Re: eavesdropping detection

Yeah, you are correct that some cameras (especially the ones w/ CCD's) can see IR. However they are not tuned to the lower end of the IR band as normal IR goggles (at least the Russian tank driver pair that I have access to) and it is possible to use a laser designator style setup (toward the lower IR end) to defeat a normal video camera. As to turning the light off, unless you are dealing with a complete incompetant they will bounce it off a window or a spike reflector through a wall or roof. Another very good place to check for these style bugs is in fireplaces.
