Public areas, underground stations, shops and banks are equipped with inconspicuous cameras
recording the movements and actions of passers-by and customers and feeing them into closed
circuits (camera - monitoring centre - analytical software). CCTV is most widely used in the UK where
approximately 200,000 cameras are in use, a number, which is growing at a rate of 500 per week. In
the centre of London it is already possible to track an individual's complete itinerary between any two
points.
As a result of technological development, the performance of these systems has greatly increased.
Ever since 1994, CCTV systems have been able to recognise faces and to compare them to existing
samples stored in databases. Recently, systems have been developed that are capable of recognising
movement and behaviour patterns. Suspicious movements set off an alarm, which allows security
personnel to intervene before the suspected criminal act can be committed. CCTV is also widely used
in industrial settings, where it is employed for a permanent, efficient and inconspicuous control of
workers' performance.
Another field of application of CCTV is traffic control. CCTV systems capable of reading car
registration numbers allow a large-scale supervision of urban traffic flow. Police not only use CCTV for
a permanent and automatic search for criminals in public areas, they also promote technological
improvements. Prototypes of cameras and microphones integrated into police helmets, directly
transmitting data to the nearest police station, have been tested successfully.
