1. Product Introduction
Thank you for purchasing our waterproof backup camera. This backup camera can be used to check the surroundings of your vehicle, eliminate blind spots, and improve driving safety.
The Jansite AHD Rear View Camera features a 360° rotatable metal body, offering a 170° wide viewing angle with a fisheye glass lens. It provides high-definition images (up to 1920x1080P) and includes starlight night vision for clear visibility even in low-light conditions. The camera is IP68 waterproof and designed for easy installation.


2. Setup and Installation
2.1 Pre-Installation Check
Before proceeding with the installation, please ensure the backup camera is working correctly by temporarily connecting it to your monitor.
2.2 Mounting the Camera
The camera can be mounted on a flat surface or your vehicle's license plate. It supports multiple installation methods including horizontal, inverted, and side mount, making it suitable for rear, front, or side view applications.

2.3 Monitor Wiring Diagram
Connect the head unit and the backup camera using the provided video cable. The power cable connects to your vehicle's reversing light for power and to ground.

2.4 Video Signal Mode Selection
The camera supports both CVBS and AHD video signal modes. The default mode varies by model:
- P31-D (AHD 720P): Default CVBS mode. To switch to AHD 720P 25fps mode, cut the orange wire.
- P31-E (AHD 1080P): Default AHD 1080P 25fps mode. To switch to CVBS mode, cut the orange wire.
Note: If your head unit does not support the currently selected video signal mode, the reverse image will not be displayed. Always check your head unit's compatibility before cutting wires.

2.5 Wire Cutting Instructions
The camera has three switchable functions controlled by cutting specific wires:
- Orange Wire: Switches between CVBS and AHD video modes (specific to P31-D or P31-E).
- White Wire: Switches between mirror image (rear view) and positive image (front view).
- Green Wire: Toggles the reverse line (parking guidelines) on or off.
Important: After cutting any color wire, you must reboot the backup camera power for changes to take effect.

2.6 Camera Angle Adjustment
The camera body supports 360° rotation and 45° up/down, left/right adjustment. After adjusting the angle, tighten the screws with the attached screwdrivers to secure the position.
3. Operating Instructions
3.1 Setting the Rear Lens on Your Monitor
Lenses with CVBS video signals are compatible with all monitors. However, AHD lenses are only compatible with AHD monitors. Ensure your monitor is set to the correct video input type (AHD 720p 25fps, AHD 1080p 25fps, etc.) to display the image correctly.


3.2 Functional Upgrades
The camera offers several advanced features:
- Super Night Vision: Enhanced visibility in low-light conditions.
- AHD Lens: Analog High Definition for clearer images.
- IP68 Waterproof: Durable and resistant to water and dust.
- Easy Installation: Designed for straightforward setup.
- Adjustment Angle: Flexible camera positioning.
- Reversing Assistance: Parking guidelines for easier maneuvering.
- 170° Wide Angle: Broad field of view.
- Fisheye Lens: Provides a wide, panoramic perspective.

4. Maintenance
Regularly clean the lens of the backup camera to prevent dust, water drops, snow, or other debris from obstructing the view. Use a soft, clean cloth and a gentle cleaning solution if necessary.
5. Troubleshooting
5.1 Image Quality Issues
- Blurry, Flickering, or Stripes: If the image on the screen is blurry, flickering, or has horizontal/vertical stripes, check if your monitor supports the current video signal mode of the backup camera. Also, ensure all wiring connections are correct and secure.
5.2 Compatibility Issues
- No Image Display: If your head unit does not support the currently selected video signal mode (CVBS or AHD), the reverse image will not be displayed. Adjust the camera's signal mode by cutting the orange wire as per instructions.
- Specialized Monitors: This is a universal backup camera for monitors with an RCA connector. If your monitor only supports specialized backup cameras (e.g., those using a 4-pin 2.5mm Jack cable), this camera may not be compatible. Consult your monitor dealer or manual for specific limitations.
- GPS Devices: If connecting to a GPS device, an additional adapter with RCA connectors may be required.
5.3 Installation Issues
- Reverse Line Offset: The backup camera is best suited to be mounted in the middle of the license plate. If mounted on the side, the reverse line may appear offset.
- No Signal: Ensure the red wire of the power cable is connected to the reversing light's positive terminal and the black wire to ground. Restart the head unit after installation.

8. User Tips
- Signal Compatibility: If you experience a 'no signal' message, especially when switching between CVBS and AHD, double-check that your head unit explicitly supports the selected signal type. Some older units might only support CVBS.
- Connector Types: Be aware that this camera uses an RCA connector. If your existing system (e.g., a rearview recorder) uses a different connector like a 4-pin 2.5mm Jack cable, you will need an appropriate adapter.
- Power Cycle After Wire Cuts: Always remember to power cycle your camera (and ideally your head unit) after cutting any of the control wires (orange, white, green) to ensure the changes are applied.
