License plate recognition (LPR) and vehicle access control with AI

Mercosur and older Brazilian plates read on your cameras, with an authorized list, alerts, a searchable history with images and gate integration.

01The problem

Gatehouses write plates down by hand or rely on cameras that don't read anything; there's no reliable entry and exit history and no alert for unauthorized vehicles.

02How we solve it

Computer vision models (detection plus OCR of plate, make, model and color) running at the edge or in the cloud on your existing cameras, with an authorized list, alerts and a searchable history.

03How it works

01Camera02Model reads03Rules check04Gate and history
  1. Camera

    A camera positioned at the entrance captures every vehicle.

  2. Model reads

    Computer vision reads the plate (Mercosur or older format), make, model and color.

  3. Rules check

    The plate is compared with the authorized list and the time rules.

  4. Gate and history

    The gate opens or an alert goes out, and everything is logged with an image.

The highlighted step is the check: anything that fails the rules goes back for review instead of moving on.

04What changes in practice

  • A history you can rely on. Every entry and exit recorded with plate, time and image.

  • Instant alerts. A vehicle that isn't on the authorized list triggers a warning right away.

  • Cameras put to use. Many existing cameras work with adjustments to position and lighting.

05What you get

  • Plate reading on the agreed cameras
  • Authorized list and alerts
  • Searchable history with images
  • Integration with the gate or gatehouse system

What we measure

  • correct read rate
  • passage time
  • unrecorded events

Metrics are agreed before we start. With the numbers in hand, you decide whether to move to production.

09Frequently asked questions

How much does a license plate recognition system cost?

Every project is quoted after a free assessment, based on scope, volume and the systems involved. To start with a fixed scope, the “License plate recognition proof of concept” offer starts at US$ 1,600 and takes 3 weeks. You get a fixed-price proposal in writing before any work starts.

How long does it take to install plate recognition?

The pilot takes 3 to 6 weeks. Typical scope: 1 or 2 entrances with a suitable camera.

Do I need new cameras?

Not always. We assess position, resolution and lighting; many existing cameras work with adjustments.

Does it work at night?

Yes, with an infrared camera suited to the reading point.

Does it read both the older plates and Mercosur plates?

Yes. The model reads both Brazilian formats, and the pilot measures the accuracy on your cameras.
