When I was at OKW a while back, security brought a dog and something that appeared to be similar to a vacuum around. It looked as if they sucked out a little air from the room, stood there for a little, and then went to the next door. The "vacuum" wasn't really audible, though. Certainly not the most common room check system, and I haven't seen them do it since, but I found it interesting.
