# Geofences

# Geofences



| This module is an optional [extension](/en/article/extentions-1j4jgcx/) and has to be activated first.

GroupAlarm offers two application options for the use of geofences:

## Geoalarm

With geofences, you can specifically alert employees and emergency forces who are in a defined area or region. 

Optionally, participants located within a geofence can be alerted with increased priority. If the desired strength cannot be achieved in this way, the alerting is escalated to emergency forces outside the geofence.

## Geo-availability

If you as a staff member or emergency worker only want to be alerted when you are at a specific location, you can use this function to link your availability to a geofence.
