You can set a detection zone that is common to all situation analysis detection tools.

Detection zones are analyzed by all situation analysis detection tools.

By default, the entire frame is a detection zone. The detection zone is marked with a dimmed green background.

If you need to exclude complex zones in the camera field of view from analysis (leaves, water, etc.), delete the detection zone in the area. To do this, follow the steps below:

1. In the Detection Tools list, highlight a Situation analysis  object (1) that offers a means of analyzing the situation in the field of view of the required video camera.
   

2. In the viewing tile (2), set the nodes of the closed area, in order, inside or outside of which you want to delete the detection zone.
   
   

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

   Action	Result
   Left-click in the viewing tile	Creates a new area node
   Right-click on a line
   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

   You can set only one enclosed area.

3. As soon as a closed area is set, the  icon bar appears for creating and deleting the detection zone inside or outside the area. To utilize an icon's function, click it with the left mouse button. Red icons let you delete the detection zone
   
   

   Icon	Executed function
   	Deletes the detection zone inside the outlined area
   	Deletes the detection zone outside the outlined area

   After you delete the detection zone, the selected area is visualized in the viewing tile as an area with a dimmed red background.
   

Deletion of the detection zone is now complete. To create a detection zone:

1. Select a Situation analysis object. Set the nodes of the closed area inside or outside of which you want to create a detection zone (see steps 1 and 2 in the previous instructions).

2. Use the green icons to create a detection zone.

   Icon	Executed function
   	Creates a detection zone inside the outlined area
   	Creates a detection zone outside the outlined area

3. Click the Apply button.

Creation of the detection zone is now complete.
