This 4G GSM and GPS tracking solution will locate and track the whereabouts of your vehicle in realtime via the Internet on a computer, Smartphone or Tablet. There are only 2 - 4 wires to connect, so installation is easy. Once you insert your 4G Sim card (not included), you hide the device away. It works by sending the vehicle's GPS coordinates via the 4G LTE network to the free online tracking service, which shows the location on Google Maps. It can also SMS longitude and latitude coordinates to up to 3 mobile phones, as well as alerts when the vehicle exits a pre-determined area or when the integrated shock sensor has been triggered. Other features include a built-in microphone to listen to what is happening in your car in realtime, and an engine kill function to remotely disable the engine. The built-in rechargeable lithium battery will keep the device functioning for up to 3 hours when power is disconnected, which could help you locate the vehicle should it have been stolen and abandoned. There is no setup or on-going tracking charges. You only pay for the GSM sim card and service.
