License Plate Recognition (LPR)
A camera and software system designed to capture and interpret vehicle license plates at controlled approach points.
What is License Plate Recognition (LPR)?
License plate recognition uses purpose-built cameras and analytics to capture readable plate images and convert them into searchable text. LPR is used at parking entrances, gated communities, loading areas, and vehicle access points. It is different from a general overview camera: success depends on controlling the view, distance, angle, vehicle speed, lighting, shutter settings, and image size at the plate. A reliable design starts with the capture point. The camera is aimed at a narrow lane where vehicles approach predictably, often with infrared illumination for night operation. The network, recording platform, retention period, database permissions, and privacy policy must also be coordinated. LPR results are never perfect, so operators should retain the associated vehicle image and verify critical matches. Before pricing, confirm the number of lanes, mounting locations, conduit and power responsibilities, software licensing, integrations, and required retention.
