4. Setup and Installation
Proper installation is crucial for the optimal performance of your backup camera system. Follow these steps carefully:
4.1 Camera Installation
- Mounting: The camera is typically mounted using the provided license plate bracket. Secure the camera to the top or bottom of your vehicle's license plate using the existing license plate screws or the included screws. Ensure the camera has a clear, unobstructed view. An alternative butterfly bracket is provided for other mounting options if preferred.
- Wiring: Connect the camera's red power wire to a 12V DC power source. For automatic activation when reversing, connect it to your vehicle's reverse light power wire. For continuous use, connect it to a constant 12V source (e.g., fuse box or cigarette lighter/power point/ignition switch). Connect the camera's black wire to a reliable ground point on the vehicle chassis.

4.2 Monitor Installation
- Mounting: Attach the 4.3-inch LCD monitor to your dashboard or windshield using the magnetic suction cup bracket. Adjust the bracket to achieve the desired viewing angle. The magnetic bracket allows for 360-degree rotation.
- Wiring: Connect the monitor's power cord to a 12V DC power source in your vehicle (e.g., cigarette lighter socket or fuse box). Connect the monitor's black wire to ground.
4.3 Connecting Camera to Monitor
Use the provided AV signal line (video cable) to connect the video output from the camera to the video input (AV1 or AV2) on the monitor. Ensure all connections are secure.

5. Operating Instructions
Once installed, operating the Yuwei Backup Camera System is straightforward:
- Automatic Activation (Reverse Gear): If the camera is wired to your vehicle's reverse lights, the monitor will automatically display the camera feed when you shift into reverse gear.
- Continuous Use: If the camera is wired to a constant 12V power source, the monitor can be turned on manually to display the camera feed at any time.
- Monitor Adjustment: Use the magnetic bracket to adjust the monitor's position and angle for optimal viewing while driving.
6. Maintenance
To ensure the longevity and clear performance of your Yuwei Backup Camera System, follow these maintenance tips:
- Clean the Camera Lens: Regularly wipe the camera lens with a soft, damp cloth to remove dirt, dust, or water spots that may obstruct the view. Avoid abrasive cleaners.
- Clean the Monitor Screen: Use a soft, lint-free cloth to clean the monitor screen. For stubborn smudges, a screen cleaner designed for electronics can be used.
- Check Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Avoid Extreme Temperatures: While the system is designed for temperature resistance, prolonged exposure to extreme heat or cold when not in use may affect performance.

If you encounter issues with your Yuwei Backup Camera System, refer to the following troubleshooting guide:
- No Image on Monitor:
- Ensure all power connections to both the camera and monitor are secure and receiving 12V DC power.
- Check the video cable connection between the camera and monitor. Ensure it is fully inserted into the correct AV input.
- Verify that the vehicle's reverse lights are functioning if the camera is wired to them.
- Distorted or Flickering Image:
- Check for loose video cable connections.
- Ensure the power supply is stable and free from interference.
- Clean the camera lens.
- Monitor Not Turning On:
- Check the monitor's power connection and ensure the vehicle's ignition is on if connected to an ignition-switched power source.
