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.
