Set up Geo-Fence Coordinates
A Geo-Fence is a virtual perimeter for a real-world geographic area.
Geo-Fencing is a term utilized primarily in the corporations that refers to the practice of limiting mobile employees to a
specific geographic location by tracking their whereabouts via the GPS. The purpose of geo-Fencing is to ensure a
company’s mobile employees travel locally or drive company vehicles as part of their job, stay within the boundaries the
company deems productive. It is essentially another way for large corporations and businesses to monitor their
employees’ actions at work.
User can set up the Geo-Fence coordinates by entering SMS command below. The Geo-Fence coordinates (gf1~gf10) are
defined as a round (circular) area. Therefore, the coordinate is the center and the radius is defined in meter.
There are totally 10 groups of Geo-Fence coordinates can be set and saved.
