4321 GPS OFF

GPS Sniper activation:
 

4321 GPS ON

Note: 

In the case of current shutdown of

„Monitor“ protection and „GPS“ protection (GPS OFF), 
the system automatically turns off also the GPS receiver and therefore the „SPEED“ 
protection can not be used too.

1. PROTECTION 

 

GPS Sniper possible to use for the protection of the vehicle as an autono-

mous device, or together with the existing alarm. If you are using localizer absolutely, 
you could use the “GPS ON” mode and “Monitor” mode. If you use it with the external 
car alarm, then you have additionally available “INPUT Alarm” mode.  

WAYS OF PROTECTION:
- 1.1 

Motion detected by GPS unit

- 1.2 

Turning the ignition ON in “Monitor” protection

- 1.3 

Input 2 control– if it is enabled

- 1.4 

JAMM protection (detection of GSM signal jamming) – if it is enabled

- 1.5 

Car battery discharge protection

- 1.6 

Speeding– if it is set

- 1.7 

Tilt sensor protection – if it is enabled

1.1 „GPS ON“ Mode

 

GPS triggers alarm, if the vehicle is set in motion and the ignition is turned 

OFF. It is the protection against towing the car. This type of protection is recommended 
to have turned ON permanently. It is not necessary to deactivate before driving. If you 
start the car, GPS protection is interrupted automatically by itself throughout the drive. 
Activating the function by SMS command „4321 GPS ON“.

Activation:

 

                    GPS protection is activated and deactivated by ignition, it is deactivated by 
starting the car, activated with the ignition turned OFF. GPS alarm is trigerred when the 
vehicle is set to move and the ignition is turned OFF (pulling off).

Response to GPS alarm:

 

              
During the active period of GPS alarm (alarm 
triggered) the alarm SMS are sent also with 
the GPS location. The total number of SMS sent 
depends on the actual configuration set. 
You can cancell the GPS alarm, if you send 
SMS command: „4321 GPS OFF“.

1.2 „MONITOR“ Mode

 

The mode is identical to the GPS ON mode, but does not consider the actu-

al ignition status. GPS alarm is triggered allways, if the car is set into move, no matter if 
ignition ON or OFF.  

Activation:

 

It is activated by dialing GPS Sniper telephone number from an authorized 

phone number (GPS Sniper rings 2x then reject the call).   

Deactivation:

 

It is deactivated by dialing the GPS Sniper phone number from an authori-

zed phone number (deactivation is confirmed by rejecting the call from the GPS Sniper 
side). The deactivation must be carried out before each drive. (the call is rejected from 
the GPS Sniper side immediately). 

GPS alarm triggering:

 

 

GPS alarm is triggered whenever the car is set to move (if the mode active).

Response to GPS alarm:

 

The device will send the alarm SMS immediately in the form „ALARM, IGNI-

TION IS ON“, if the ignition is ON by the „Monitor“ mode active. The alarm SMS also 
includes GPS coordinates and a link to „maps.google.com“. The alarm SMS are sent re-
peatedly with the GPS location information throughout the period of GPS alarm is acti-
ve. Total number of alarm SMS sent depends on actual configuration set. You can can-
cell the GPS alarm by dialling the GPS Sniper phone number from any of the authori-
zed phone numbers. The cancellation is confirmed by immediate rejection of the call.

1.3 Input 2 control protection

 

You  could  utilize  the  Input  protection,  only  if  there  is  oem  or  aftermarket 

alarm already installed in the car. The output of the original alarm is connected then to 
input contact of GPS Sniper. The device will send SMS message to authorized phone 
number, if the signal occurs on the input of GPS Sniper.
