[Config Support]: person detection only in zone

[ViezeVisNL]

Describe the problem you are having

Hey!

My Reolink Doorbell POE is running fluently on Frigate now. But what I noticed is that the person detection happens even outside of the zone. And if I make a motion mask in the middle of the screen I am afraid the camera might not be detecting persons quick. I am using the entity 'camera.reolink_person'.

Can I set my config so only person detection happens in the zone only, instead of outside the zone? See the example here.

You can see a person here:

You can see the motion- and zone masks here.

I thought with my config setting snapshots enabled only to the 'zone_voortuin' it should not trigger snapshots outside of this area. But I might misinterpreted that. See my config. I removed go2rtc, model, detector, mqtt part.

If you see any other strange things just let me know. Thnx !

you need to make the zone required for snapshots and recordings https://docs.frigate.video/configuration/zones#restricting-events-to-specific-zones

also using motion masks like that is discouraged and not how they are supposed to be used

[ViezeVisNL]

@NickM-27 I miscopied my config. It is listed. The Motion Masks should only be used for the false-positive regions such as plants etc?

The Motion Masks should only be used for the false-positive regions such as plants etc?

motion masks are not used for stopping objects from being detected, they are used for blocking out areas of motion that are not going to have objects. For example the sky, timestamps, tops of trees, etc.

[ViezeVisNL]

@NickM-27 Check. Will dive into that later. But based on the config above you'll see the required zones are listed under record & snapshots. Is that what it should be?

[NickM-27]

Yes, so frigate thought that object entered the zone. In frigate 0.13 there have been many changes and improvement to the zone behavior as well as the ability to see the moment that the object entered the zone.

[ViezeVisNL]

Ok, thanks. Ill update once available. But before that I'll connect a Coral. Currently running on CPU but managed to get a USB Coral :-)

Thanks!

[ViezeVisNL]

And Ill have a look at the motion masks. Are motion masks related to performance or not specific?

[NickM-27]

Generally they are to reduce wasted cpu usage in motion that won't be related to objects.

[ViezeVisNL]

Thanks. You may close this case.
