-Real time tracking :Positioning accuracy <10m in open outdoor environments
-Power cut off alarm : The device will trigger a power cut off alarm when the external
power is disconnected or the connecting cable is cut
-Fall detection alarm : After the device is installed and the device posture is identified, thedevice will report a fall detection alarm when the device posture changes.
-Tamper alarm :Report a tamper alarm when the device is removed
-Low external battery alarm : When the device detects that the external power voltage is lowerthan the set threshold, the device will trigger an low external power
battery alarm.
-Low internal battery alarm : When the device detects that the internal battery voltage is lowerthan the set threshold, the device will trigger an low internal battery
battery alarm
-Overspeed alarm : The vehicle speed threshold can be set through the platform or SMS.When the vehicle's speed exceeds the threshold within the set time,
an overspeed alarm will be reported
Vibration alarm : When the vehicle ignition is off and in a stationary state, the device
detects vehicle vibration and a vibration alarm will be reported
