7. Troubleshooting

7.1. No Signal, Black Screen, or No Picture

• Signal Format: Ensure your monitor or Android unit is set to the correct signal format (AHD). This camera requires an AHD-compatible display.
• Connections: Verify that the red trigger line is correctly connected to both your vehicle's reverse light power and the monitor's reverse-in cable. Check all video and power cable connections for looseness or damage.

7.2. Black and White Screen / No Color

• Camera System: Incorrect camera system selection (e.g., PAL/NTSC mismatch) can cause a black and white display. The AHD1080P camera typically uses the PAL system. Select the correct system on your monitor and restart the camera power.
• Video Cable: Inspect the 6-meter video cable for any damage. Try replacing it with another known good 6M cable to test if the issue persists.

8. User Tips

• Always ensure your display unit is AHD-compatible for optimal performance. If your unit does not support AHD, the camera will not function correctly.
• The camera is primarily designed as a reversing backup camera to assist with parking and maneuvering.
• For any issues during installation or operation, refer to the troubleshooting section or contact customer support.
