About License Plate Recognition (LPR)
License Plate Recognition (LPR) is a surveillance method that uses optical character recognition (OCR) on images to identify vehicles' license plates characters and numbers. Since every vehicle carries a unique license plate, no external cards, barcodes, tags or transmitters are needed in order for a vehicle to be recognized. LPR is also referred to as:
LPR can be configured in many languages
License Plate Recognition Applications
Access Control and Security. Used to replace or assist security guards, an automated License Plate Recognition (LPR) system, in addition to a physical access control solution, can provide exclusive access to a facility. Integrated LPR software allows facility managers the ability to pre-define entry and exit regulations and level of access — such as limiting admission to certain hours or days of the week.
Law Enforcement. Available in fixed or mobile installations, License Plate Recognition systems can perform real-time processing of license plate numbers/characters and match the data against any predetermined list* including stolen vehicles, amber/silver alerts, unpaid fines, outstanding warrants, etc.
Parking Facilities. A vehicle's license plate information is transferred to an existing parking management access control system to automatically permit entry/exit to authorized members. Captured information may be used to calculate overall parking time, provide proof of parking in case of a lost ticket, or enable officials to issue fines or parking tickets.
License Plate Recognition Efficiency
Recent software innovations and improvements have made LPR systems much more reliable. In a majority of cases, a LPR system strongly enhances existing security systems. LPR uses optical character recognition (OCR) and must be adapted to the country in which the cameras are installed due to different license plate designs and languages. Many factors influence the efficiency of an LPR system, such as:
