2 years ago Will need to see screenshot of the camera along with the object mask and then the event snapshot (with bounding box).
If an object is masked then it won't create an event at all if it doesn't move, but if it moves outside of the mask then it will create both snapshot and clip (depending on rules). Odds are the mask is defined incorrectly (remember that an object is only masked out if the mask covers the bottom center of the bounding box) and then the default motion for recording retain mode meant that the segment wasn't saved so no clip was created. Screenshots mentioned above will help confirm or deny this idea.

Describe the problem you are having
I'm having a hard time using object filter masks to filter out false positives in a specific area of my camera. I created a mask on a camera and it seems to be discarding clips that contain false positives, but still creating the events themselves in Frigate. I'm not sure if this is a feature or a bug, but I'm trying to get it to where it doesn't create an event at all for false positives, but does create events (with clips) for true hits (active object)
I do NOT want 24/7 recording and I do not want Frigate to capture all motion - all I want Frigate to do is to create events/snapshots/clips of specific objects when detected.
My real-world use case I have a computer desk in a room which sometimes has a person working at it. I don't want Frigate to create events when that person is at their desk, even if they are moving around within their desk chair. I DO want Frigate to detect other person motion events in other areas of the room and to fire events and to capture clips. I DO NOT want Frigate to do anything (events, snapshots, clips, etc) if there is non-person motion or if the person motion is a false positive.
I've set up my object filter mask to surround the desk area. I'm capturing plenty of events of people walking in other areas of the room and it is correctly saving motion clips and snapshots of this activity. The problem though is that I am still capturing events and snapshots (but not saving clips) of motion within the desk area. In a few cases I'm also getting events (with snapshots but no video clips) of the person leaving the desk area where they should actually be captured as a person motion event. I'm unsure if Frigate thinks this is a false positive or if there is some other issue saving the clips.
I'm including relevant pieces of my configuration as well as log output from one of the recent events that was captured missing a video clip. Any suggestions are appreciated!
