What is geofence?
Geofence is a virtual fence (a circle around certain location) that you can preset online. When the unit enters/leaves the fence, you receive an alert via email or phone SMS message. You can also set alerts for "inside fence for X minutes".
For example, you set a geofence named "School" as a 3000 feet circle from the center of the school. When your child carrying the unit leaves this circle, you receive an Email or SMS saying "Joe leaves school at 5:30PM".
Don't set the fence radius less than 500 feet because with small fences the GPS signal fluctuation may trigger false alarms.
Time Based Geofence
Geofence can be setup as being active during a certain time range only. For example, a "School" fence can be active between 7am and 4pm only. To setup time based fences, go to your "Account" page, then click "Manage Fences" link and enter time range in the "Time range" field.
