US Patent 7534057 Surveillance camera gimbal mechanism

A surveillance camera gimbal mechanism. The mechanism utilizes a rotationally adjustable disk and support arrangement to afford smoothly adjustable, fastener-free, and stable diagonal adjustment that also provides axial compliance. The diagonal adjustment mechanism is integrated with a pan and tilt gimbal mechanism to allow smooth and stable single-point manual fixation of pan and tilt positions without creating depressions in the mating parts which make readjustment difficult.
