The Digital Peephole Viewer is the peephole of the future. Front doors have been waiting for this for awhile now.
The Digital Peephole Viewer fits right over your existing peephole and runs on two AA batteries. The fish-eyed image you'd normally see is replaced with a crystal clear one on a digital display. Check the links if you want to grab one of these home security enhancers today. I know I sure do.
