Guides, insights, and best practices for number plate recognition technology.
A technical and legal guide for developers building ANPR-based private parking enforcement systems, covering POFA 2012 Schedule 4 keeper liability, timestamp accuracy, grace period implementation and the NPR API confidence score as a compliance tool.
A practical developer guide to building API-driven ANPR access control for UK construction sites, covering architecture, whitelisting, DVSA vehicle checks, dwell time logging, and UK GDPR compliance. Includes a working Python code example using the NPR API recognition endpoint.
A technical guide for developers building barrierless ANPR enforcement systems for UK airport drop-off zones, covering the NPR API billing loop, dwell-time engine, edge cases, PCN pipelines, and GDPR data retention in a single end-to-end reference.
Learn how to build a multi-site ANPR platform using the NPR API, covering event normalisation, shared watchlists, webhook alert routing, journey correlation, vehicle data enrichment and UK GDPR compliance across distributed camera networks.
A practical developer guide to building ANPR-based residential access control, covering system architecture, allowlist data modelling, visitor token management, API integration with code samples, edge case handling and UK GDPR compliance obligations.
Hospital car parks are among the most technically demanding access-control environments a developer will encounter, combining 24/7 operation, multiple user classes, emergency vehicle overrides, and strict UK GDPR obligations. This guide covers architecture, API integration with the NPR API, user-class logic, and healthcare-specific data handling from design to deployment.
Polling an ANPR API adds avoidable latency and scales poorly under load. This guide shows you how to build a production-ready, webhook-driven plate-event pipeline using the NPR API, covering signature verification, idempotent deduplication, queue patterns and three real-world wiring examples.
Number plate cloning in the UK rose 53% between 2021 and 2025, yet basic ANPR cannot detect it. This guide shows developers how to combine plate recognition with DVSA vehicle data to catch make, model, and colour mismatches in real time.
A practical guide for developers building ANPR-powered private parking enforcement systems in the UK, covering the full pipeline from plate recognition and dwell-time calculation to PoFA 2012 compliance, DVLA integration, GDPR obligations, and evidence pack generation.
