Set the Rule to Region People Counting.
Select Enable to turn on region people counting.
Click Draw Area to draw the detected area in the surveillance image.
For passenger flow and region people counting, drawing one closed area is enough. The

difference is that an additional direction shall be drawn when counting passenger flow to
differentiate the entry and exit directions.
When drawing the rule direction for passenger flow counting, draft the trigger line from left

to right, with the direction pointing downward.
When drawing the rule direction for passenger flow counting, draft the trigger line from right

to left, with the direction pointing upward.
Draw the trigger line in the image center.

Where only one device is mounted: The length of the drawn trigger line must exceed the

width of the passage.
Where multiple devices are mounted: The drawing of trigger lines cannot circumvent the

coinciding areas of different cameras. Based on actual count data, draft the length of trigger
lines of adjacent cameras to circumvent these coinciding areas as much as possible.
Set up the people counting parameter. See 图 1-1Table 3-1
