I've been reading the "Rain" series of contemporary fiction novels, and Rain (an assassin) has a detector he keeps in his pocket that "detects" some kind of wave length (side-band? or similar I think it was called) that video camera's produce. The detector also detects audio surveillance. The author never differentiates between wireless and hard-wired devices, this little thing picks up everything within about 10 meters or so if I recall correctly.

I'm just wondering if that is actually possible or if it is literary license. If it is possible, how?

That link says that current through a wire generates an electric field that can be intercepted. So not only can the field be detected, it can be read. This is called van eck phreaking.

Turn out the lights, hold a light right in front of your eye pointed away from you, look for lens glare.
