 FAQ

1. Is the infrared light harmful to my eyes and body?

No at all, the average light outlet power is less than 0.2W, and mostly died down when spreading in a 30°angle

and meter distance, less than 1/10 of indoor nature light, just because the infrared light can’t been seen when 

mixed with other lights, you don’t aware the existing.

2. I’m worry about too much noisy alarms.

Don’t worry, the device have have speed limit switch, if the speed less than 45km/h, the alarm never been triggered.

3. If I must drive under fatigue status, is this unit useful?

Yes, some trunk drivers always drive under fatigue status, some people used to dozy when driving in on the 

highway, or if you have sleepless night but must drive today. LS803’s main target is not to detect the fatigue 

driving, but the instant of dozing off, giving out alarms in that instant to wake you up.

4. What’s your advantage comparing to the other driver fatigue alarm system?

There are 3 kinds of fatigue alarm system on the market:

Nap zipper, it judges the fatigue status only from the driver’s nod, but some people don’t nod at all when sleeping, and some people used to nod when taking or singing, the accuracy is very low.

Lane Departure Warning system, this system have restrict, if there is no line on the road, it’s no use at all, as we know, there is too much road without any line, or only 1 line in the middle, or the line is broken, all of those will influent the accuracy.

Collision Prevention, this kind of products always use image, millimeter waves or laser light to calculate distance between your car and front/back car, but image will be influent by light and raining weather, millimeter is too expensive and huge size, laser light will kill 10,000 pieces of your retina cells if scan 30 times/second.    

And all of those products are detecting the behavior of fatigue, but some of drivers will keep driving in straight line and same speed after dozed off 10-20 seconds, it’s very dangerous if there is any overtake, obstacles or passengers. Our product LS801, waking up the driver in the doze off instant,  much more efficient than those products.

5. Is it difficult to install?

No, it’s very easy, just stick the main unit in front of the driver, and connect power from cigarette socket, no need any engineer or garage!

6. Will it influent my sight?

No, it’s much smaller than a GPS navigator, and no need you to stare at it, just leave it alone after you have adjusted the angle toward your eyes.

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.

8. Why the device not as sensitive as the beginning?

The lens is dirty, please use cotton bud to clear it, if necessary, use some alcohol.

9. It just don’t work at all, what’s the problem?

The system require 12V power and instant electric current 400-500mA, please check your power supply, if the voltage is low, or electric current is not enough, the device may have green light on, but not alarm.
