Abstract: A dome camera assembly (10) of this invention includes a base housing (12) and a transparent dome (14). A pan motor (18), a tilt motor (20), and a video camera (22), are mounted to a movable platform (24) that is suspended by horizontal and vertical bearings (32, 36) to a platform support ring (26) attached to the base housing. The pan motor is direct-coupled to the platform support ring by a panning drive wheel (28) that pans the video camera through azimuthal angles. The tilt motor is attached to the movable platform and is directly coupled to the video camera for tilting the camera through elevation angles. The pan and tilt motors are mounted in a balanced configuration at opposite sides of the video camera with their drive shafts rotating about a common axis that extends through the center of gravity of the video camera.
