[Support]: High CPU Utilization and Motion Detection Too Sensitive

Describe the problem you are having

After updating from 0.9.4 to 0.10 the cpu utilization increased significantly and the number of motion boxes appears to be the reasons. The increase in motion detection is happening on all four cameras. I’m using the default values for all motion parameters on both versions.

Looking for suggestions/settings to get the motion detection on version 0.10 closer to 0.9.4.

Motion boxes on version 0.9.4: Same view showing increased number of motion boxes on 0.10. It is very overcast today with no wind. When sunny there are 30 to 50 motion boxes in this view: On version 0.9.4 cpu utilization at 41%:

On version 0.10 cpu utilization at 102% and goes much higher on sunny day:

The problem I was having restoring the 0.9.4 backup was resolved by updating to Supervisor version 9.3. This is troubling since I hadn’t made any changes to anything on HA except switching back and forth between Frigate versions. So the backup stopped working due to some change that was made external to my system. I’ve started making image backups.

Frigate version 10.1 certainly has solved the increased motion sensitivity issues that I was having. I have been able to use the motion parameters from version 0.9.4 with excellent results. I’m having some problems with stationary object detection, but will open another issue to address those.

[blakeblackshear]

Assuming the resolutions are the same, with 0.9.4 your previous motion settings would have been calculated as:

frame_height: 360
contour_area: 400

However, reverting to these values won’t match the same behavior due to the new dynamic contrast.

I would recommend the following:

1. Try increasing your contour_area. If you find that small objects are not being detected as motion, reduce that number back to the default.
2. Try increasing your threshold. If you start missing motion, that means the difference in the pixel values isn’t enough to cross the threshold.
3. You could also see if your cameras support Wide Dynamic Range (WDR) and enable that. It should increase the contrast on the camera dynamically which would reduce the amount Frigate dynamically adjusts contrast.
4. As a last resort, try increasing the frame_height and contour_area together while keeping the contour_area roughly the same % of the total pixels of the frame resolution.

Also, thanks a ton for the well crafted issue. Much appreciated.
