Notice

To ensure safe use and extend the service life of the equipment, consider the following factors during installation:

• After receiving the product, check packages for the device and accessories. Contact the dealer if any parts are missing.
• Comply with specifications of relevant electronic products and vehicle requirements when installing and operating.
• Installation and construction must comply with relevant national or local standards.
• Verify the connected power supply voltage is within the 9V-36V range. An operating voltage of 12V or 24V is recommended to prevent abnormalities due to voltage mismatch.
• For hard disk-type terminals, install and secure horizontally, ensuring the inclination angle does not exceed 45 degrees to maintain shock absorption and prolong hard disk lifespan.
• For optimal GPS signal reception, ensure the GPS antenna's receiving surface faces upward, free from metal objects. The antenna's bottom should be flat, with an inclination angle not exceeding 30 degrees. Positioning at the junction of the dashboard and windshield is recommended.
• The MDVR device should operate within specified temperature and humidity ranges.
• External wires should have sufficient intervals and protection (e.g., flame-retardant tube) to prevent electric leakage due to wear or aging.

1. Product Specifications

2. Appearance and Accessories

The device features an indicator panel with LEDs for PWR, GPS, REC, and NET status.

2.1. LED Indicator

• [PWR] Power input status indicator: Always on.
• [GPS] GPS indicator light: Steady light indicates successful GPS connection; flashing means no GPS signal; long off means the module is not present.
• [REC] Video light: Flashes during video recording; always on means not recording when disk exists; light off means the medium does not exist.
• [NET] Network light: Always on when the system is successfully registered with the server; blinks otherwise; long off means the module does not exist.

2.2. Definitions of External Cables

The device connects to external components via a multi-pin connector. The following table details the wire functions:

2.3. Aviation interface

The aviation interface connector provides connections for power, video inputs, network, and video output. The connections are as follows:

3. Installation Instructions

3.1. SD Card & SIM Card

To install the SD card and SIM card: Insert the SD card into the SD card slot with the connecting finger upward, and the SIM card into the SIM card slot.

3.2. Debug Screen Connection

During the debugging process, an external display screen is required to assist in adjusting the camera angle and device parameters. The device supports VGA and CVBS signal outputs.

3.3. Camera Connection

Connect channels 1 to 4 with audio and video cameras. The ADAS/DMS function provides alarms for fatigue driving, lane departure, and other non-standard driving behaviors. It will trigger voice alarms and upload information when the driver is yawning, closing eyes, smoking, using a mobile phone, or making calls.

3.4. ADAS / DMS Installation and Debugging

3.4.1. ADAS Installation

1. Installation Position: Use the center of the windshield as an axis. Adjust position up or down based on vehicle type, generally installing at the lower point. Ensure the wiper's use is not affected.
2. Installation Method: The camera has 3M tape. Tear off the protective film and paste it directly onto the glass.
3. Mounting: Install the ADAS camera in the center of the windshield and fix it with 3M tape. If the windshield is very inclined, install slightly above the center. For a vertical windshield, install slightly below the center.
4. Connection: The ADAS camera is analog and does not support hot-swapping. Connect the cable before powering on the main device. If the main device is already powered, connecting the ADAS camera (either power or data line) may prevent it from working correctly and displaying the ADAS image. Restart the main device to restore normal operation.

3.4.2. DMS Installation

A. Installation Position: A-pillar of the cab

1. Installation Height Requirements: 10-15cm below the horizontal line of the driver's eyes. A slightly upward angle is recommended for better fatigue detection.
2. Installation Distance Requirements: Within 70cm-100cm from the driver's head.
3. Installation Method: Drill the base of the gimbal and fix it on the A-pillar using screws. Adjust the angle to the display screen and fix the lens with the inner hexagon. The gimbal can be adjusted up, down, left, and right for convenience.
4. Installation Angle Requirements: Adjust the camera angle via video to position the driver's face in the middle of the entire video frame.

B. Installation Position: Car Dashboard

1. Installation Angle: Ensure the camera is within 30 degrees to the right of the driver's direct line of sight; a smaller angle is better.
2. Installation Distance: The distance between the camera and the driver's face should be 60 cm to 120 cm. Approximately 80 cm is recommended.
3. Other Requirements:
   • Ensure the DMS camera does not obstruct the driver's view or interfere with operations.
   • Ensure no obstructions (e.g., steering wheel) are between the DMS camera and the driver's face.
   • The DMS camera must remain level horizontally and not be tilted. Minimize angle deviation from the driver's face; ideally, the camera should face the driver directly.

3.5. Power Connection

1. Connect the power according to the power line interface definition. Verify the connected power supply voltage is within the 9V - 36V range. A 12V or 24V operating voltage is recommended to prevent abnormalities.
2. Connect the red line (positive pole) of the power supply to the vehicle's main control power supply positive pole. Connect the black line (negative) to the vehicle's power supply negative pole or ground, ensuring good conductivity. The power supply (ignition) should connect to the ignition control cable, which is powered only when the vehicle is running. For debugging with a power adapter, connect the red and orange lines together to the power supply's positive pole.

3.6. Product Installation Place Requirements

The device can be embedded into the dashboard or fixed. Pay attention to the following during installation:

• Waterproof: Choose a location not exposed to water to ensure the terminal remains dry. Keep away from air conditioner outlets to prevent condensation due to temperature changes.
• Earthquake Proof: The terminal should not be suspended or installed in areas prone to prolonged vibration.
• Anti Interference: Keep the terminal away from audio-visual equipment and intercom systems in the car to prevent conduction and radiation interference.
• Hard Disk Installation: The hard disk type MDVR product must be installed horizontally. The inclination angle cannot exceed 45 degrees to ensure proper shock absorption and prolong the hard disk's service life.

3.7. Product Firmware Upgrade

1. Place the upgrade software onto an SD card.
2. Insert the SD card with the upgrade file into the device.
3. Navigate to the system menu "System Information" to view the application program and MCU version numbers.
4. Ensure the upgrade version number differs from the device's current version. The device will upgrade automatically if the SD card is inserted.
5. Do not power off or operate the device during the upgrade process.
