The UK has an extensive automatic number plate recognition (ANPR) CCTV network. Police and security services use it to track UK vehicle movements in real time. The resulting data are stored for 2 years in the National ANPR Data Centre to be analyzed for intelligence and to be used as evidence.〔 Following the formation of the Conservative – Liberal Democrat Coalition after the 2010 General Election, it was announced in July 2010 that the system is to be placed under statutory regulation. This is likely to establish a right in law to collect the data, and place controls on its use, storage and access by third parties.〔('Big brother' traffic cameras must be regulated, orders home secretary ), The Guardian, published 2010-07-04. Retrieved 14 August 2010〕 The Protection of Freedoms Act 2012 was enacted in order to provide for tighter regulation of ANPR. ==The ANPR CCTV network== Since March 2006, most motorways, main roads, town centres, London's congestion charge zone, ports and petrol station forecourts have been covered by CCTV camera networks using automatic number plate recognition. Existing traffic cameras in towns and cities are being converted to read number plates automatically as part of the new national surveillance network. "What we're trying to do as far as we can is to stitch together the existing camera network rather than install a huge number of new cameras," - Mr Whiteley chairman of the ANPR steering committee said. Some cameras may be disguised for covert operations but the majority will be ordinary CCTV traffic cameras converted to read number plates.〔 Every police force will also have a fleet of specially fitted police vans with ANPR cameras.〔 All data generated is fed to The National ANPR Data Centre. One camera can cover many motorway lanes. Just two ANPR devices, for instance, cover north and south movements through the 27 lanes of the Dartford crossing toll area on the Thames. Whiteley said the intention eventually was to move from the "low thousands" of cameras to the "high thousands".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Police-enforced ANPR in the UK」の詳細全文を読む スポンサード リンク
