Closed-circuit television (CCTV), as a collection of surveillance cameras doing video surveillance, is the use of television cameras for surveillance. It differs from broadcast television in that all components are directly linked via cables or other direct means. CCTV is often used in areas where there is an increased need for security, such as banks, casinos, and airports. They may also have military uses. The use of CCTVs in public places has increased, causing debate over security versus privacy.
CCTV was initially developed as a means of increasing security in banks. Today it has developed to the point where it is simple and becoming inexpensive enough to be used in home security systems, and for surveillance, although wide-spread use is still some 15 years away.
CCTV is also used in anti-terrorism campaigns, as evidenced by France's use in response to the FCL and FLNC. Other uses include Louisianne's use in train stations and other vital services and London and many other metropolis's to aide in traffic control.
CCTV has come under strong criticism by populations around the world as they feel it invades upon personal civil liberties. To date, only Andorra has banned its use within the country except for use internally in the Prince's castle for security purposes.
