Surveillance is already the subject of more than 4000 peer reviewed scholarly article references on Citeseer, and is also the subject of an IEEE interntional conference.

Surveillance is derived from French "sur" (above) and "veiller" (to watch). Typically (though not necessarily) surveillance cameras look down from above, both physically (from high poles) as well as hierarchically (bosses watching employees, citizens watching police, cab drivers photographing passengers, and shopkeepers videotaping shoppers).
