ANPR stands for Automatic Number Plate Recognition. A technology that reads vehicle registration plates to create location data. Automatic Number Plate Recognition (ANPR) is a high-precision technology that reads automobile license plates without the need for human involvement it has many uses and benefits. This information is captured by scanners or cameras then cross-referenced for a range of traffic and law enforcement purposes.

History of ANPR

ANPR was invented in 1976 in the United Kingdom at what was then known as the Police Scientific Development Branch (PSDB) (now known as the Home Office Scientific Development Branch), and early systems were produced for use in 1979. However, ANPR (Automatic Number Plate Recognition) was originally used in the United Kingdom in the 1980s and has since become a standard in traffic control. The ANPR has a far longer history than most people realise. Many people believe that it was invented in this millennium based on its widespread use in recent years for a wide range of applications such as traffic studies, access control, and parking.
Early trial systems were installed in the UK on the A1 Road and at the Dartford Tunnel crossing on the M25 highway, but it wasn’t until 1981 that the first arrest was linked to ANPR detection of a stolen automobile.

How ANPR Works?

ANPR uses high-speed image capture to identify number plates as they pass by an infra-red camera. The license plates are then cross-referenced against a large database, checking for inconsistencies, information, or usage, depending on the application. By positioning cameras in fixed locations with high crime rates, the authorities are able to monitor the traffic and keep an eye out for suspect vehicles.
ANPR is therefore the underlying technology used to find a vehicle license/number plate and it, in turn, supplies this information to a next stage of computer processing through which the information can be interpreted, stored or matched to create an ANPR based application.

Where ANPR is used?

With so many vehicles on the road today, ANPR cameras are being used in so many different applications. This system is generally used by Law Enforcement Agencies (LEAs) including the police and Private companies and local authorities including retail parks, supermarkets, and privately- owned car parks.
ANPR is most notably used by the police force, with the main purpose to detect and deter criminality. The Driver and Vehicle Standards Agency (DVSA) also uses automatic number plate recognition (ANPR) technology at a local, regional and national level to help detect, deter and disrupt by targeting those operators who break the law.

Benefits of ANPR

There are many benefits of ANPR some of them are: Many organizations like Police, DVSA, and local authorities now use (ANPR) technology as their first of security system. ANPR provides added security and acts as a deterrent. People knowing that their number plate is being recorded and checked is usually enough to stop criminal behavior in advance. ANPR offers an extra measure of security for both public and private use. The best thing is that this system is automated and provides highly accurate monitoring and 24/7 operation without human intervention. They are more efficient than most individuals and therefore provide a more dependable service. Police make the best use of this technology, they browse the data collected through ANPR cameras and check for suspicious vehicles, or vehicles that were involved in a crime.
Because of the real-time imaging capabilities of ANPR, it is advantageous to a wide range of sectors. Historically, number plate recording would take time, and then sending out penalty notifications to people who broke traffic laws took even longer. Number plates, on the other hand, can be recognized and confirmed against a database almost instantly with ANPR. A penalty notice might be issued as soon as 48 hours after this. The quick response time of these cameras enables for a quick response to criminal conduct, ensuring that no unwelcome people break the law.
