5. Operation
5.1 Video Signal Switching
The camera outputs CVBS 30HZ/30FPS/NTSC video signal by default. To switch to AHD 1080P or AHD 720P, you must cut specific wires on the camera cable and adjust your monitor's settings accordingly.
- Cut the Green Wire: Switches to AHD-1080P-25HZ/25FPS/PAL video signal.
- Cut the White Wire: Switches to AHD-720P-25HZ/25FPS/PAL video signal.
- Cut Both Wires: Reverts to CVBS 30HZ/30FPS/NTSC video signal.
NOTE: After cutting any wire, unplug and reconnect the 4-pin power cable to apply the change. Ensure your head unit or monitor supports the selected AHD format (AHD-1080P-25HZ/25FPS/PAL or AHD-720P-25HZ/25FPS/PAL). If these options are not available in your monitor's settings, it does not support the camera's AHD features, and you should use the default CVBS signal.
Image: This diagram illustrates the process of cutting the green and white wires on the camera cable to switch between CVBS, AHD 1080P, and AHD 720P video signal formats.
Video: This video demonstrates the procedure for switching the video signal output of the GreenYi backup camera between CVBS, AHD 1080P, and AHD 720P by cutting specific wires and adjusting head unit settings.
5.2 Dynamic Trajectory Lines
The camera's integrated chip generates dynamic trajectory guidelines that move with your steering wheel. This feature helps you visualize the vehicle's path when reversing. If your head unit also provides guidelines, you may need to disable the head unit's original guidelines to avoid overlapping displays.

7. Troubleshooting
If you encounter issues with your GreenYi backup camera, please refer to the following common solutions:
- No Image Display:
- Ensure all power and video cables are securely connected.
- Verify the camera is receiving 12V DC power.
- Check if your monitor/head unit is set to the correct video input channel (e.g., AV-IN, Camera).
- Confirm the video signal format (CVBS, AHD 1080P, AHD 720P) matches both the camera's output (based on wire cuts) and your monitor's input settings.
- Flickering or Unstable Image:
- Check for loose cable connections, especially the video cable.
- Ensure the power supply is stable and free from interference.
- Verify the video signal format is correctly matched between the camera and the display.
- Overlapping Guidelines:
- If your head unit has its own parking guidelines, disable them in the head unit's settings to avoid interference with the camera's dynamic trajectory lines.
- Poor Night Vision:
- Ensure the camera lens is clean and free from dirt or obstructions.
- Verify the camera is receiving adequate power.
- Incorrect Video Format After Wire Cut:
- Remember to unplug and reconnect the 4-pin power cable after cutting any signal wire to reset the camera's output.
- Double-check your monitor's settings to ensure the correct AHD or CVBS format is selected.
