About License Plate Recognition (LPR)
License Plate Recognition (LPR) is a surveillance method that uses optical character recognition (OCR) on images to identify vehicles by their license plates. 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:

License Plate Recognition Applications
> > Access Control and Security. Used to replace or assist security guards, an automated License Plate Recognition system, in addition to a physical access control solution, can provide exclusive access comtrol.. Integrated 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. A LPR system is able to capture, store, and manage an image of the vehicle’s license plate, driver/passenger information, and a video recording of the activities.

> >Law Enforcement. Available in fixed or mobile installations, License Plate Recognition systems can perform real-time processing of license plate numbers and match the data against any predetermined list including stolen vehicles, amber/silver alerts, unpaid fines, outstanding warrants, etc. Utilizing LPR greatly increases productivity of officers, capturing 1000's of licence plates per shift.

> > 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 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 other factors influence the efficiency of an LPR system, such as:
- Vehicle Speed
- Volume of Vehicle low
- Ambient Illumiation
- Weather
- Vehicle Type & Height
- License Plate location on Vehicle
- License Plate Variety within Jurisdiction
- Camera-to-Plate Distance
- Spacing Between Vehicles
- Presence of Trailer Hitch, Decorative Frames, etc.
