I'm fairly certain that there are peepholes in my two bathrooms in the walls shared with a neighbor's bathrooms.
One peephole is behind a mirror. I've heard about this problem in motel rooms but don't know exactly what's involved. Is it just a hole in the wall behind the mirror, and the silver on the back of the mirror is scratched off, or is there something else involved? Is there a way to locate the peephole without removing the mirror? I want to subtly find the hole and try to document if it's used.
The other hole is somewhere in a wall that's made of something the thickness of heavy cardboard on my side but finished to look like drywall. Any ideas on what this material is and how to find peepholes in this material? I tried turning off the light, hoping that the light was on on the other side so that I could see the hole, but I think that they block the hole when not in use and turn off their light and close their door when using the peephole.
My thinking is to collect some evidence, then get the police to inspect the neighbor's place. Any comments that don't involve violence?
Thanks
