ABSTRACT:
A novel and useful surveillance camera housing assembly is provided. The assembly is easily mounted as a sturdy arrangement as a rectangular section of a suspended ceiling. A pair of side supports of the assembly extend over the cross forming inverted T-shaped ceiling support members which define the rectangular section and rest on the outer edges of each of the inverted T-shaped ceiling supporting members. A bridge spans the side supports from which a surveillance camera mounting depends. A frame with radiating legs is attached to the camera mounting. An inner dome is attached to the frame in a quick detachable relationship. An outer dome with a rectangular base approximating the size of the rectangular section is provided along one edge with horizontally projecting ears for supporting the outer dome between two parallel disposed inverted T-shaped ceiling support members when the outerdome is pivotted downwardly about the horizontal axis of the ear bearing edges of the outer dome.
