ABSTRACT:
A pan and tilt mechanism for a surveillance camera that can pan through two full revolutions. A bell crank has one arm in the path of rotation of a pair of switches, and the bell crank can be shifted to extend the opposite arm. Each arm can be shifted by one switch, but will actuate the other switch to reverse the pan motor. The electrical cord for the mechanism and the camera is wound about the axis of rotation so the cord stays neat and undamaged through all rotation of the mechanism.
