2. Setup and Installation
Proper installation is crucial for optimal performance of your PixelMan PMG3A Backup Camera. Please follow these steps carefully.
2.1 Package Contents
Before beginning installation, ensure all components are present:
- PixelMan PMG3A Backup Camera
- Power Adapter Cable
- RCA Video Cable (approximately 26.3 ft / 8 meters)
- Angle Adjustment Gaskets
- Mounting Hardware (screws, double-sided tape, cable ties)
- Instruction Manual
2.2 Mounting the Camera
The PMG3A features a mini round design for discreet installation. A small hole (diameter 6mm) is required for mounting the camera's threaded rod.
- Choose a suitable mounting location on your vehicle, typically near the license plate or on the rear bumper, ensuring a clear view. The recommended installation area is 1.3 x 1.4 inches.
- Drill a 6mm diameter hole at the chosen location.
- Insert the camera's threaded rod through the hole.
- Use the provided angle adjustment gaskets and double-sided tape to secure the camera and set the desired viewing angle. Gaskets are included to adjust the camera's view angle downwards or upwards.
- Fasten the screw from the inside to secure the camera firmly to the car mounting surface.

2.3 Wiring Connections
The camera uses a 4Pin-to-RCA connector system. The total length of the cable from the camera to the connector is approximately 30.8 ft (9.4 meters), utilizing double-shielded cable for stable signal transmission.
- Connect the camera's power adapter cable to the vehicle's reversing lamp (12V+ for positive, GND- for negative). Ensure the trigger wire is connected properly.
- Connect the RCA video cable from the camera to your car's display unit, ensuring your display has an RCA input. If your vehicle's screen does not have an RCA input, a separate RCA adapter converter may be required.
- Route all cables carefully, avoiding over-pulling or bending, which can affect stability and performance. Use cable ties to secure wiring.

4.2 Cleaning
To maintain clear image quality, periodically clean the camera lens with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the lens or housing.
5. Troubleshooting
If you encounter issues with your PixelMan PMG3A Backup Camera, refer to the following common problems and solutions:
- Black Screen, Streaks, or Flashing: If the screen displays a black image, streaks, or flashes, it may indicate an unstable current from the reversing lamp. A 12V DC power adapter filter rectifier is required to stabilize the power supply.
- No Signal:
- Check all cable connections, ensuring they are secure and correctly plugged into the RCA input of your display unit and the vehicle's power source.
- Verify that the camera is receiving power when the vehicle is in reverse.
- Confirm your display unit is set to the correct video input channel.
- Image Upside Down or Mirrored: If the image orientation is incorrect, check if your display unit has settings to flip or mirror the image. Some cameras have a wire loop (e.g., green wire) that can be cut to change the display mode; consult your specific wiring diagram. Note that some users have reported issues with this feature.
- Poor Image Quality (Blurry, Dark, or Distorted):
- Ensure the camera lens is clean and free from dirt or obstructions.
- Verify that the camera is securely mounted and not vibrating.
- Check the display unit's settings for brightness, contrast, and color.
- Confirm that the camera is compatible with your display's resolution. The maximum output pixel of the camera is 1920 x 1080p, but the display effect is related to the screen resolution.
- Cable Length Issues: If the included cable is too short for your vehicle, an extension cable may be necessary. Ensure any extension cables are compatible with the camera's 4-pin or RCA connectors.
