First, there is so much wireless spy camera, can you tell me the other requirement you need?
Second, if you bought a spy camera, there must be user manual ,so it's no problem to ask how to use it.
Third, i'm not sure which model of wireless spy camera you hopes, but i just find a online store: http://www.wiseupshop.com/. Maybe it's helpful for you.
These devices work on a simple principle. The camera contains a wireless radio (RF) transmitter. This transmitter broadcasts the camera's video, which can be picked up by a receiver, which will be connected to a monitor or recording device. Some receivers have built-in storage, while others must be connected to a DVR.
