How automatic license plate recognition technology works
Original: How does ALPR technology work?
Automatic license plate recognition (ALPR) uses cameras paired with optical character recognition software to read vehicle license plates and log their location and time. The technology is widely used by law enforcement to track vehicles, locate stolen cars and aid investigations, but its growing deployment has drawn scrutiny from civil liberties groups concerned about mass surveillance and data retention of drivers' movements.
Why now: Growing use of ALPR cameras by police and questions about privacy have put the technology under public attention.
