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

To do so, follow the steps:

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

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