[Config Support]: Config file hierarchy for zones, object restriction and recording

[ChienDeLaCasse]

Describe the problem you are having

Greetings,
I am trying to implement specific zones for object detection (or is it rather tracking ?). I did my best at reading Frigate documentation for zones, full reference config template, and similar discussions.

But unfortunately, my config file seems incorrect and Frigate keeps loading.
Could you kindly correct the following assumptions ?

1. Zones for restricting object detection are defined inside the "[name_your-camera]" level. Not anywhere else. (ERGO : no possibility to define a common zone for all cameras (inside "cameras" level or global above).
2. Any such object restriction is defined inside a [name_your_zone]. Not anywhere else.
3. To make use of the zones, they are listed under "record->events->required zones/snapshots" section. Not anywhere else.
4. The above settings (if correct) override the "objects->track" at the "[name_your_camera]" level, and thus at the "cameras" or global leveL

May I kindly ask what is wrong in my config file ?
Many thanks !

Zones for restricting object detection are defined inside the "[name_your-camera]" level. Not anywhere else. (ERGO : no possibility to define a common zone for all cameras (inside "cameras" level or global above).

you absolutely can define zones for all cameras, though IMO this is very uncommon as it is not likely that the same shapes will exist on each camera

Any such object restriction is defined inside a [name_your_zone]. Not anywhere else.

again, this can be set globally if desired

To make use of the zones, they are listed under "record->events->required zones/snapshots" section. Not anywhere else.

that is how you apply them to events, they can also be useful outside of frigate, for example for notifications

The above settings (if correct) override the "objects->track" at the "[name_your_camera]" level, and thus at the "cameras" or global leveL

No, object -> track is separate and is not related to zones directly. If you list an object as possible for a zone it must also be listed as an object that is tracked otherwise, how would frigate know if the object is in a zone if it is not detecting it?

Thank you so much for your prompt and clear reply! I added objects-track at the global level and Frigate runs again.
