Polygons and Best.jpg images are not working

Describe the bug When I add a polygon to the zone of the camera entity, they are not followed and I have detections even outside these polygons.

Config file

zones:
  front_steps:
    coordinates: 1149,183,4,763,4,1078,1919,1078,1914,448,1588,363,1419,327,1156,276,1147,207

Another question is that the best.jpg file is not created. I’ve enabled the settings snapshots like this

snapshots:
  show_timestamp: True
  draw_zones: False
  draw_bounding_boxes: True

And also the main configuration for the paths

save_clips:
  clips_dir: /home/coral/video
  cache_dir: /home/coral/cache

What else do I miss?

I fixed the config he posted on the issue. Also, zones do not prevent objects from being detected outside of the zones. They only create a sensor to tell you when an object enters the zone.

I think your issue is a result of https://github.com/blakeblackshear/frigate/issues/261#issuecomment-715986761

Please give that image a try and dont forget to set your shm_size appropriately.
