How does spy camera watching work?

A wireless spy camera is a very small mini camera that you can use without connecting wires to a recorder. The camera will come with a receiver which connects to your TV for viewing. You can also connect the receiver to your VCR or to a DVR for recording.

Usually powered by a 9V battery which yields approximately 4 hours. The site below has their own rechargeable battery packs that will power a mini cam for up to 12 hours.
