Zones, masks & lines

Zones let you control where detection happens, hide parts of the frame, and detect when something crosses a line. You edit them per camera, and they act on the camera's detection, so it needs detection set up.

Opening the editor

Open a camera's settings, go to the Settings tab, and select Edit zones under Zones. The editor opens over the camera image with two tabs: Zones and Lines.

Detection zones

On the Zones tab, draw a polygon by adding points on the image. A zone limits where detections count:

• Include. Only detections inside the zone trigger.
• Exclude. Detections inside the zone are ignored, for example a busy road or a swaying tree.

You can limit a zone to specific object types (its labels), so it reacts only to people or only to vehicles. Intersect mode triggers when a detection's box merely overlaps the zone, instead of needing its centre inside.

Privacy masks

Turn a zone into a privacy mask to black out part of the frame. Masked areas are hidden in live view and recordings, which is useful for a neighbour's window or a public sidewalk. A privacy mask only hides; it has no detection settings.

Lines (line-crossing)

On the Lines tab, draw a line across the image to detect when something crosses it. Each line has a direction:

• A → B or B → A triggers on a crossing in one direction.
• A ↔ B triggers in either direction.

Like zones, a line can be limited to specific object types. A crossing fires an event only when something actually moves across the line in the chosen direction, so you can alert on someone coming through a gate rather than just appearing in view.
