| Automated Number Plate Recognition (ANPR) uses digital cameras and software similar to Optical Character Recognition (OCR) software to extract the registration data of vehicles. This can be done by pointing the camera at parked cars, but is most commonly done by deploying the camera adjacent to a road, and monitoring passing traffic. Variants have been used in most Australian States since the 1980s for heavy vehicle traffic. The technology is related to, but differs in some ways from, that used for 'speed cameras' and 'red light cameras'. |
