Method and system for video surveillance system motor overcurrent protection
Abstract:
The present invention provides a video surveillance system, having a video camera; a motor operable to move the video camera; and a processor monitoring a value of a signal provided to the motor, the processor terminating the signal to the motor when the monitored signal value exceeds a predetermined value for a predetermined period of time. A network may be coupled to the processor for communication of the signal termination. The processor may reinitiate a signal transmission to the motor sufficient to maintain a position of the motor after a predetermined period of time, and the processor may monitor the signal transmission and adjust at least one of a zoom setting and focus setting of the video camera based at least in part on the monitored signal.
