Double Line Crossing - D-Link DCS-F Series User Manual

Camera User Manual
NOTE
Try to draw the single line crossing in the middle, because the recognition of a target takes time after target
appearance on the screen and an alarm is generated only when the object is recognized to have crossed the single
line crossing.
The single line crossing which detects person foot as the recognition target cannot be too short, because a short
single line crossing tends to miss targets.
