Different retention policies for the same camera based on zone

[ediguidedog]

Describe what you are trying to accomplish and why in non technical terms
I want to be able to have different retention policies for the same camera based on zone. In other words my front camera covers both my front garden and the street and I want to retain any activity in my garden for 21 days. However being a nosey good neighbour I want to keep an eye on the street but only want to retain the recordings for say 3 days.

Describe the solution you'd like
Additional configuration options to define the retention period based on zone & object rather than just object types

    record:
        events:
            required_zones:
                - the roadway
                - my path
            objects:
                - person
                - car
            retain:
                zones: 
                    the roadway:
                         objects:
                             car: 2
                             person: 3
                    my path:
                          objects:
                            person: 21

Or another way if better as this may well lead to an exponential growth of the config files

Describe alternatives you've considered
I can do this with a second camera utilising the rtmp feed from the first camera but it's messy and increases the processing load

Additional context
Hopefully this helps if I haven't explained. I want to retain events in my property for one period and outside retain for a different period

How do you suggest this works if an object is detected in multiple zones?

I agree that exponentially growing config file is a concern, the request makes sense though

I guess the longest zone retention policy would win. So to use my examples
If someone was just in the roadway it would be 3 days but if they then stepped foot onto my path it would increase to 21

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

Found this after searching for the same feature, here's another vote in support of zone specific retention configuration.

For what it's worth, I would like to see this implemented as well, with pretty much the same use case as the OP.

Also interested in this for the same reason. Would like to retain events from the street for a shorter duration than events that take place on my property. Currently I don't create a zone off property like the blue region in OPs screenshot as I don't have enough storage to retain events for a long period as they are much more frequent due to cars, etc.

I would also like to set different pre_capture/post_capture per zone.

I would be interested in this as well for the same reason. Currently only retain about 10 days of events but would probably keep the street retention even less.
