4. Adjust the left and right angle joints of the DMS camera through the hexagon
socket screws, so as to adjust the angle of the DMS camera left and right.
5. After adjusting the angle of the DMS camera up and down/left and right, make
sure that the driver sits according to normal driving habits and posture, to meet
the following conditions:
(1) Make sure that the driver's face appears in the middle of the video screen,
and the lower edge of the screen is below the driver's chest.
(2) Make sure that the fill light of the DMS camera faces toward the driver's
face (the fill light shall not face toward the seat belt; otherwise, it will lead
to overexposure of video).
