What is the use of SMS location analysis function?

1. Timing positioning: the device can report the current location information of the device at regular intervals according to the time preset by the user.

2. Overspeed alarm: When the vehicle speed exceeds the preset speed, an alarm sound will be given.

3. Network query: By accessing the "Eye of the Sky" system, you can track the current state of the vehicle and track the playback within a set time period.

4. Power supply monitoring: the vehicle power supply is the main power supply, and the standby lithium battery is the auxiliary power supply. When the main power supply is cut off, the SMS will remind the user that the standby power supply will start automatically.

5. One-button alarm: In case of emergency, press and hold the emergency alarm button for 3 seconds, and the device will automatically send a short message and call the authorized preset number for help.
