“Whether for good or bad, surveillance machines are going to get smarter. They’re already starting to recognise people’s faces in the street, and systems that spot abnormal behavior will not be far behind… Once connected to such intelligent systems, closed-circuit television (CCTV) will shift from being a mainly passive device for gathering evidence after a crime, to a tool for crime prevention…[The system works by detecting any behaviors that deviate from the ‘normal’ range of human behavior:] the computer recognises them as patterns. If anyone deviates from these patterns, the system sounds the alarm… it spots any abnormal behavior.” – New Scientist, December 11, 1999
