Automated License Plate Readers

ALPRs are computer-controlled, high-speed camera systems—generally mounted on police cars or fixed objects such as light poles—that automatically capture an image of every license plate that comes into view. ALPRs can detect when a license plate enters the camera’s field, capture an image of the car and its surroundings (including the plate), and convert the image of the license plate into alphanumeric data—in effect “reading” the plate. ALPRs record data on each plate they scan, including not only the plate number but also the precise time, date and place it was encountered.
