DoorViewer is an amazing high tech optical device. Mounted on any door, it allows you to have a clear view of the outside even if you stand 7 feet away from the door. With ultra wide viewing angle, DoorScope leaves no dead zone for intruders to conceal themselves. Without electrical connections, Doorscope is a simple, a do-it-yourself installation. The viewing image is free of distortion even at the edges.
