If you usually look through a peephole in your front door to see who is knocking, there’s another option and it may actually be more secure! With a bigger screen for visibility, a door viewer in your front door lets you easily see whomever is standing there or walking towards your door from 5-7 feet away. Because the door viewer displays what’s going on from a 2-inch size screen, even if you have poor eyesight, you can see.
The Family Handyman talks about the benefits of a door viewer and walks you through the process of installing one yourself in this article. Just like a peephole, you will need to cut a hole in your door, but only bigger, and then screw the door viewer in place.
