Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Jansite AHD&CVBS 2-in-1 Backup Camera. This camera is designed to enhance vehicle safety by providing clear rear-view imaging, supporting both AHD (Analog High Definition) and CVBS (Composite Video Broadcast Signal) video formats, and featuring enhanced night vision capabilities.
Product Features
AHD and CVBS Signal Options
The camera supports both AHD and CVBS video signal outputs, allowing compatibility with a wide range of monitors. AHD provides a significantly clearer image compared to traditional CVBS, especially in low-light conditions.

Adjustable Viewing Modes
The camera offers customizable settings for parking guidelines, video signal type, and image orientation. These settings are adjusted by cutting specific wire loops on the camera's cable. Always power off the camera before cutting any wire loops and power on again afterward for changes to take effect.

Optimal 140-Degree Wide Angle Lens
The camera features a 140-degree wide-angle lens, providing a balanced field of view that reduces blind spots without significant distortion. This angle is recommended for accurate and useful reversing assistance.

Enhanced Night Vision and Image Quality
Equipped with advanced optical sensor technology, the camera automatically adjusts to various lighting conditions, providing clear images in bright light, underground parking, and low-light night environments.

Setup and Installation
Wiring Diagram
Follow the diagram below for proper connection of the backup camera system. This camera is suitable for both rear and front view applications, but the head unit is not included.
Image: Detailed wiring diagram showing connections to the car radio, camera power source, and reversing lamp.
- Connect to Car Radio: Connect the RCA video cable from the camera to the video input of your car radio/monitor.
- Camera Power Source: Connect the camera's red wire to the positive (+) terminal of your vehicle's reversing lamp. Connect the black wire to a ground (-) point.
- Trigger Wire (Optional): If your head unit requires a trigger signal for reverse, connect the trigger wire (usually a thin red wire integrated with the RCA cable) from the camera's power line to the head unit's reverse trigger input.
Component Overview
Ensure all components are present before beginning installation.

Operating Instructions
The camera's functionality can be customized by cutting specific wire loops. Always ensure the camera is powered off before making any changes and then power it back on.
Image: Visual guide for cutting wire loops to adjust camera settings.
- Parking Guideline Control:
- To keep the parking guidelines visible: Do not cut the green wire loop.
- To remove the parking guidelines: Cut the green wire loop. - Video Signal Output Switching:
- For CVBS video signal output (default): Do not cut the orange wire loop.
- For AHD video signal output: Cut the orange wire loop. - Image Orientation Adjustment:
- For mirror image (rear view, default): Do not cut the white wire loop.
- For positive image (front view): Cut the white wire loop.
Maintenance
Regular maintenance ensures optimal performance and longevity of your backup camera.
- Clean the Lens: Periodically clean the camera lens with a soft, damp cloth to remove dirt, dust, or water spots that may obstruct the view. Avoid abrasive cleaners.
- Check Connections: Inspect all cable connections regularly to ensure they are secure and free from corrosion or damage. Loose connections can lead to signal loss or flickering images.
- Inspect Mounting: Verify that the camera is securely mounted and has not shifted, which could alter the viewing angle.
- Wiring Integrity: Ensure that the wiring is not pinched, frayed, or exposed to excessive heat or moisture.
Troubleshooting
If you encounter issues with your backup camera, refer to the following table for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on monitor | Loose power or video connection; Incorrect video input selected on monitor; Camera not receiving power. | Check all cable connections; Ensure monitor is set to the correct video input (e.g., AV1, AV2); Verify power supply to the camera. |
| Flickering or distorted image | Poor connection; Electrical interference; Damaged cable. | Secure all connections; Ensure cables are not near high-voltage wires; Replace damaged cables if necessary. |
| Image is reversed or upside down | Incorrect image orientation setting (white wire loop). | Power off the camera, cut or keep the white wire loop as desired, then power on. |
| Parking guidelines not appearing | Guidelines disabled (green wire loop cut). | Power off the camera, ensure the green wire loop is intact (not cut), then power on. |
| Image quality is poor (not AHD) | Camera is in CVBS mode; Monitor does not support AHD. | Power off the camera, cut the orange wire loop for AHD output, then power on. Ensure your monitor is AHD compatible. |
