The LW4G-12G is a 12-wire CAT1 4G anti-jammer GPS tracker, which can perform functions such as engine shutdown, two-way communication (Mic+Speaker), remote fuel/electricity cut-off, SOS alarm, analysis and reporting of driving behavior data, collision alarm, etc. The device has a 3-way data load to the platform. It can meet the monitoring needs of commercial enterprise vehicles, online car monitoring, car rental service, car rental, logistics cargo transportation, and other related scenarios. In addition, the device integrates a 1-channel analog AIN input, which can load data such as fuel volume, temperature, pressure, cargo weight, etc. The device also has a 1-wire interface that can be linked with an I-Button for driver identification, vehicle anti-theft hardware, and other functions. The RS485/RS232 interface of the device can be adapted to all those interface sensors through debugging.

Weight: 49.5g
Positioning Methods: GPS/LBS
Certification: CE
Product Introduction
Positioning: Upload positioning information, such as longitude and latitude.
Information Upload: According to the interval configuration.
Power On/Off State: Each data packet uploaded contains the power-on state.
External Power Cut-off Alarm: When the GPS tracker detects that the external power source is disconnected, the device will report a power cut-off alarm (turn on the backup battery).
Low Power Alarm/Low Battery Alarm: When the GPS tracker detects that the external power is too low, it will report a low power alarm.
Remote Oil/Circuit Cut-off: Send remote commands to remotely turn on/off oil/circuit (relay required).
Shock Alarm: Upload the shock alarm when a car accident occurs (built-in acceleration sensor).
Driver Behavior Alarm: Harsh acceleration, harsh braking,
sharp turns (built-in acceleration sensor).
Trailer Alarm: When the ignition is off, the trailer alarm will be uploaded if the front of the vehicle is lifted, and movement occurs.
Geofences: Send geofence data through the platform, generate a geofence alarm when the vehicle enters or exits the area. Supports 10 hardware geofences.
Vibration Alarm: When the ignition is off, if there is vibration, the alarm information is uploaded.
Speeding Alarm: Upload alarm information when the speed exceeds the set value.
Message Buffer: Positioning data will be stored in the buffer when in network blind spots, and the data will be uploaded later when the tracker connects to the network. Buffer Memory: 5000
Power Saving Mode: Switches to standby mode when the vehicle is stationary.
OTA: Compatible with OTA.
Custom Protocol: Compatible with multiple custom protocols.
