The reverse peephole viewer is designed for police to look through a peephole from the outside and let them see perfectly through into an apartment or house. While you may start to think that this is a pretty cool little gadget why don’t you think about the real people that are probably buying these things. All of your neighborhood creeps probably carry these things around in their pockets.
This gets me thinking though, if someone holds this up to the outside of a door then they can see perfectly through. What would the person inside the apartment/house see if they happened to look through the peephole? If there was enough light entering the peephole would they see a gigantic eye? Hmmm…too much thinking!
