Brinno has a great device for the digital home. This electronic peep hole viewer allows you to see who is at your door without having to squish your nose to use the little hole. This easy DIY install device has a digital camera on one end and a LCD display on the other end. With a press of a button, the viewer powers on and shows who's a knock'n. It operates on double A batteries and each time you press the button it will be on for about 10 seconds. This device is great for kids who can't reach the peep hole and we believe it should be installed in every hotel room.
