ABSTRACT:
A sealed and pressurized housing for a TV camera. The camera is mounted on a cradle which includes the sealing mechanism for both ends of the housing. Both ends are sealed with conventional "O" ring seals and end plates which are secured to the cradle. Since pressure is always equalized against both end plates and they are mechanically connected, when the housing is opened, no parts can be dangerously propelled upon release of the pressure. The cradle is also mounted so that, despite the internal pressure, it can be rotated relative to the fixed outer casing in order to adjust the angle of the camera to the horizontal.
