Abstract: A surveillance system. The system includes an electrical device and a housing for at least partially enclosing the electrical device, the housing being selectable between self-mounting and box-mounting. In the preferred embodiment of the invention, the housing includes: (a) a mounting enclosure for mounting the electrical device; (b) at least one access port for providing access to the electrical device and; (c) a plenum adaptor for selectively self-mounting the surveillance system. Also, in the preferred embodiment of the invention, the surveillance system may include a protective cover attachable to the housing for protecting the electrical device.

Abstract: An optical device for reorienting an optical image from a first optical pathway to a second optical pathway and the method of manufacturing such an optical device. In a preferred embodiment, a housing is provided that defines at least two optical pathways. Both optical pathways align with a common aperture in the housing. Since both optical pathways are generally cylindrically shaped and the common aperture aligns with both optical pathways, the common aperture is elliptical in shape so as to correspond to the plane of intersection between the two cylindrical pathways. A generally rectangular mirror, that is larger than the elliptical aperture in the housing, is placed over the aperture on the exterior of the housing. As a result, the mirror covers the area of the elliptical aperture and redirects any light passing through the elliptical aperture from one of the optical pathways into the other optical pathway.
