previous versions of frigate worked the same way as many messages are sent. It was never a guarantee that the first message would contain zones. It is generally recommended to check before and after for a different in zones regardless of if the message type is new or update.

You can adjust the zone intertia to affect how long it takes for an object to be considered part of a zone https://docs.frigate.video/configuration/zones#zone-inertia

[mstolpner]

Thank you for such a quick response!

There is definitely a difference after the upgrade from 0.12 to 0.13. With 0.13 I only very seldom see zones in the "new" event. With 0.12 I was consistently getting zones with the "new" event.

Is zone-inertia going to help with a "new" event?

[NickM-27]

I am not saying there is not a difference in the upgrade, I am saying that the core behavior of zones in "new" message has not changed. There was never a guarantee that this would be the case so there is a flaw in the logic requiring the type to be "new"

you could lower inertia but then that would also increase the likelihood of a single frame with a bad box being considered in the zone (which is the reason for the change)

[mstolpner]

Got it, thank you. Having no zones in the "new" events makes it hard to code a notification logic since a simple logic would be notify on "new" events only. I will play with the inertia configuration. I understand that the default is 3.

[NickM-27]

I have a logic that only notifies the first time the object enters a zone by checking that before.entered_zones is empty and after.entered_zones is not

[NickM-27]

which again, is preferable because otherwise you risk missing notifications even with a lowered intertia

[mstolpner]

What if a person enters a "street" zone first (which I do not want to notify on) and then enters "driveway" zone. I understand that the "before" is going to have "street" and "after" will have "driveway" and I will miss this event, right?

[NickM-27]

then you could just check if before doesn't have driveway and after does have driveway

[mstolpner]

Thank you again! I will try to come up with some logic based on your suggestions.
