Abstract: A camera, typically a security camera utilizing film in a cartridge, with means for determining when the film in the cartridge has been exhausted. A radiation emitter with the wavelength of the emitted radiation outside the sensitivity range of the film, a detector for the radiation of the emitter, and a reflecting surface, with the reflecting surface on one side of the film and the emitter and detector on the other side of the film so that presence of film blocks the radiation path from the emitter to the reflecting surface to the detector. A control circuit for controlling camera operation, with the radiation detector output serving to shut off power to the motor when the film supply is exhausted.

Abstract: A mount for a surveillance camera or the like for moving the camera between an operating position and a servicing position for changing film or lens or the like. The camera and mount have interengaging support means and a fastener for joining the support means together for supporting the camera. A shaft is positioned in a mounting bracket, with the shaft having threaded sections projecting upwardly and downwardly from the mounting bracket. The support means is fastened to the upper end of the shaft with a detent member carried on the shaft for engaging a detent member in the bracket, with the shaft detent member being adjustable with respect to the camera position. The shaft is clamped to the bracket by a nut or the like on the downwardly extending section. With the detents engaged, the camera is initially adjusted to the desired operating position and then the support means is clamped at the upper end of the shaft.

Abstract: A camera which includes film transport means for moving a strip of film past a lens and shutter assembly in a stepwise, frame by frame sequence, with the film being maintained stationary when the shutter is in the open position. A toothed driven gear is in operative engagement with a film driven reel. A mutilated drive gear having a toothed portion with an end gear tooth and a smooth peripheral portion is rotated in time relationship with the opening and closing of the shutter. The driven gear contains a space between adjacent gear teeth (as by removing one gear tooth) whereby the end tooth of the drive gear is received in said space to facilitate the smooth "meshing" of the drive gear with the driven gear.

Abstract: A temporary sighting device which can be used on a surveillance camera during installation and adjustment, and which includes front and rear spaced apart, parallel walls, each of which contains a window provided with cross-hairs, whereby lines of sight extending through an intersection of the cross-hairs in the rear window and about the outer perimeter of the front window define the field of view of the camera. In the preferred form, the sighting device is produced from paper card stock and is foldable to a collapsed, flat position for shipping purposes.
