2. Power Connection
Connect the camera to a stable 12 Volts DC power source. Ensure that the power connection is secure and properly insulated to prevent short circuits or power interruptions. It is often recommended to connect the camera's power to the RV's reverse light circuit so it activates automatically when reversing.

This camera is exclusively compatible with the 2025 version of the S21 Monitor. For pairing instructions, please refer to the specific user manual provided with your S21 Monitor. Generally, the process involves powering on both the camera and the monitor, then initiating a pairing sequence on the monitor to establish a wireless connection.
Operating Instructions
1. Basic Operation
Once the camera is installed, powered, and successfully paired with your S21 Monitor, the live video feed should automatically display on the monitor when the RV is in reverse or when the camera system is manually activated. Consult your S21 Monitor's manual for detailed information on display settings, viewing modes, and controls.
2. Night Vision
The camera is equipped with integrated night vision technology. This feature automatically activates in low-light conditions, providing a clear and enhanced view to assist with maneuvering in the dark.
Maintenance
- Cleaning the Lens: Regularly clean the camera lens with a soft, damp cloth to remove dirt, dust, or water spots. Avoid using abrasive cleaners or harsh chemicals that could scratch the lens.
- Cable and Connection Inspection: Periodically inspect all power cables and connections for any signs of wear, fraying, or corrosion. Ensure all connections remain secure.
- Mounting Security: Check that the camera remains securely mounted to your RV. Tighten any loose screws or mounting hardware as needed.
