Geofences are geographical zones that can be used to generate events about device movement in and out of the zone.
There are three supported geometry types:
If a geofence is linked to a device, it means that the system will monitor device entering and exiting that geofence.
If a geofence is linked to a group, it means that the system will monitor all devices in that group entering and exiting the geofence.
If a user has access to a geofence, it means that the user can edit/remove the geofence and can subscribe to the geofence events.
Calendars can be linked to geofences. It will limit events generation to the calendar schedule.
Distance around a polyline geofence, when device is considered inside the geofence, can be configured with the geofence.polylineDistance configuration parameter (25 meters by default).
The color of a geofence on the map can be set in the geofence attribute color. Any valid HTML colors are accepted.
If you need control device movement along a predefined route, you can use a polyline geofence. Also, if you need control when a device started and ended the route, you can add additional geofences at the start and at the end.
