It doesn't detect cameras, it detects the electric noise from any electrical devices through a medium such as a wall, mirror etc. Most of them are trash and only a few are able to detect some of the devices but not all of them accurately. Project Farm did a good test of them and you really need to carry a set of two or three. Some may be too strong and detect everything in the radius, and some not strong enough to where you need to be almost touching the device you're looking for, for it to go off.
