Mobile ANPR

Automatic Number Plate Recognition (ANPR) is a critical part of many of Enforcement Deputy’s traffic law enforcement features, from parking to speeding, from our Bus Lane Enforcer to our Road Safety Alert System.

ANPR works quietly in the background, reading every license plate that comes into view of the cameras. Whenever Enforcement Deputy needs to look up whether a vehicle is allowed to use a bus lane or park in a restricted area, it identifies that vehicle using the attached plate number. Whenever Enforcement Deputy detects a traffic law violation, the evidence package includes not just the plate number but also a cropped image of the plate itself.

In addition, Enforcement Deputy offers ANPR lookup. This feature looks up every plate number on lists of Vehicles of Interest (VoI) that are stored both inside the system and on external servers maintained by law enforcement. If the plate number is found on one of these lists, a video recording is made of the vehicle’s presence and the officers on duty are immediately alerted.

ANPR lookup helps catch wanted criminals, find stolen cars, and identify unlicensed or uninsured vehicles.


Why do I need this?

License plate data  is streamed to the central command station, where it is used to build a database of cars and their locations for real time crime investigations. The combination of ANPR and geographical meta-data allows the system to correlate positional frequency, which could be a factor in identifying potential criminal activity (for example, when the same vehicle is identified making numerous runs around a local bank).

Furthermore, incoming ANPR data is compared in real time to a database of known license numbers. When a match occurs, any relevant information – for example, if the car is stolen, the driver is a wanted suspect, his license is suspended or insurance is unpaid – is relayed to the officer in the field, who can then take whatever precautions are necessary to approach or apprehend the driver of the blacklisted vehicle. In this manner, ANPR functionality provides the combined benefits of data collection, crime prevention and enhanced protection for officers in the field.
