When you are using a "self check-out" in a supermarket or retail store, how many people are just watching your every move on surveillance camera?

However many are in the security office at the moment.

Probably just two at most: Anyone who happens to be looking at the security monitor (and they likely can't see much--those things don't have the best resolution) and the station attendant, whose attention is divided between probably four to eight stations. The point of the self-checkout, after all, is to reduce the workforce. It would make little sense to have a dozen people watching. There have been developments in loss-prevention computer surveillance, though. Cameras at the check-out station and throughout the store can identify suspicious behavior and alert personnel to watch more closely. There was an interesting article in a recent issue of Popular Mechanics on the subject.
