Frequently Asked Questions
How Do Reverse Peephole Viewers Work?
A peephole viewer is basically a telescope. It is comprised of lenses that are set in a way that you can see what’s going on outside in with a wider field of view, meanwhile, the lenses are also set to narrow the field of view when looked from outside. With a reverse peephole viewer, you basically reverse the convex lenses that a door peephole features, so one can say that the reverse peephole viewer is another telescopic device that can cancel the effect of the peephole, and enable you to look inside a room from the outside. (2)
Most reverse peephole viewers feature a movable lens, so you can adjust the lenses to clear the picture of the room. Most peephole reversers are compatible with any standard peepholes by easy adjustment on the lenses by using the turning ring on the peephole reverser, to adjust your focal point for a clearer view.
Who Uses Reverse Peephole Viewers?
At first, reverse peephole viewers were designed to aid law-enforcement for close encounter situations, in order to provide officers with information about what is going on inside the dwelling. This gives them additional advantage and security in certain actions where the officers can find out what’s going on inside, before entering the room.
Reverse peephole viewers are also used by private investigators, bellboys, hotel managers, or any individual that needs to know what hides behind a door with a peephole.
Can they be Defeated?
A peephole reverser can be easily defeated. All you need to do is cover your door peephole from the inside, which you can accomplish by buying a peephole with a swing-out cover on the inside lens. When the cover is closed, you cannot use a reverse peephole viewer from the outside.
There is also another way of defeating a reverse peephole viewer. You can buy a “projection peephole” which projects the outside image on a small digital screen on the door, so you will not be able to reverse this peephole at any time.
Are they Legal?
Contrary to popular belief, peepholes are not illegal. You can easily order a peephole online, and they are highly affordable as well. While some may argue that these gadgets are supposed to be illegal, you may find these gadgets incredibly useful, especially when you need to find out what’s on the other side of that closed door.
