Geo-Fencing
What is Geo-Fencing?
A geo-fence is a virtual perimeter for a real-world geographic area.
Creating a geo-fence allows you to set notifications for when a device
enters or exits a set area.
Setting up Geo-fences for a Sentry via SMS
1. Find the central point of your geo-fence in latitude and longitude. Use a
street address and an online converter (https://www.latlong.net/)
For example: “3A Devon Court, Warwick, Western Australia”in
https://www.latlong.net/ returns a latitude of -31.842190 and a longitude
of 115.802383
2. SMS the Sentry’s phone number to configure your geo-fence:
“0000,B05,Geo-fence number,Latitude,Longitude,Radius,IN Geo-fence
alarm,OUT Geo-fence alarm”
For example: 0000,B05,1,-31.842190,115.802383,50,1,1
This will set geo-fence 1for 3A Devon Court, have a radius of 50
meters,and text your number an entry and exit alarm when applicable.
To delete a geo-fence, SMS the Sentry: “B06,Geo-fence number”
For example: B06,1: This will delete the geo-fence 1and any associated
alerts.
3. When a geo-fence is setup, you will receive SMS alerts that tell you
when a device has entered or exited a designated geo-fence, as well as a
google maps link to the last known device location.
For example: you would receive the following text when the Sentry has
entered geo-fence 1.
(Touching the link in the text For details about what
you receive shows you the this text means, go to
location in Google Maps) Useful Codes (pg 10)
