o During the debugging process, the device requires an external display screen to assist in n ) C adjusting the camera angle and device’s online parameters. The device supports signal h e output: CVBS. en z 3.4 Camera Connection
(Sh Connect channel 1 to 4 audio and video cameras. i t al ADAS / DMS Function: This function has an alarm function for fatigue driving, lane i g departure and other non-standard driving. When the driver is yawning, closing his eyes, D smoking, playing with mobile phones, making phone calls and other non-standard driving, this t t aX function will alarm through voice and upload the alarm information. M e 3.5 ADAS / DMS Installation and Debugging
3.5.1 ADAS Installation 1) Installation Position: Take the center of the windshield as the axis, move up and down
according to different vehicle types, and generally install at the lower point (Note: Do not affect the use of the wiper).
2) Installation Method: There is a circle of 3M tape on the camera, which can be directly pasted on the glass after tearing off the protective film;
3) The ADAS camera is installed in the center of the windshield and fixed with 3M tape (if the windshield is very inclined, it is installed in the position a little above the center. If it is a
10 / 14

MettaX Digital (Shenzhen) Co., Ltd.
vertical windshield, it should be installed at the position a little below the center. 4) The ADAS camera is an analog camera, which does not support hot swap. You need to
connect the cable before powering on the main device. If the main device already powered, then connect it to the ADAS camera, whether it is power supply or data line power supply, then the ADAS camera will not work normally, and the display screen can not see the ADAS image. At this time, you need to restart the main device to return to normal. 3.5.2 DMS Installation
A. Installation Position: A-pillar of the cab 1) Installation Height Requirements: 10-15cm below the horizontal line of driver’s eyes
TD (the camera should have a slightly inclined upward angle to look up at the driver’s eyes, which ., L is better for fatigue detection).
Co 2) Installation Distance Requirements: Within the range of 70cm-100cm from the driver’s n ) head.
zh e 3) Installation Method: Drill the base of the gimbals and fix it on the A-pillar, use screws to en fix the lens on the gimbals, adjust the angle to the display screen and fix the lens with the (Sh inner hexagon (the gimbals can be adjusted up, down, left, and right, and the installation will it al be more convenient).
i g 4) Installation Angle Requirements: Adjust the camera angle through the video to make D the driver’s face up and down in the middle of the entire video.
t t aX B. Installation Position: Car Dashboard M e1) Installation Angle: Ensure the camera is within 30 degrees to the right of the driver’s
direct line of sight. The smaller the angle, the better. 2) Installation Distance: The distance between the camera and the driver’s face should be
within the range of 60 cm to 120 cm. It is recommended to install the camera at approximately 80 cm from the driver’s face.
3) Other Requirements: Ensure the DMS camera does not obstruct the driver’s view or interfere with their operations. Ensure there are no obstructions such as the steering wheel between the DMS camera
11 / 14

MettaX Digital (Shenzhen) Co., Ltd.
and the driver’s face. The DMS camera must remain level horizontally and should not be tilted. While meeting the above conditions, the angle deviation from the driver’s face should be
minimized. Ideally, the camera should face the driver directly.
3.6 Power Connection

1. Connect the power to the device according to the definition of power line interface. Before connecting, please check the connected power supply voltage, which should be in the range of 9V – 36V, The recommended operating voltage is 12V or 24V to prevent the
   D equipment from abnormal due to voltage mismatch. LT 2) The red line (positive pole) of the power supply is connected to the positive pole of the
   o ., vehicle main control power supply. The black (negative) of the power supply should be ) C connected to the negative pole or ground of the vehicle power supply. When grounding, it is en necessary to ensure the good conductivity of the ground.The power supply (ignition) shall be zh connected to the ignition control cable, which has power only when the vehicle is h en running.Please connect the red line and the orange line together to the positive pole of the (S power supply when debugging the product with the power adapter. it al 3.7 Product Installation Place Requirements
   Di g The device can be embedded into the dashboard of the car through the sleeve, and it can X also be fixed. Please pay attention to the following points during installation:
   t t a 1) Waterproof: You should choose a location that is not suitable for water to ensure that M e the terminal is dry, and pay attention to keeping away from the air outlet of the air conditioner
   to prevent condensation from accumulating inside the terminal when the temperature difference changes.
2. Earthquake Proof: the terminal cannot be suspended and installed in a position with large long-term vibration.
3. Anti Interference: The terminal should be kept away from single equipment such as audio-visual and intercom in the car to prevent conduction and radiation interference.
