Signal Detection and Control
8 signal inputs, 1 output, 5V power control.

Alarm
Emergency alarm, parking timeout alarm, overspeed alarm, overspeed warning, fatigue driving alarm, deviating line alarm, power loss, low power alarm, GPS fault alarm, GPS/4G antenna open short circuit alarm, etc.

Drive recorder
The terminal has the vehicle driving record function, continuously records and stores the vehicle driving status data at a time interval of 1s, the driving data includes: the real-time time of the vehicle during driving, the corresponding average speed in the interval of each second and the status signal of the corresponding time, and the effective data record is not less than the last 48 hours. The speed recording unit is kilometers per hour (km/h), and the measurement range is 0km/h~220km/h.

Vehicle Driving Analysis
A function that supports analysis of driving behavior (sharp acceleration, sharp deceleration, idle, hard braking, etc.) using body data (CAN, analog signal data, etc.).

Cloud Guardian
It supports remote “cloud” guardian functions such as remote fault diagnosis and debugging, remote automatic program maintenance, remote parameter configuration and terminal operation statistics. Improve equipment installation and maintenance efficiency, save maintenance time and costs.
