By default, the entire FoV is a scene analytics zone. If you need to exclude parts of the scene prone to false alarms from detection (leaves, water, etc.), you should set privacy masks - zone with scene analytics and metadata generation disabled

To do so, follow the steps:

1. Select the Object Tracker object and click the  button.

2. In the FoV, set the nodes of the closed area, in order, inside of which you want no detection.

   

   When the area is being constructed, the nodes are connected by a two-color dotted line which outlines the area's borders.

   For your convenience, you can click the  button and configure the mask on a still frame / snapshot. To undo, click this button again.

   Action	Result
   Click in the viewing tile	Creates a new area node
   Right-click on a created node	Deletes the area node
   Position the cursor on a node and hold down the left mouse button while you move the mouse	Moves the area node
   Click the  button.	Deletes the area

   Once the area is closed, you will see the  buttons on the borderlines. If you click them, a new node is added. This allows you to be more flexible with zoning. 

3. Set the required masking areas.

4. Click the Apply button.

You have successfully created the detection zone.
