Zones

Zones allow you to define a specific area of the frame and apply additional filters for object types so you can determine whether or not an object is within a particular area. Presence in a zone is evaluated based on the bottom center of the bounding box for the object. It does not matter how much of the bounding box overlaps with the zone.

Zones cannot have the same name as a camera. If desired, a single zone can include multiple cameras if you have multiple cameras covering the same area by configuring zones with the same name for each camera.

During testing, enable the Zones option for the debug feed so you can adjust as needed. The zone line will increase in thickness when any object enters the zone.

To create a zone, follow the steps for a "Motion mask", but use the section of the web UI for creating a zone instead.

Restricting zones to specific objects

Sometimes you want to limit a zone to specific object types to have more granular control of when events/snapshots are saved. The following example will limit one zone to person objects and the other to cars.

camera:

record:

events:

required_zones:

- entire_yard

- front_yard_street

snapshots:

required_zones:

- entire_yard

- front_yard_street

zones:

entire_yard:

coordinates: ... (everywhere you want a person)

objects:

- person

front_yard_street:

coordinates: ... (just the street)

objects:

- car

Only car objects can trigger the front_yard_street zone and only person can trigger the entire_yard. You will get events for person objects that enter anywhere in the yard, and events for cars only if they enter the street.
