Do you mean the Camera's zone map? I made that full screen and the yellow box still tracks "behind" the car and the plate. It's like a search area that isn't big enough

Have you tried creating two zones (left third and right two-thirds) and using a crossing from right to left as the trigger to search for a plate?

I agree that more zoom would help give the license plate model a better chance to see a plate.

You could define the area of interest (AOI) on the video tab. However, if you define the AOI, you might want to clone the camera so that you can capture both front and rear plates.

I'll give that a shot, the issue seems to be that the yellow overlay box that shows you motion tracking, doesn't cover the front license plates for oncoming cars. I'll zoom in a bit on the street, my concern with too much zoom though is that the car will pass too quickly and then miss the track

When AI is looking at the image it is not just looking at the section that has motion (the yellow box). It looks at the whole image/zone minus the sections that are optionally configured to be blacked out (which is maybe what you did with the non-road sections there on the top left and bottom right).

I agree with Vettester in that you need to zoom in more.

Open the video for playback and turn on "Analyze with AI" and you will see what I mean. Don't forget that even if it finds a plate it needs to be big enough to read it. I can't even read a single digit on the plate in you example. You look at Vettester's image and you can read the whole plate.

OK, I do have plenty of zoom on this, but it won't capture both sides of the street then
I'll have to buy another

With that camera you should be able to capture both sides of street. Here's an example of the zoom level I'm using and I get both side of the street. I do have two cameras because front plates are not required where I live.
