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.
