What does your m ffmpeg options look like? I have the firmware on a v3 not very close to access point and works fine with frigate/HA. Also, what fps are you using in frigate.yaml? I run 5 fps @ 1920x1080
ffmpeg:
global_args: -hide_banner -loglevel fatal
output_args:
record: -f segment -segment_time 60 -segment_format mp4 -reset_timestamps 1 -strftime 1 -c copy -an
