LPR (Licence Plate Recognition)

LPR (Licence Plate Recognition), also called ANPR in some markets, uses cameras and image processing to detect a vehicle registration plate and convert it into searchable text. It can support access decisions, parking workflows, investigations and entry records when integrated with the relevant system. Accuracy varies with angle, distance, speed, lighting, weather, plate condition and regional formats, so a laboratory percentage is not a site guarantee. Design should cover camera placement, allow-list logic, manual exceptions, retention, audit trails and what happens when recognition fails. Plate data may be personal data and requires an appropriate purpose, access controls and retention policy. Testing should use representative vehicles and conditions and measure both missed reads and incorrect matches before automated barriers or alerts are trusted.
