Max’s note: Here’s another great spy camera you can mount anywhere on the wall. Now, they need to make a U.S. version so it doesn’t stand out too much.
It may look like just a plain wall socket, but it is actually a Voice Activated Socket Spy Camera! Once the voice nearby reaches 65db, the socket will automatically turn to video mode and save the record for 5 minutes continuously. It supports AVI video format recording in a 640×480 pixels resolution. The socket has no built-in memory, but it can support up to 8GB TF card to store files.
