J16 GPS Tracker is a popular and ANATEL approved live tracking device with engine kill function. Its GSM module is SIM7670SA module which supports bands of all countries and work in all countries, especially for USA, Brazil, Mexico, Chile, Peru, Ecuador, Columbia, Argentina, etc.

ANATEL certification is a must to sell and distribute the J16 GPS tracker in Brazil. It is small in size and comes with built in antenna. By connecting with relay, it can remotely cut off vehicle engine. As well, it has a built-in 150mAh backup battery. In case of tamper or disconnection with main power, there is alert at APP or preset phone number.

J16 GPS tracker has 2 versions because of the quantity of wires

4 wire: It is a basic GPS tracker with engine immobilize by connecting with a 12V or 24V relay.

8 wire: Beside engine kill function, SOS button for emergency alert and Microphone for remote voice monitoring are included.

The latest J16 GPS Tracker supports anti-jammer. When signal jammer is detected, J16 shall automatically cut off vehicle engine so as to avoid vehicle theft. 12V or 24V relay should be connected to realize Engine Cut feature.

J16 LTE GPS Tracker Anti-Jammer

Jammer devices are electronic gadgets designed to disrupt or block wireless communication signals. They work by emitting radio frequency interference, which interferes with the normal functioning of various wireless technologies such as GSM (Global System for Mobile Communications), LTE (Long-Term Evolution), and GPS (Global Positioning System). They are used by thieves or hijackers to steal or rob vehicles.

However, with J16 Anti-jammer function, if any jammer signal is detected, the device can control relay to cut off engine, so as to avoid vehicle theft.

You can find below about how to setup and activate anti-jammer function.

J16 Bluetooth GPS Tracker with Bluetooth Relay

In the current GPS tracker markets, a wired relay are used to cut off engine in case of emergency or vehicle theft. However, it is easy to be removed since GPS tracker installation places are easy to be found by following wires, so are the wired relays. To enhance vehicle security and anti-theft function, we developed the bluetooth J16 GPS tracker and bluetooth Relay. The bluetooth relay can be installed hiddenly to avoid fast ad easy dismantle. A GPS tracker can max connect with 3 bluetooth relays. If GPS tracker is removed and put out of range of the bluetooth relay connection, the bluetooth relay shall automatically cut off engine in 10 minutes.
