License plates

License-plate recognition reads plate numbers from vehicles. It builds on object detection: a vehicle is detected, then its plate is located and read by OCR. Enable an AI backend with license-plate support on the camera.

Setup

In the backend's plugin settings, license plates use two models, a detector that finds the plate and an OCR model that reads the characters, plus a confidence threshold. camera.ui downloads them automatically.

Where plates appear

A read plate is attached to its vehicle as an attribute. You'll find it:

• On the event, alongside the vehicle.
• In Recordings, where you can filter by the License plate attribute or search for a specific plate.
• In notifications and AI descriptions, for example "Plate ABC-123".
