2. Password reset
The password is important, because every command you send to the tracker need to end with the password.
The default password is “
123456“, and you may want to change it once you ready to use, to change the password send a message include “
password+old new password” to the tracker.
password123456 567890” will change your password from “
123456” into “
Note: password must be 6 digits long.
For the sake of this tutorial we will change the password back to default.
You can authorize 5 different number on the allow list, so they can command the tracker.
There is two way to authorize, one is calling, number, then this number will automatically became one authorized number.
The most convenient way, send a message in the format of “admin+password cell phone number” to the tracker.
Example: Send “
admin123456 0432733918” will authorize phone number 0432733918 on the allow list.
To remove a number from the allow list then send sms in the format of “
noadmin+password cell phone number“.
Example: Send “
noadmin123456 0432733918” will exclude the number 0432733918 from the allow
If you’re authorising your tracker to call it from outside your own region (or country) then make sure to place the area code or country in front of the number.
Example: If your tracker is located in Australia and you’re calling the tracker from the United States, then you’ll need to authorize your number as “
61432733918“, as “
61” is the country code of Australia.
Australia – 61
UK – 44
USA – 1

4. Auto Tracking
This GPS have the auto tracking function. The command syntax as follow:
t+time interval+time unit+repeat time+n+password”
This syntax seems a little bit confusing, so let me give few example for you.
*Note: In time unit, “
s” stand for second, “
m” stand for minute and “
h” stand for Hours.
Send auto report every 30 seconds, and repeat five times, the command is:
In this example, where 030 is the interval of 30 seconds, the 005 means repeat 5 time, 123456 is the password.
Time interval and repeat time must be in 3 digits length.
If you want to set the auto tracking to report every 1 hours and repeat 24 times. Then send SMS as “
To cancel auto tracking, send “
5. Voice Surveillance
You can set the tracker into monitor mode, when you call the tracker, the tracker will answer your phone and transfer the voice around the tracker back to you.
To set the tracker into voice surveillance mode (monitor mode), send command:
monitor+password“, make sure to set it back to tracker mode once you want it to report geographic info, to set it back to tracker mode send command “
Geo-fence will help you to restrict the target within a certain preset area. When the target breach the restrict area, you’ll get a message report.
Note: You need to let the tracker stay still for 10 minutes before you send the command to it.
The command is “
stockade+password latitude1, longitude1;latitude2, longitude2“
If you are unsure of the GPS coordinates of the zone your are creating a Geo-Fence for, the simplest way is to use Google Maps.
Go to http://maps.google.com, and find the location of the desired Geo-fence you would like to create. In this example we will use the city of Adelaide, South Australia.
Place your cursor over the map and “right click” where you would like the top left corner of the Geo-fence to be… and then select “What’s here?” option.
This will reveal the exact latitude and longitude coordinates of the cursor position on the map.
The following picture will show you how it works, the restricted area is defined by the two coordinate you set.
Copy the latitude and longitude coordinates as they appear into the first half of your Geo-fence command.
stockade123456 -34.922112, 138.587036;latitude2, longitude2“
Now place the cursor on the bottom right position of the Geo-fence, “right click”, select “What’s here?” and copy the coordinates into the last half of your command.
stockade123456 -34.922112, 138.587036;-34.934919 138.612270
With this coordinates set in the Geo-fence command, a rectangle will be created as the boundry of the Geo-frence.
no further North than -34.922112, South than -34.934919, East than 138.612270 and West than 138.587036
To cancel the Geo-fence, send command “
7. Movement alert
When movement alert is enable, once a movement of the target is detected ( a movement of 200 meter by default), the tracker will send a report to you, and the movement alert will be disable automatically.
To set a movement alert, send command “
move+password“, to deactivate the alert, send command “
8. Overspeed Alert
This is a very useful function to monitor if the target is overspeed.
To set the overspeed alert, send command “speed+password speed”.
Example: If you need to set the speed limit to 80 km/hr then send command
“speed123456 080”, the speed must be in 3 digits length, and the speed unit is km/hr.
Note: This is a one time alert, the alert will be deactivate once a speed breach is detected.
To cancel the alert, send command “nospeed+password”
