ABSTRACT:
A covert surveillance camera assembly comprises a dummy sprinkler head for camouflaging a camera. The sprinkler head has a pair of parallel arms and a mirror is mounted in a predetermined position relative to the camera and between the arms of the sprinkler head. An associated mechanism for scanning an object area may include a rotating component for turning the mirror at a predetermined angular speed in a first direction about an optical axis of the optical device. A dovetail prism is provided for stabilizing an image transmitted from an outlet end of the surveillance assembly, the prism being rotated at one half the angular speed of the rotating mirror in a second direction about the optical device's axis opposite to the first direction. The camera includes (a) a housing, (b) a transducer disposed in the housing for converting incoming electromagnetic radiation into electrical signals, the transducer including a solid state image sensor, (c) an element for movably mounting the image sensor to the housing, and (d) a shifting mechanism operatively connected to the image sensor for reciprocating the image sensor along a substantially linear path in a direction essentially transverse to the incoming electromagnetic radiation.
