After you create and select a line crossing detection tool, you can see a virtual "tripwire" line in the FoV. 

To set up line crossing detection, do the following:

  1. Set up a virtual line in FoV.

    1. Set the end points of the line .

      Note

      When the line is being constructed, the end points are connected by a two-color dotted line. The direction of the object's motion across the line is indicated by dotted arrows.

      Action

      Result

      Position the cursor on an end point and, holding down the left mouse button, move the mouse

      Moves the line end point

      Position the cursor on the line, holding down the left mouse button, move the mouse

      Moving the line

    2. By default, Line crossing detection monitors object motion across the line in both directions. To suspend detection of motion in one direction, click the button  to that direction.

      Attention!

      At least one direction must be selected for detection.

      Note

      An unmonitored direction of object motion is indicated by a dimmed arrow.

  2. If an object in FoV performs repetitive movements near the virtual line, it may cause excessive triggering of the detection tool. In this case, set an area within the object's track which must cross the line completely to trigger the tool. To do it, set the X and Y offset values as percentage of track width and height.

    Here's an example: the green triangle is the track of the object. If you specify X and Y offset values as 25%, the tool will be triggered only if the entire red triangle goes beyond the virtual line.
  3. Click the Apply button.
