The description of Real time GPS Tracker TK121

The TK121 has the feature that remote vehicle disabling systems with cut engine, cut oil.TK121 is a GPS Tracker that installs behind the dashboard. 

To know more about the features of remotely shut off engine for car

The tracker updates times could setup by you and can be installed almost all round the vehicle. The TK121gps tracking remote vehicle disabling systems is used to remotely disable the ignition from any location using your phone or computer. 

The Hard Wire Tracker will provide up to a one year report history of all events including the miles per hour, ignition on/off, motion detected and stopped, as well as several other events. GPS tracker TK121 is a tracking device which is based on GSM /GPRS network and GPS satellite positioning system.

It can be set multiple functions of positioning, tracking, monitoring, alarms etc. Eelink GPS tracker is based on GSM/GPRS network and GPS global positioning system for precise position of vehicle,valuables,children, assets.Each GPS tracker need to install smart SIM card. 

The SIM card receive signals from satellites per 30 seconds( Timer could be set) and transmit signals by GSM/GPRS network to our server. User could view the real time location and historical route of vehicle on google map by web browser/ mobile android /iOS APP, SMS.
