FLOCK automatic number plate recognition
page 5 / 11
==== Sweden ====
The technique is tested by the Swedish Police Authority at nine different locations in Sweden.
==== Turkey ====
Several cities have tested—and some have put into service—the KGYS (Kent Guvenlik Yonetim Sistemi, City Security Administration System), i.e., capital Ankara, has debuted KGYS- which consists of a registration plate number recognition system on the main arteries and city exits. The system has been used with two cameras per lane, one for plate recognition, one for speed detection. Now the system has been widened to network all the registration number cameras together, and enforcing average speed over preset distances. Some arteries have 70 km/h (45 mph) limit, and some 50 km/h (30 mph), and photo evidence with date-time details are posted to registration address if speed violation is detected. As of 2012, the fine for exceeding the speed limit for more than 30% is about ₺315 (US$175).
==== Ukraine ====
The project of system integration «OLLI Technology» and the Ministry of Internal Affairs of Ukraine Department of State Traffic Inspection (STI) experiments on the introduction of a modern technical complex which is capable to locate stolen cars, drivers deprived of driving licenses and other problem cars in real time. The Ukrainian complex "Video control" working by a principle of video fixing of the car with recognition of license plates with check under data base.
==== United Kingdom ====
The Home Office states the purpose of automatic number-plate recognition in the United Kingdom is to help detect, deter and disrupt criminality including tackling organised crime groups and terrorists. Vehicle movements are recorded through a network of nearly 13,000 cameras that capture approximately 55 million ANPR 'read' records daily. These records are stored for up to two years in the National ANPR Data Centre, which can be accessed, analysed and used as evidence as part of investigations by UK law enforcement agencies.
In 2012, the UK Parliament enacted the Protection of Freedoms Act which includes several provisions related to controlling and restricting the collection, storage, retention, and use of information about individuals. Under this Act, the Home Office published a code of practice in 2013 for the use of surveillance cameras, including ANPR, by government and law enforcement agencies. The aim of the code is to help ensure their use is "characterised as surveillance by consent, and such consent on the part of the community must be informed consent and not assumed by a system operator. Surveillance by consent should be regarded as analogous to policing by consent." In addition, a set of standards was introduced in 2014 for data, infrastructure, and data access and management.
==== United States ====
In the United States, ANPR systems are more commonly referred to as ALPR (Automatic License Plate Reader/Recognition) technology, due to differences in language (i.e., "number plates" are referred to as "license plates" in American English)
Since 2019, private companies like Flock Safety have grown rapidly, promoting stationary ALPR cameras to private individuals as well as neighbourhood associations and law enforcement. By April 2022, 1500 cities across the United States had implemented Flock cameras, despite criticism from the ACLU and other civil rights organisations and concerns about whether the system actually reduces crime. In 2025, ALPR cameras are being used by ICE and ERO to search for "immigration" related activities, potentially aiding in deportation detainment. Currently, there is no need for a warrant nor restriction on how law enforcement can use ALPR data.
Mobile ANPR use is widespread among US law enforcement agencies at the city, county, state and federal level. According to a 2012 report by the Police Executive Research Forum, approximately 71% of all US police departments use some form of ANPR. Mobile ANPR is becoming a significant component of municipal predictive policing strategies and intelligence gathering, as well as for recovery of stolen vehicles, identification of wanted felons, and revenue collection from individuals who are delinquent on city or state taxes or fines, or monitoring for Amber Alerts. With the widespread implementation of this technology, many U.S. states now issue misdemeanor citations of up to $500 when a license plate is identified as expired or on the incorrect vehicle. Successfully recognized plates may be matched against databases including "wanted person", "protection order", missing person, gang member, known and suspected terrorist, supervised release, immigration violator, and National Sex Offender lists. In addition to the real-time processing of license plate numbers, ANPR systems in the US collect (and can indefinitely store) data from each license plate capture. Images, dates, times and GPS coordinates can be stockpiled and can help place a suspect at a scene, aid in witness identification, pattern recognition or the tracking of individuals.
