ABSTRACT:
A viewing device for mounting in a wall or door frame to provide a view of the exterior of the building to an occupant of the building comprises a tubular housing and a pair of reflectors mounted by arms at one axial end of the housing so that they extend axially outward from the housing. The device further includes a transparent view housing which encloses the reflectors and prevents rearrangement of the reflectors while at the same time permitting a clear view of the area directly in front of the housing. The interior end of the tubular housing is enclosed by an eyepiece which can preferably be a magnifying type lens to increase the size of the images reflected from the reflectors and perceived through the transparent view housing.
