License-Plate Recognition (LPR / ANPR) — One-Page Reference

What LPR is (LPR=ANPR; LPC is capture-only; identifies a vehicle and its keeper, not the driver), the four-step pipeline (find, clean, OCR, validate/match), accuracy as capture rate × read rate (≈98% × ≈95% ≈ 93%, never 100%) and the conditions that move it, the dedicated-camera requirements (fast shutter, IR, tight angle), how a plate event surfaces via ONVIF Profile M and where it runs, and the legal line (personal data but NOT biometric — GDPR + DPIA, UK ICO, California SB 34) — on one page.
