DoorScope 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 super wide viewing angle, DoorScope leaves no dead zone for intruders to conceal themselves.
Without electrical connections, Doorscope is a simple do-it-yourself installation. The viewing image is free of distortion even at the edges. Say good-bye to your old peephole and stop stressing your eyes.
