This CBS News hidden camera footage can probably be seen as variation on your basic nannycam, in this case directed towards those taking care of the elderly in a nursing home. An astute point made about the footage in question is that it may well be what you don't see that's as important as what you do, although since we don't really see the footage of nothing happening, we naturally have to take this man's word on faith.

The clip is also interesting for showing the mechanics of how the camera was set up, and for the indication that a state regulatory agency used the footage as evidence.
