The Brinno Digital PeepHole Viewer uses an LCD panel to display who is at your door without alerting them to your presence. The PeepHole Viewer turns a hard to see peep hole image into a big bright image. Simply push the button to see a large image of the person outside your door.
The image is easy to see for people of any height and is similar to that on the display of a digital camera. The viewer compensates for low-light images and eliminates fish eye distortion.
