4. Installation Guide
The Sinjet H6 dash cam is designed for universal vehicle fitment with an assembly installation method. It features a separated rear camera for flexible placement.
4.1 Mounting the Main Unit
- Carefully remove your vehicle's existing rearview mirror.
- Attach the provided bracket to the main rearview mirror dash cam unit.
- Mount the main unit with the bracket onto your vehicle's windshield, ensuring a clear view for the front camera and easy access to the screen.
- Adjust the angle of the main unit to capture the desired front view.

4.2 Installing the Rear Camera
- Identify a suitable location for the rear camera, typically above the license plate or inside the rear window, ensuring a clear view of the road behind.
- Securely mount the rear camera using appropriate fasteners (not explicitly shown but implied by 'assembly').
- Route the rear camera cable from the rear of the vehicle to the main dash cam unit, ensuring it is tucked away safely and does not interfere with vehicle operation.
- Connect the rear camera cable to the designated port on the main unit.

4.3 Power Connection
- Connect the power harness to the main unit.
- Route the power harness to your vehicle's power source (e.g., fuse box for hardwiring, or cigarette lighter adapter if provided). Ensure the connection is stable and provides 9V-16V.
- Conceal the power cable along the vehicle's interior trim for a neat and safe installation.
4.4 Inserting the TF Memory Card
- Ensure the dash cam is powered off.
- Insert a high-speed TF memory card (4G-128G, Class 10 or higher recommended) into the designated slot on the main unit.
- Gently push until it clicks into place.
Important: Format the TF card within the dash cam's settings before first use and periodically thereafter to ensure optimal performance and prevent recording errors.
4.5 Camera Angle Adjustment
After installation, power on the device and adjust the front and rear camera angles to ensure they capture the desired field of view. The front camera has a 108° horizontal angle, and the rear camera has a 95° horizontal angle.

5. Operation
5.1 Power On/Off
The dash cam will automatically power on and begin recording when your vehicle's ignition is turned on. It will power off automatically when the ignition is turned off.
5.2 Recording Modes
- Continuous Loop Recording: The device continuously records video in short segments. When the memory card is full, it automatically overwrites the oldest unlocked footage.
- Dual Recording: The dash cam supports simultaneous recording from both the front and rear cameras.
- Crash Detect and Record (G-sensor): The built-in three-axis stereo crash acceleration sensor detects sudden impacts or collisions. In such events, the current video segment is automatically locked and saved to prevent overwriting, serving as crucial accident evidence.
- Time-lapse Video: This feature allows for extended recording periods by capturing frames at a lower rate, useful for parking surveillance.
5.3 Screen and Display
The 9.35-inch IPS touch screen provides a clear and responsive interface.
- Full Screen Touch: Slide your finger to the left or right on the screen to switch the display between front view, rear view, and dual view (both cameras displayed simultaneously).
- Auto Light-sensing: The screen brightness automatically adjusts according to the ambient light conditions for optimal visibility.
- Low-light Level Night Vision: The cameras are equipped with advanced technology to provide clear video recording even in low-light conditions at night.
- HLC (Highlight Compensation): This feature helps to reduce glare from bright lights (e.g., headlights) in the recording, improving clarity.


5.4 Wi-Fi Connectivity and App
The Sinjet H6 supports Wi-Fi connectivity, allowing you to connect your smartphone via a dedicated app.
- Connect to Wi-Fi: Access the Wi-Fi settings on your dash cam and smartphone to establish a connection.
- App Functionality: Through the mobile app, you can view live footage, browse recorded videos, download clips to your phone, and share them on social media platforms.

6. Maintenance
- Cleaning the Lens: Use a soft, lint-free cloth to gently wipe the camera lenses. Avoid abrasive materials or harsh chemicals that could scratch the lens.
- Cleaning the Screen: Use a microfiber cloth to clean the touch screen. If necessary, slightly dampen the cloth with water or a screen-safe cleaner.
- TF Card Management: Periodically format the TF card (at least once a month) through the dash cam's settings to maintain optimal recording performance and prevent data corruption. Replace the TF card if you notice frequent errors or reduced performance.
- Firmware Updates: Check the official Sinjet website or contact customer support for any available firmware updates to ensure your device has the latest features and bug fixes.
