Pressurized housing for surveillance camera
First Claim
1. A housing for a surveillance camera, said housing comprising an assembly plate defining a central opening therein, a hemispherical lower dome having an outwardly turned flange, said lower dome being received within said central opening of said assembly plate with said outwardly turned flange received by said assembly plate, an upper enclosure received on said assembly plate, said upper enclosure including flanges fixed to said assembly plate radially outwardly of said lower dome, first sealing means for sealing said flange of said lower dome with respect to said assembly plate, second sealing means for sealing said flange of said upper enclosure with respect to said assembly plate, and valve means for introducing gas under pressure into an interior defined by said lower dome and said upper enclosure.

Abstract
A housing for a surveillance camera is generally dome shaped, the camera being movable therein, and the interior of the housing is under pressure to exclude contaminants. The housing is made up of an assembly plate having a central opening to receive a lower dome therethrough, with an upper enclosure placed on top of the assembly plate. The lower dome and upper enclosure are sealed to the assembly plate to retain gas under pressure within the interior. An accessory bracket is carried by the assembly plate within the upper enclosure, and a surveillance camera is mounted from the accessory bracket. An upper dome may be placed over the upper enclosure as a sun shield. In installing the housing, a mounting bracket is first installed, then the assembly plate is carried by the mounting bracket. The lower dome is put into place, followed by the accessory bracket, the upper enclosure, and finally the upper dome. Subsequently, the interior can be pressurized by the introducing gas through the valve.
