[Config Support]: Objects outside the Zone are getting detected and reported

[Jebarson]

Describe the problem you are having

I have a camera configured so that only alerts are raised when there is a detection inside the zone. I believe that my setting is perhaps wrong.

I'm not quite sure what you're asking or looking for.

Do you want alerts only for objects inside the Front zone?

[Jebarson]

That is correct.

[hawkeye217]

Go to Settings --> Camera settings in the UI. Select your camera in the top right. Check the box for Front under Alerts.

[Jebarson]

Ah ha, this is what was required, i guess. Thanks Josh, I will mark that as an answer once I verify.

      alerts:
        required_zones: Front

[hawkeye217]

Be sure to restart Frigate for those changes to take effect.

[Jebarson]

There are some alerts but i guess they are perhaps due to the way frigate operates and thinks they crossed the zones

[hawkeye217]

Don't forget that an object is considered in a zone if the bottom centerpoint of its bounding box is in the zone. See the example in the zone docs here: https://docs.frigate.video/configuration/zones/
