7. Why the device don’t alarm when I closed my eyes?
It have 3 reasons:
First, the device need to recognize the driver’s face in the first 10-20 seconds after powered on, it can’t be triggered in this period.
Second, the device is smart, if you have big body movement, or speaking, or turned you head, it will recognize that you are in sober status and wouldn’t give our alarms until 5-7 seconds.
Third, you are too near, far, low or high, means you are not in center of the camera’s shot area, please adjust your seat and the direction ball.
On the other hand, if you have no movement, speaking, driving in a high speak, and your eyelid is lower and lower, it will give out alarms in 2 seconds as long as your eye closed or pupil can’t be detected.
