Notice
In order to ensure the safe use of the device and extend the service life of the
equipment, the user should fully consider the following factors during installation:
1) After receiving the product, please check the packages of the device and accessories
in time. If you nd any parts are missing, please contact the dealer in time.
2) When installing and operating the equipment, comply with the specifications of
relevant electronic products and the requirements of vehicles and other connected
equipment.
3) The installation and construction shall comply with the specifications, which can
refer to the relevant national or local standards.
4) Please check the connected power supply voltage, which should fall within the
range of 9-36V. To prevent equipment abnormalities due to voltage mismatch, it is
recommended to use an operating voltage of 12V or 24V.
5) The hard disk-type terminal should be installed and secured horizontally, ensuring
that the inclination angle does not exceed 45 degrees. This precaution is necessary to
avoid compromising the terminal's shock absorption capability and reducing the hard
disk's lifespan.
6) To receive best positioning signal, ensure that the receiving surface of the GPS
antenna faces upward without any metal objects above it. The antenna's bottom
should be kept flat, with an inclination angle not exceeding 30 degrees. It is
recommended to position the GPS antenna at the junction of the dashboard and
windshield for optimal performance.
7) The MDVR device should operate within the temperature and humidity range
specied by the technical indicators.
8) The external wires of the devices should have sucient intervals and the protection
of the jacket flame-retardant tube to ensure that the wires will not cause electric
leakage due to wear or aging.

To start, use the provided key to unlock and open the front panel cover. Once opened,
you will nd the interface of the SIM card, hard disk box and SD card, as illustrated in
the diagram below.
Hard Disk Installation: First, loosen the xed screws located at both ends of the hard
disk rack. Then, carefully pull out the hard disk box from the rack. After installing the
hard disk into the box, securely fasten it with screws. Next, place the box back into the
hard disk rack. Finally, tighten the xed screws to ensure the hard disk is securely held
in place.
SD card and SIM card Installation: Insert the SD card into the SD card slot with the
connecting nger upward and the SIM card into the SIM card slot. Then close the hard
disk cover and lock the hard disk on.

5.2. Antenna installation
5.3 Debug screen connection
5.4. Camera Connection
Please correctly connect the 4G and GPS antennas. To achieve optimal positioning
performance, the receiving surface of the GPS antenna must face upwards with no
metallic objects above it. The bottom of the antenna should be at, and its tilt angle
should not exceed 30 degrees. Attempt to place the positioning antenna at the junction
of the dashboard and windshield.
During the debugging process, the device requires an external display screen to assist
in adjusting the camera angle and device's online parameters. The device supports two
types of signal output: VGA and CVBS.
First connect channel 1 to 8 audio and video cameras.
DSM / ADAS function: this function has an alarm function for fatigue driving, lane
departure and other non-standard driving. When the driver is yawning, closing his eyes,
smoking, playing with mobile phones, making phone calls and other non-standard
driving, this function will alarm through voice and upload the alarm information.

5.5.ADAS/DMS Installation and debugging
5.5.1 DMS Installation
5.5.2 ADAS Installation
1) Installation position: A-pillar of the cab
2) Installation Height requirements: 10-15cm below the horizontal line of driver's eyes
(the camera should have a slightly inclined upward angle to look up at the driver's
eyes, which is better for fatigue detection).
3) Installation Distance requirements: within the range of 70cm-100cm from the
driver's head.
4) Installation method: First drill the base of the gimbal and x it on the A-pillar, use
screws to x the lens on the gimbal, adjust the angle to the display screen and x the
lens with the inner hexagon (the gimbal can be adjusted up, down, left, and right, and
the installation will be more convenient)
5) Installation Angle requirements: adjust the camera angle through the video to make
the driver's face up and down in the middle of the entire video.
1) Installation position: take the center of the windshield as the axis, move up and
down according to dierent vehicle types, and generally install at the lower point (Note:
do not aect the use of the wiper);
2) Installation method: there is a circle of 3M glue on the camera, which can be directly
pasted on the glass after tearing o the protective lm;
3) The ADAS camera is installed in the center of the windshield and xed with 3M glue (if
the windshield is very inclined, it is installed in the position a little above the center; If
it is a 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.

5.6. Power connection
5.7. Product Installation Place Requirements
1)Connect the power to the device according to the denition of power line interface.
Before connecting, please check the connected power supply voltage, which should be
in the range of 9-36V, The recommended operating voltage is 12V or 24V to prevent the
equipment from abnormal due to voltage mismatch.
2)The red line (positive pole) of the power supply is connected to the positive pole
of the vehicle main control power supply. The black (negative) of the power supply
should be connected to the negative pole or ground of the vehicle power supply. When
grounding, it is necessary to ensure the good conductivity of the ground.The power
supply (ignition) shall be connected to the ignition control cable, which has power only
when the vehicle is running.Please connect the red line and the orange line together
to the positive pole of the power supply when debugging the product with the power
adapter.
The device can be embedded into the dashboard of the car through the sleeve, and it
can also be xed. Please pay attention to the following points during installation:
1) Waterproof: You should choose a location that is not suitable for water to ensure
that 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 dierence 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.
4) The hard disk type MDVR product needs to be installed horizontally, and the
inclination angle cannot be greater than 45 degrees, so as not to affect the shock
absorption eect of the device and reduce the service life of the hard disk.

5.8. Product Firmware upgrade
1) First, put the upgrade software into SD card / U disk;
2) Insert SD card / U disk with upgrade le;
3) Enter the system menu "system information" to view the application program and
MCU version number;
4) The upgrade version number should be different from the device current version
number, and the device will be upgraded automatically if the USB ash disk or SD card
is inserted;
5) Do not power o or operate the device during the upgrade.
