Voyent Alert! accomplishes this through its enhanced geofencing system. During the registration process and at any time after, citizens can add map pins for their most common locations. This can be their home, children’s school, places of work, or even their family and friends.

If an incident arises in an area of your jurisdiction in which citizens have placed these map pins, any alert that you create will be immediately distributed to them and only them. Using the advanced map definition feature, you can not only specify which areas are of immediate concern, but, as in the case of a wildfire evacuation order, set thresholds that extend outward from the location of the fire. 

For example, citizens within five kilometers could be placed under an “evacuate immediately” alert, while those between five and fifteen kilometers could be sent a different alert advising them to prepare to evacuate.

In the above example, those outside of the alert radius can either be sent a message to make them aware or the incident, or a warning alert can be triggered when their mobile device enters the alert zone.
