Configuring a detection area

By default, the entire frame is analyzed. If you want to analyze only a certain area, you must specify one or more areas where detection and metadata generation will be performed.

To do this, do the following:

Select a detector and click the button.
In the Surveillance window, click the mouse button.
Select Detection area in the list.

In the Surveillance window, set the anchor points of the area, within which the detection will be performed.

Note

Depending on the detector being configured, the area can be either rectangular or polygonal.
When you set anchor points, they are connected by a two-color dashed line outlining the border of the area.
For convenience of configuration, you can "freeze" the frame. Click the button. To cancel the action, click this button again.
Once the area is closed, the buttons are available on its borders between the anchor points. When you click them, a new anchor point is added, allowing you to specify the most precise areas possible.
To delete a selected area, click the button.

Specify all required detection areas.
Click the Apply button. To cancel the changes, click the Cancel button.

Configuration of a detection area is complete. Detection areas are relevant for all sub-detectors (except for Line crossing) created on the basis of the parent detector.
