DH992 Mechanical Doorbell Peep Hole Viewer

The DH992 is a mechanical door chime that features a viewer, a.k.a a peephole.  In this day and age, it is very hard to find a wired door chime that is purely mechanical – meaning it does not require batteries or electricity.  The brass plate with black button is what the visitor sees and it is connected to the chime box on the inside of the door.  This kit also features a peephole viewer as well so you can see who is at the door.
