The word surveillance is the French word for “watching over”; “sur” means “from above” and “veiller” means “to watch”. The inverse (reciprocal) of surveillance is sousveillance (“to watch from below”). The word surveillance may be applied to observation from a distance by means of electronic equipment (such as CCTV cameras), or interception of electronically transmitted information (such as Internet traffic or phone calls). It may also refer to simple, relatively no- or low-technology methods such as human intelligence agents and postal interception.
Surveillance cameras are video cameras used for the purpose of observing an area. They are often connected to a recording device or IP network and may be watched by a security guard or law enforcement officer.
