Abstract
A method and a system for video camera assembly are provided. The video camera assembly includes at least one of a pan mechanism rotatable about a pan axis and a tilt mechanism rotatable about a tilt axis. The pan mechanism includes a pan motor and a pan position encoder. The tilt mechanism includes a tilt motor and a tilt position encoder. A controller is communicatively coupled to at least one of the pan mechanism and the tilt mechanism and is configured to apply a filter to a power drive signal of at least one of the pan motor and the tilt motor based on a determined corresponding rotational speed of the at least one of the pan motor and the tilt motor with the effect of reducing steady state vibrations which degrade the visual and audible qualities of said video camera assembly.
