[Support]: High detect CPU usage

[ehn]

Describe the problem you are having

I'm constantly getting an alert in the Frigate web UI footer for one of my cameras, complaining about high CPU usage (45%). I have two cameras of this type. They're configured identically. I only get this complaint for one of them.

Possibly the high CPU usage could be caused by a specific scene with lots of motion, say leaves moving in the wind. However, they're PTZ cameras, and I've tried pointing them at various things. It makes no difference. I keep getting this notification for one of them and so far never for the other.

The system view is also showing high detect CPU usage for this camera:

Have you tried using the new Motion Tuner (Settings --> Motion Tuner) to adjust your motion detection settings?

https://deploy-preview-11419--frigate-docs.netlify.app/configuration/motion_detection

[NickM-27]

It can stay for up to a minute depending on when the UI was first opened.

[ehn]

And I guess more than one camera can potentially generate the condition for such a warning? Would then only the one with the highest current CPU usage be shown?

[NickM-27]

any camera that meets the threshold will have a warning shown

[ehn]

So there can be more than one warning shown at a given time?

[hawkeye217]

Yes.
