Usually people enter the Alert Status after 1 minute normal driving, but some people who wear
glasses need take at most 5 minutes. If you are in real sleep after the system enters to the Alert

movements or long talking, without any fatigue condition, it only gives you one or two friendly

After the product is connected to power supply for 2 seconds, the green light will flash for 1 second.
If it is at night, the infrared light will get red. In the first 30 seconds, the system detect the driver’s
position and analyzes driver’s condition, it does not make warnings during this period. Only after
the driver has been keeping driving for more than 30 seconds, the system will enter into alert status.
However, once power is on, the system will detect if the driver’s eyes are open or not. If the green
light is on, it means the driver’s eyes are open. If the green light is off, it means the driver closes
eyes or driver is not in the detecting range of the camera. For the first time installation, you can
adjust the camera’s position based on the green light’s display.

People Image Identification
For special populations, such as people with thin eyebrows or with no eyebrows, the system need
1-60 seconds to detect, if the green light turns on when open eyes and green light turns off when
close eyes, it means the identification is successful.
The product may not be able to identify some old age people (above 60 years old and young age
people (below 15 years old, also can’t identify people who have only one eye (the system is
designed based on two eyes. Old people can be detected if they are in good body condition, big
scar around the eyes cannot be identified as well.
For some rare people, if can’t be identified by the system after 1 minute, we suggest not use this
product. If they still hope to buy it, they can provide the front face photos to us. We can make
special one for them, but need additional cost and time.
Wear Glasses or Sunglasses or Contact lens
For drivers who wear glasses or sunglasses or Contact lens, the system can also detect. If they wear
the glasses with frame, in case the frame ward off driver’s eyes, better to put the glasses a little bit
more up on the nose, or install the host more lower (the position is lower if installing inside the dash
board, we suggest to wear the glasses without frame.
For people who wear deep color sunglasses, they can install the host closer, we suggest wear bigger
sunglasses.
For contact lens, without any affection.
