I’m thinking of Spy cameras. When I was being bullied I did some research into Spy recorders After seeing the Karen Klein video, I did some research into spy cameras. Below is a list of links that are examples of Audio & Video surveillance, and 2 web pages I found about the laws of surveillance. It is unclear about employee taping employer laws. Please do more research and consult with a lawyer.
