MINIATURE CAMERAS

摘要

A miniature camera (80) is fitted to a door (100), and comprises an elongate tubular housing (81) which extends between an outer face (101) and an inner face (102) of the door (100). An annular flange (82) is formed at one end of the housing (81), and bears against the outer face (101) of the door (100). An end cap (83) is secured to the inner door face (102) by means of a wood screw (104), and is connected to the housing (81) by means of a bolt (105). A cover (84) is provided with a transparent portion (85), and engages the housing (81) in a substantially waterproof and weatherproof manner. Mounted within the tubular housing (81) is a chassis member (90), which cooperates with a resilient member (87). Mounted on the chassis (90), substantially at right angles thereto, is a circuit board (92) which carries a CMOS/APS image sensor (93). A second circuit board (94) is also mounted on the chassis member (90), and extends in a direction generally parallel to the axis of extent of the chassis member (90). An adjusting screw (88) is mounted at the lower part of the tubular housing (81), and engages a projection (97) to adjust the angle of inclination of the chassis member (90), against a resilient bias of the resilient member (87). Cameras of other configurations are disclosed in the specification.
