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.
