Actually it's even more sinister than that. Only one of the cameras was real, hence the unit needed to rotate, but you'd have a tough job spotting which camera was facing you. The camera turrets have two 'metal' strips on them, like a hot cross bun. These are actually mirrored panels and it's behind these that the camera would rest. From the outside, it looks like the camera is facing away from you if you're being observed.
Plus some of the units were completely dummy units, and would rotate at random.
I may be mistaken but I seem to recall hearing that, although they had many long lenses emanating from them, only one was truly connected to a camera.
