Number Plate Recognition
API for developers
NPR API delivers production-grade number plate recognition with 99.8% accuracy. Read licence plates from images and video with latencies under 50ms.
Number plate recognition built for scale.
Our NPR engine is trained on millions of diverse plate samples to ensure robust recognition in low light, high angles, and challenging weather conditions.
Real-time Plate Recognition
Optimised inference engine delivering sub-50ms number plate reads. Perfect for high-speed tolling, parking, and access control applications.
Global Plate Support
