Intrada ALPR

Intrada ALPR is the Q-Free software solution for Automatic License/Number Plate Recognition (ALPR/ANPR). Intrada ALPR offers an SDK for reading registration numbers from images. We offer an API for easy integration with C++, C, C# and other .NET applications.

Intrada® ALPR is already used by many OEM partners and integrators worldwide. Applications range from parking, access control and surveillance systems to speed enforcement systems and tolling systems. Reason to choose for Intrada ALPR is always the combination of accuracy and ease of integration with the availability of any country module and the ability to run on any regular platform.

You can purchase Intrada ALPR licenses as standalone products. When looking for a more long-term cooperation you may also consider becoming an OEM partner for long-term integration into your product range. Application of Intrada ALPR in tolling back offices typically implies tuning and meeting specific level of identification performance. For such projects we refer to Intrada ALPR as part of an Intrada Synergy solution.
