Product Introduction
Dimensions: 80 (length) x 38 (width) x 17 (thickness) mm
Weight: 53g
Positioning Methods: GPS/BDS/LBS
Product Introduction
Positioning Information Upload: Uploads positioning information, such as longitude and latitude, according to the interval configuration.
Power On/Off Status: Each uploaded data packet contains the power on status.
External Power Cut Alarm: When the GPS tracker detects that the external power source is disconnected, the device will report the power cut alarm (turn on the backup battery).
Remote Oil/Circuit Cut: Sends commands remotely to turn on/off oil/circuit (relay required).
Shock Alarm: Uploads shock alarm when a car accident occurs (integrated acceleration sensor).
Driver Behavior Alarm: Harsh acceleration, harsh braking, sharp curve state upload (integrated acceleration sensor).
Vibration Alarm: When the ignition is off, if vibration occurs, it notifies with an alarm.
Speeding Alarm: Uploads alarm information when the speed exceeds the set value.
Message Buffer: Positioning data will be stored in the buffer when in blind spots of the network 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 stopped.
OTA: Compatible with OTA.
Custom Protocol: Multiple protocols supported.
