Door Viewer is an extraordinary high tech optical device that virtually replaces the conventional peep hole. When mounting this unit on any door, you will have a clear view of the outside even if standing six feet away from your door. Featuring an ultra-wide viewing angle, the Door viewer leaves absolutely zero dead zone for unwanted guests or intruders to conceal themselves.
Door Viewer requires no connection to a power source or battery and is a simple installation you can do yourself. The viewing image clearly lets you see your visitors with no visual distortion even at the edges. Say goodbye to your old peephole and stop putting yourself in harm of potential intruders.
