DRIVE MECHANISM FOR SURVEILLANCE CAMERA PAN AND TILT

摘要

This invention discloses a camera pan and tilt mechanism wherein both the pan and the tilt motors are affixed to the stationary structure. Conventional systems are designed with the tilt motor affixed to a structure which is moved by the pan motor. Displacing the tilt motor from the structure which is moved by the pan motor allows the pan motor and the enclosing envelope to be smaller, and the design of the tilt motor and movable structure to be less complex. The overall result is a less massive, less costly, more reliable design, with faster dynamic performance.
