After the tracker is properly configured, you can activate the arm mode and enable the over-speed alarm.Then, set a specific speed limit and choose how you want to receive alerts — by SMS, platform message, or phone call.The GPS module continuously monitors the moving speed of the device.It does this by using satellite signals to determine the tracker’s position in real time.Every short interval, such as one second, the system records the device’s longitude, latitude, and altitude.When several position points are collected in sequence,the tracker calculates the distance traveled over time to determine the current moving speed.If the speed stays above the preset limit for 3 to 5 seconds,the system immediately triggers an over-speed alarm and sends notifications to your platform or control center number.It’s important to note that speed detection depends on GPS signals.If the tracker is in an area with weak or no GPS coverage,the speed cannot be detected,and the over-speed alarm will not be triggered.
