      • to rotate the zone, drag it, while holding the mouse pointer close to the inner perimeter of the zone;
      • to move the zone around the frame of the video image, use a dotted line circle (4).

   4. Specify the approximate size of the vehicle in each surveillance zone by changing the size of the internal areas in the bottom left corner of the zone (5). This field is called the detection area.

      Info
      title Note
      Each surveillance zone over its entire area is proportionally covered by detection areas of the specified size. It is necessary to set the approximate dimensions of the vehicle so that each surveillance zone includes no more than 256 detection areas. To control the coverage of the zone with detection areas, use the debug window (see Appendix 1. Debug window). The stopped vehicles can be detected only in those parts of the surveillance zone, which are covered with detection areas.
