3.5.1.1 Cross Line
Cross line detection generates an alarm when an object moves past the detection threshold
in the direction you defined. Up to 4 detection lines can be added. Note that when adding
multiple detection lines, make sure they do NOT intersect as it may affect the detection
results. Select the checkbox next to Cross Line to enable and click
to configure.
