Automatic License Plate Recognition solution.


TREX-PARKING is an Automatic License/Number Plate Recognition (ALPR/ANPR) solution that logs and controls the access of the vehicles.

TREX-PARKING is a flexible and modular solution that uses the latest technologies of high-resolution digital cameras and LED illuminations. It is accompanied by a powerful software suite with an intuitive and customizable graphical interface.

As a vehicle arrives at a checkpoint (gate, barrier, weighbridge…), the system automatically captures and recognizes in real time its license plate. A customizable scenario queries the database to determine if the vehicle is authorized or not to enter, and to get more information about the vehicle (model, type, owner…). The scenario can also trigger automatically actions based on the license plate recognized such as opening a gate or barrier, controlling a traffic light, sending an audible or visual alarm to an operator...

All data collected during transaction are stored in an SQL database using a secured web service or can be exported to XML files... TREX-PARKING can easily exchange data with a ticketing machine, a pay station, a car park management system, a weighbridge, an X-ray inspection system, or any other external system.

TREX-PARKING is the ideal solution to ensure an efficient access control and the tracking of the vehicles.
