Abstract
A camera housing is fixed against rotation in a cavity in a backbox which is mounted in a ceiling. The housing carries a camera module which is rotatable about a vertical axis with respect to the housing, the module in turn carrying a camera which is pivotable about a horizontal axis with respect to the module. The housing is held in place in the cavity by a locking ring which is received around the camera module and engages a backbox ring fixed to the backbox. The locking ring has an outward facing cylindrical surface which is concentrically received in an inward facing cylindrical surface of the backbox ring. The surface on the locking ring has cam followers which ride up a cam ridge on the surface of the backbox ring as the locking ring is rotated, in order to position the camera housing in the backbox. A spring loaded detent mechanism holds the locking ring in the locked position until it is counter-rotated to overcome the spring force.
