Geo-fence of the device has the following two modes: round geo-fence and square geo-fence.
Round geo-fence takes the set coordinates as center of circle and uses the set semi-diameter to determine
fence scope. Square geo-fence uses 4 known latitude and longitude points to determine a square fence.
When the function is activated, once V3338 steps beyond fence scope, it will send positioning information
with the information format returned by above stated “request for single positioning” to the three prestored
numbers. Information status is STATE: OS. At the same time, the first prestored phone number will be called. If it
fails (the phone is turned off or cannot be connected), the second and the third phone number will be called in
sequence.
When V3338 enters fence scope again, it will send positioning information with information format returned
from “request for single positioning” to the three prestored number immediately. Information status is STATE: RS.
At the same time, the first prestored phone number will be called. If it fails (the phone is turned off or cannot be
connected), the second and the third phone number will be called in sequence.
