Automated License Plate Reader


Automated License Plate Reader (ALPR, Automatic number-plate recognition, ANPR or LPR) are high-speed, computer-controlled image systems that are typically mounted on street poles, street lights, highway overpasses, mobile trailers, or attached to police squad cars.

Automated License Plate Readers capture all License Plate or other number-based data that come into view using Optical Character Recognition, along with the location, date, and time. The data, which includes photographs of the vehicle and sometimes its driver and passengers, is then uploaded to a Data Store and typically used for Identity Correlation

Automated License Plate Reader usage#

  • Law Enforcement Agency - Mobile ANPR use is widespread among Law Enforcement agencies at the city, county, US State and United States federal government level. According to a 2012 report by the Police Executive Research Forum, approximately 71% of all US police departments use some form of ANPR. Mobile ANPR is becoming a significant component of municipal predictive policing strategies and intelligence gathering, as well as for recovery of stolen vehicles, identification of wanted felons, and revenue collection from individuals who are delinquent on city or state taxes or fines, or monitoring for "Amber Alerts". With the widespread implementation of this technology, many US States now issue misdemeanor citations when a license plate is identified as expired or on the incorrect vehicle. Successfully recognized plates may be matched against databases including "wanted person", "protection order", missing person, gang member, known and suspected terrorist, supervised release, immigration violator, and National Sex Offender lists.[42] In addition to the real-time processing of license plate numbers, ANPR systems in the United States collect (and can indefinitely store) data from each license plate capture. Images, dates, times and GPS coordinates can be stockpiled and can help place a suspect at a scene, aid in witness identification, pattern recognition or the tracking of individuals.
