Automatic Number Plate Recording

Select System ANPR

System ANPR is a complete Automatic Number Plate Recognition System supplied in one box. It offers a cost effective solution for single and dual lane applications without compromising on quality. Key to the system is Select’s powerful Cleartone Recognition Engine used country-wide in mission critical security and law-enforcement applications.

Select System ANPR Cameras

The Select System ANPR range of cameras offer optimum performance for access control systems 24 hours a day in varying lighting and weather conditions. The housing provides a mounting for the ANPR camera at approximately the same height as front car plates, reducing the issues with line of sight problems i.e. tailgating or queuing traffic. The cameras are designed to work with the infra red retro reflective properties of number plates; the lighting and filtering technologies employed overcome issues associated with traditional CCTV cameras such as headlight glare.

The software aspect of the system runs on standard home computer hardware and can be linked to other applications or databases. It first uses a series of image manipulation techniques to detect, normalize and enhance the image of the number plate, and then optical character recognition (OCR) to extract the alphanumerics of the license plate. ANPR systems are generally deployed in one of two basic approaches: one allows for the entire process to be performed at the lane location in real-time, and the other transmits all the images from many lanes to a remote computer location and performs the OCR process there at some later point in time. When done at the lane site, the information captured of the plate alphanumeric, date-time, lane identification, and any other information that is required is completed in somewhere around 250 milliseconds.
