ANPR Camera Systems: How License Plate Recognition Is Revolutionizing Traffic Management
Automatic Number Plate Recognition (ANPR) technology has evolved from a niche law enforcement tool into a mainstream traffic management solution deployed across highways, toll plazas, parking facilities, and smart city infrastructure worldwide. For OEM camera manufacturers and system integrators, ANPR represents one of the fastest-growing segments in the surveillance industry. How ANPR Works: The Technical Foundation ANPR systems use a combination of high-resolution imaging, infrared illumination, and optical character recognition (OCR) to capture and process license plates in real-time. Modern ANPR cameras process everything on-device using Edge AI, eliminating the need for server-side processing and reducing latency to under 100 milliseconds. The key technical requirements for effective ANPR include: Resolution: Minimum 2MP, with 3MP-5MP preferred for multi-lane coverage Shutter Speed: Global shutter or high-speed electronic shutter (1/10000s) to capture plates on vehicles moving ...
