Abstract

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.

Claims

1. A surveillance camera system comprising:

a housing;

a camera mount including a camera receiving platform mounted for panning movement about a pan axis and tilting movement about a tilt axis;

means for releasably mounting said camera mount within said housing with said means comprising a first mounting plate positioned within and secured to said housing and a second mounting plate secured to said camera mount;

said first mounting plate including a set of depending pins having heads and said second mounting plate including a set of corresponding slots configured and positioned to receive and lockingly engage with said pins upon juxtaposition and rotation of said first mounting plate relative to said second mounting plate;

electric motor means on said camera mount for panning said camera receiving platform about said pan axis and tilting said camera receiving platform about said tilt axis;

orientation control means mounted within said housing for selectively actuating said electric motor means to control panning and tilting movement of said camera receiving platform;

remote control means for controlling said orientation control means from a location remote from said surveillance camera system; and

rotary electric coupling means mounted within said housing with said coupling means including electric connector means for operatively connecting said orientation control means with said remote control means and for electrically connecting a camera secured to said camera receiving platform with an ancillary video display.

2. The surveillance camera system of claim 1 wherein each of said slots is generally arcuate having a diameter greater that a corresponding pin and less than the pin head with one end portion of each slot sized to pass a corresponding pin head therethrough.

3. The surveillance camera system of claim 2 further comprising at least one pin head receiving depression formed in said second plate at the other end portion of one of said slots with said depression being configured and positioned to receive a corresponding pin head in secure holding relationship upon juxtaposition and rotation of said second mounting plate relative to said first mounting plate to lock said first and second mounting plates in mutually fixed rotary orientations.

4. The surveillance camera system of claim 3 further comprising a washer mounted about each of said pins with each washer being yieldably spring biased toward engagement with said pin head to urge said second plate away from said first plate upon juxtaposition and rotation of said second plate relative to said first plate whereby the pin heads are urged into locking position nestled within said pin head receiving depressions.

5. The surveillance camera system of claim 1 wherein said orientation control means comprises a computer and control circuit mounted on said camera mount with said control circuit being configured to actuate said electric motor means selectively in response to instructions issued from said computer to control the orientation of a camera secured to said camera receiving platform.

6. The surveillance camera system of claim 5 wherein said remote control means includes a keypad and wherein said computer is programmed to issue orientation controlling instructions in response to directives entered by an operator through said keypad.

7. The surveillance camera system of claim 6 wherein said remote control means further includes a joystick and wherein said computer and control circuit has a manual operation mode wherein a camera secured to said camera receiving platform can be oriented in response to corresponding manipulations of said joystick by an operator.
