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.11.2. I'm worry about too much noisy alarms.Don't worry, the device have 4 level sensitivities, the lowest level mainly alarm for the real sleeping, looking around need 3-4 seconds to trigger the alarm, nobody will do it so long when driving on the highway.11.3. 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. DF600 will detect the fatigue driving, giving out alarms in the instant of dozing off to wake you up.11.4. 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!11.5.Can it connection to the vehicle power supply.For professional applications such as? vehicles team etc. ,DF600 has a cable for direct connection to the vehicle power supply.11.6. Will it influent my sight? Did I need to look at it?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. ?11.7. 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 more people don't nod at all when driving sleep.? And some people used to nod when taking or singing. So 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.In the Straight, when the Lane abnormal, the driver may be have sleep too long to can not be wake up.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 the driver's reaction time is different, when driver awake and Sleepy. It shall be more alarm when driver awake, or alarm too late when driver in sleepy.Image detect will be influenced by light and raining weather. Millimeter is too huge size and low accuracy. Laser light will Hurt the other driver's eyes.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 DF600, waking up the driver in the doze off instant,? much more efficient than those products.10.8. 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.? ?transformer car alarm?Our Services?For our customers?Together with you, we achieve high standards of quality and commitment to sustainable development.?Together with you, we are travelling the path of safety and success - yesterday, today, and tomorrow.?Other Main Products: Cuttable Fuel Level Sensor, Pet GPS Tracker
