Line Crossing Counting
Users can draw detection lines to count the number of people entering or exiting.
- Ensure that the detected target can pass through the detection line completely.
It’s recommended that the detection line is perpendicular to the In/Out
direction and on the center of the detection area without other objects around.
- Redundant identification spaces are needed on both sides of the detection line for the target detection. This ensures stable target recognition and tracking before crossing the detection line, which will make the detection and count more accurate.
- It is recommended to draw the detection line as close to the center of the image as possible, and ensure that the target has already been detected before crossing the line.
Step 1: Please ensure that the deployment parameters and device strategies have been configured before using this feature.
Step 2: Find the list of detection lines. Click +Add to draw a new
detection line or click
to edit the existed detection line on the live
view.
Step 3: Left-click to start drawing and drag the mouse to draw a line, left-click again to continue drawing a different direction edge, and right-click the mouse to complete the drawing. The line can be dragged to adjust the location and length. One device supports at most 4 broken lines with maximum each.
Step 4: If users want to redraw this line, click Clear This Line or drag
the vertices of the broken line to adjust. The arrow direction of the detection line
depends on your drawing direction. If users need to flip the line, click Flip Direction.
Then click 
to finish drawing.
Step 5: Users can click
to customize the name of line. If
users need to delete a certain line, click
