[Config Support]: Frigate not detecting persons

[jutuahol]

Describe the problem you are having

I'm encountering an issue where, when using the main stream for detection, Frigate no longer detects persons. In the debug view, a red box appears, indicating that motion is detected, but it fails to recognize persons. Person detection operates correctly with the sub-stream (640x360). Down scaling main stream for example to 1280x720 wont make any change.

I'm uncertain whether this problem stems from the camera or an incorrect configuration. Currently, I'm running Frigate on an Ubuntu VM under TrueNAS Scale.

the problem is your filters, 10000 max area for person is way too low after you increase the detection resolution

Thank you, now it works perfectly. One becomes blind to simple things after banging one's head against the wall for long enough.

I had some problems with the detect stream lagging by about 20-30 seconds over 24 hours, so I need to try with the main stream.
