Draw Zone or Trigger Line for Radar

You can draw zones or trigger lines for radar, so if an object is detected to have crossed the trigger line or entered the area shaped by the dual-trigger line or zone, the event and alarm will be triggered.

1. In the top left corner of Home page, select > Visual Map > Map > Map Settings.
2. Click the radar's icon on the map and then select Draw Zone/Trigger Line from the drop-down list to start drawing zone or trigger line for radar.
3. Select a zone drawing method in the tool bar in the upper-left corner of the map.

   Draw Trigger Line

   A trigger line is a virtual line drawn in the radar's detection area. An event or alarm will be triggered if an object is detected to have crossed the line. Click to draw a trigger line in the detection area. Select a direction for the trigger line. The three directions indicate three directions to which a detected object crosses the line. You can drag the anchor (the red point on the trigger line) to reshape the trigger line, or drag the trigger line to move it to another place.

   Note:

   No more than 4 trigger lines can be drawn.

   Draw Dual-Trigger Line

   A dual-trigger line consists of 2 virtual lines drawn in the radar's detection area. Generally, it is used to mark an area in the radar's detection area. An event or alarm will be triggered if an object is detected to have entered the area shaped by the dual-trigger line. Click to draw a dual-trigger line in the detection area. Select a direction for the trigger line. The three directions indicate three directions to which a detected object crosses the line. You can drag the anchor (the red point on the trigger line) to reshape the dual-trigger line, or drag the dual-trigger line to move it to another place.

   Note:

   Only 1 dual-trigger line can be drawn in the radar's detection area.

   Manually Draw

   You can draw any shape for the zone using this method.

   Zone Segmentation

   Split a zone into two smaller zones by a line.

   Distance Segmentation

   Split a zone into two smaller zone by an arc.

5. Set parameters for the drawn trigger line or zone.
6. Click Save.
7. Right click to exit the zone or trigger line drawing mode.
