If you have never been in a Spy Camera Store you don’t know what you are missing
The first time I walked into a Spy Camera Store I felt like a kid on Christmas morning. They had all the standard store security kind of things, but then I noticed the stuff in the “Spy” part of the store. I could find microphones with remote monitoring abilities just like I saw on FBI movies. I saw some tiny cameras that were build into glasses and some so small the I could hide it is an empty cigarette pack and just leave in a room and be able to check out what goes on while I am in a complete different part of the house. This stuff is just so cool.
