Up to 8 circular zones can be defined identified by latitude and longitude of the center, with the dimension of the radius defined in meters.

The surveillance of a zone is activated by setting its radius.

Specific events are triggered when the device enters and leaves the defined perimeters.

The event is detected when the position is evaluated, so it depends on parameter G08 which sets the update rate of the position in the range from 1 to 65535 seconds.

Deactivated zones do not produce events

The rules for geofence surveillance are stored in

specific unit R folder
