Describe the problem you are having

I am facing an issue where alerts are being generated for detections outside of a zone. I have the Driveway camera set to alert within the zone Driveway_Main and every other detection will show regardless of zone (but won't alert).

The detection's bounding box was well outside my defined zone; however, an alert was generated.

I have attached some screenshots.

If I had to guess, the car there had a few frames where the box was incorrect and considered part of the zone leading to the alert being generated. In 0.15 this type of thing will be much easier to debug and see what happened.

What would cause the car to have an incorrect bounding box? I've noticed on some alerts, particularly those at night when the camera is in IR mode, the bounding box is very large.

I also get a lot of alerts during rapid scene changes with stationary objects. Eg clouds passing over, shadows, sunset etc.

likely just an issue with the default model since it is not trained on security camera images. Could be filtered out with max_area filter.

Thanks. I'll work on my Frigate+ model training.
