Q-Free

Read every plate. Run no infrastructure.

ALPR delivered as a remote managed service.

Submit an image to Intrada Cloud and get an accurate license-plate read back. Q-Free runs the recognition, the scaling, and the plate library — so you build on the result, not the pipeline.

What it is

Automatic license-plate recognition, delivered as a service.

Traffic products, enforcement systems, and access solutions submit images to the cloud and receive highly accurate recognition results — with no need to deploy or maintain recognition software or server infrastructure.

Q-Free manages scalability, availability, and continuous plate-library updates across more than 200 countries and states, with formats updated automatically. Optional analytics add vehicle make, model, class, and color, plus dangerous-goods signage identification.

Where it runs

One service for every deployment.

The same API backs a roadside camera, a parking barrier, and a phone in the field.

Roadside & enforcement

Cameras submit images directly and act on the returned plate read for surveillance and enforcement.

Back office

Existing workflows send stored images to the cloud and feed recognition results straight back in.

Parking & access

A camera at the barrier sends each vehicle image and opens the gate based on the plate read.

Mobile app

An image captured in the field is submitted to the cloud for an instant recognition result.

Why teams choose it

Recognition you adopt, not operate.

  • 01

    Adopt without infrastructure

    Add plate recognition to your product without local video processing, scaling, or availability to manage.

  • 02

    Unmatched read accuracy

    Reliable reads in poor light and challenging weather conditions.

  • 03

    Beyond the plate

    Determine make, model, class, and color to aid surveillance, enforcement, and tolling or road-user charging.

  • 04

    Scales without re-architecting

    Go from a single site to a nationwide program on the same service, unchanged.

  • 05

    Flexible pricing

    Pricing schemas that match any project and budget, from one project to a global rollout.

How it works

Image in, structured result out.
