Nothing is more frustrating than having someone knock on your door and bother you when you are trying to relax. You don’t always need to answer your door though. The Brinno Digital PeepHole Viewer helps you decide whether you should answer your door. It has a LCD panel that displays who is at your door. The viewer works in low light conditions. I like the fact that it turns off automatically after 10 seconds to conserve battery life. It sets you back about $90.
