Yes - "back in the day", school buses equipped with video cameras would often just have a couple at each school, and they'd rotate the camera itself in and out of different identical enclosures in each bus. As kids, we never knew if our bus had the camera that day or not. There was a little dummy flashing LED on the box to make us think it was always on, so we'd be on our best behavior.
