@Nunofya It's on BI settings with CodeProject.AI logo on the right

See your screenshot, it's underneath the "Face recognition" checkbox

I also noticed you are using alpr as a custom model. Is there even an alpr custom model available? Try using license-plate.

Here's how mine is configured:

Should "Cuda true" be green? Don't have a dedicated gpu.

Did you uncheck "Only for confirmed vehicle alerts"?
That was it. It appears to be duplicating the license plate number in the alert image. Is there anyway to stop this?

UI3 only shows the one plate
After watching this for a few hours I noticed that I'm missing a lot of plates that clearly should have been recognized. Switching back to the license-plate model seems significantly more reliable.

It should not make a difference because the ALPR module uses the license-plate model to find the plate before it does the OCR. Post a screenshot of your camera's AI settings

Python:
            start_time = time.perf_counter()
            detect_plate_response = await module_runner.call_api("vision/custom/license-plate",
                                                                 files={ "image": image_data },
                                                                 data={"min_confidence": opts.plate_confidence})
            inferenceMs += int((time.perf_counter() - start_time) * 1000)
