Abstract: Disclosed is an apparatus for providing a pair of images to a fixed security camera, the apparatus comprising an angled mirror assembly comprising a left mirror and a right mirror joined at an edge therebetween and disposed at an angle between approximately 60.degree. and 120.degree., preferably 90.degree., to each other. The mirrors are mounted on the angled mirror assembly such that images transmitted through each of a pair of windows of a housing are reflected by the mirrors towards a camera assembly, and the mirrors are bevelled at a joining edge such that no image is generated from the area within and between the respective surfaces thereof. As a result, a left image incident upon the left mirror is reflected thereby towards the camera, and a right image incident upon the right mirror is reflected thereby towards the camera, and the resultant image captured by said camera is composed of a split image of the left image and the right image.

Abstract: A viewing device for installation on a wall or door includes a housing projecting from the front surface of the door and defining a plurality of surveillance ports disposed axially, and non-axially relative to the axis of the housing. By means of a knob extending outwardly from the rear door surface and defining a viewing port axially aligned with the axial surveillance port, the user is able to move a mirror between a first orientation intersecting the housing axis at an acute angle and a second orientation parallel to and spaced from the housing axis. Rotation of the knob relative to the housing causes rotation and pivoting of the mirror so that, when the mirror is in the first orientation, a line of sight is defined at different times from the viewing port through each of the non-axial surveillance ports via the mirror and, when the mirror is in the second orientation, a line of sight is defined from the viewing port directly through the axial surveillance port.

Abstract: The present invention provides a viewing device, said device being positioned within the outer and inner surfaces of an entry door, to ascertain the identity of prospective entrants from within the confines of a dewlling. The device includes on the outer surface of the door a turret wherein at least four ports retain a like series of wide angles lenses. One of said ports and its lens is situated axially along a line from the eyepiece for straight ahead viewing, while the three ports and complimentary lenses are situated radially at right angles in relation to said axial port so as to give complete views of the area below and to the right and left of the doorway. A mirror, being positioned by a cam means, transmits the light and hence the image from each port to the user within the dwelling. By repositioning the mirror, the user may ascertain the presence and identity of visitors within a complete one hundred eighty degree field before the door.

Abstract: A security viewing device which provides a viewer on one side of a door with a view of a caller whether he is standing directly outside the door or concealing himself to one side. The device includes a housing in which is mounted a stationary rotating periscope having an eye piece for the user at one end. The opposite end of the periscope is provided with two viewing ports facing in axial and radial directions. An inclined one way reflecting surface is mounted in the periscope adjacent the radial viewing port. The periscope with the two viewing ports end is enclosed in a clear plastic bubble with a portion of its top (northern) inner side darkened in opaque black. When the radial port is positioned upward or facing north, the user looks straight ahead through the one way reflecting surface and the axial viewing port at the caller.
