What is automatic number plate recognition (ANPR)?
Automatic number-plate recognition ( ANPR; see also other names below) is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task.
How do the police use ANPR cameras?
The police use ANPR to “detect, deter and disrupt criminality”. This could mean anything from detecting uninsured and untaxed vehicles to locating stolen vehicles, or even solving cases of major and organised crime. Around 11,000 ANPR cameras submit around 50 million ANPR records daily.
What are the disadvantages of ANPR technology?
ANPR technology must take into account plate variations from place to place. Privacy issues have caused concerns about ANPR, such as government tracking citizens’ movements, misidentification, high error rates, and increased government spending. Critics have described it as a form of mass surveillance.
