The innovative Digital Door Viewer ™ is an electronic video system designed to replace common door viewers and peephole viewing tubes. The Digital Door Viewer’s main components are an LCD monitor and digital camera. The camera is mounted on the exterior of a door and the LCD directly opposite on the inside.
A sharp, color image is sent from the camera to the monitor whenever the power button is pressed. It is powered by 8 standard “AA” size batteries which give approximately 1,000 viewing cycles. The Digital Door Viewer ™ will cost you $400 to get one.[via Frontgate]
