Automatic number plate recognition (ANPR) is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. ANPR is used by police forces around the world for law enforcement purposes, including to check if a vehicle is registered or licensed. It is also used for electronic toll collection on pay-per-use roads and as a method of cataloguing the movements of traffic, for example by highways agencies.

Hikvision aims at providing a reliable, accurate and cost-effective automatic number plate recognition (ANPR) solution with its range of ANPR cameras. The ANPR camera range supports powerful noise reduction and head light compensation technology to produce an excellent image for number plate recognition at night and are supported on the complete range of I-Series NVR

Outputs are available on both the camera and the NVR to cause certain actions to happen upon finding on “blacklist” or “whitelist”. eg. opening a gate / alerting security
