Cross line detection
This function can be used to detect people, vehicles and objects crossing a pre-
defined line or an area. The line crossing direction can be set as bidirectional, for
example, from left to right or from right to left. A series of linkage methods can
also be triggered if an object crossing behavior is detected.

To define Cross Line Detection:

2. Check the Enable Cross Line Detection checkbox to enable the function.
3. Click Draw Area . A crossing plane appears on the image.
4. Click on the line. Two red squares appear at each end of the line. Drag one of
the red squares to define the arming area.
