A surveillance camera system comprises a spherical housing that has a partially transparent lower, hemispherically shaped gold coated dome with a geometric center. A camera mount is mounted in the housing for panning movements about a vertical pan axis and tilting movement about a horizontal tilt axis. A video camera is mounted to the camera mount and electric motors are mounted for panning and tilting the mount and camera. A computer and control circuit is mounted to the camera mount and coupled to actuate the electric motors to orient the camera and to actuate the camera zoom and focus as well as to enhance the camera's video image with descriptive word captions. The computer is programmed for automatic or manual operation of the system. A rotary electric connector is mounted to the housing and connects the on board computer with a joystick and control unit for issuing instructions to the computer and connects the camera to an ancillary video display. |
