[Support]: zone based object detection not working

[lcasale]

Describe the problem you are having

I'm trying to break my driveway camera into zones to avoid vehicle detection on the main street. However, only the person object is being applied to the camera and zones unless I add vehicle tracking to the camera level but then it's not restricted to the zone I want to track vehicles. I've mimicked the configuration here but it doesn't seem to be working.

You have to list all objects you want to track at the camera level. Just adding them at the zone level won't do anything if the camera isn't set to look for those objects.

With the config you posted, you should only get events of vehicles if they enter the driveway_end zone.

I originally had them in the camera object (below), but I was getting vehicle alerts outside of the driveway_end zone.

objects:
      track:
        - vehicle
        - bicycle
        - person
        - animal

If you can provide a screenshot of the camera with the zone along with examples of vehicles outside the zone then we can help give guidance. You may know this but do keep in mind that zones are triggered based on the bottom center of the objects bounding box.

Ahh that's what's going on. The street is on an angle so the bottom of the bounding box was clipping the zone thus triggering. Thanks for the quick replies!
