GPS / GSM / GPRS TRACKER
Send SMS command "nospassword" to cancel the geo-fence.
5.10 MOVEMENT ALARM
Send SMS command "
move+password
" to define a circle (the radius is 500 meters, and the
center
of the circle is the position of the tracker when it received the command), for example
"move123456". You will receive reply as "move ok!" if the setting is successful.
When the tracker moves out of the area, there will be the alarm as "move! + Geo-
info".Send SMS command "password" to cancel the movement alarm.
5.11 OVERSPEED ALARM
Send SMS command "
speed+pspace+speed
" to define a speed limit, for example
"speed123456 080" (suppose the speed limit is 80km/h). You will receive reply as "speed
ok!" if
the setting is successful. When the tracker moves exceeding 80km/h, there will
be the alarm as "speed+080! + Geo-info". It will alarm once for each setting.
Send SMS command "password" to cancel the movement alarm.
(Notice: It's recommended that the speed limit is set at no less than 50km/h, because the
GPS signal may be influenced by clouds etc. So as default we use some kind of speed filter, if
the speed is less than 30km/h, we regard it as zero.)
5.12 LOW BATTERY
When the voltage of battery is low than 3.7V, there will be the low battery alarm, the SMS
format is
"low b Geo-info", and the message sending interval is 30 minutes.
5.13 HOME
Send SMS command "
home+pspace+content
" to insert a content in the message
from the tracker, for example "home123456 gps" then the "gps" will display in all geo-info
from tracker.Usually, we use this function for some advertisement purpose. You can set the
content as the name of your company. You can also set the content as the user's name, for
example if you set "home123456 Becky Li" then you will see from the message that the
tracker's user is Becky Li. Send SMS command "home+pspace+space" to make the
content empty.
