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