first encoder. The first controller determines a speed of the one of the tilt motor and pan motor at least in part by correlating a time period between detection of the first edge and detection of the second edge to the speed of the at least one tilt motor and pan motor.
