Set the cordon number and direction. You can add 4 cordons at most.
Direction
：
A<->B, A->B and A<-B optional. It is the crossing direction of the intruder who crosses
over the alarm line.
A<->B
: The alarm will be triggered when the intruder crosses over the alarm line from B to A or from
A to B.
A->B
: The alarm will be triggered when the intruder crosses over the alarm line from A to B.
A<-B
: The alarm will be triggered when the intruder crosses over the alarm line from B to A.

Application Scenario Illustration
1. Auto-focusing function should not been enabled for line crossing detection. If enabled, the video
image will change so greatly that the algorithm will stop working temporarily.
2. Try not to enable line crossing detection when light changes dramatically in the scene.
3. Adequate light and clear scenery are very important to line crossing detection.
4. Adjust the camera to make the detection area in the center of the video image. Make sure no
obstructions are in the main crossing area. It is strongly recommended to make the obstructions (like
trees, bushes, flags, etc.) outside the detection area.
Here we take some improper application scenarios for instance.

Intrusion
Intrusion
: The relevant alarms will be triggered if someone or something intrudes into the alarm areas
or moves in the pre-defined alarm areas.

Event
à
Intrusion interface as shown below.
There are so many trees
near the road and cars
running on the road,
which make the scene
too complex to detect the
crossing objects.
