4.2 Power Connection
The camera requires a 12V DC power source. It is recommended to connect the camera's power cable to the RV's reverse light circuit. This will ensure the camera powers on automatically when the vehicle is put into reverse.
- Identify the positive (+) and negative (-) wires of your RV's reverse light circuit.
- Connect the red wire of the camera's power cable to the positive (+) wire of the reverse light circuit.
- Connect the black wire of the camera's power cable to the negative (-) wire (ground) of the reverse light circuit.
- Ensure all connections are secure and properly insulated to prevent short circuits and water ingress.
4.3 Pairing with A6 Monitor
Upon receiving a new camera or if the camera loses connection, you must pair it with your AMTIFO A6 monitor. Refer to your A6 monitor's manual for specific pairing instructions. Generally, the process involves:
- Power on the A6 monitor and the H21 camera.
- Access the pairing menu on the A6 monitor.
- Initiate the pairing process on the monitor. The monitor will search for available cameras.
- Once the H21 camera is detected, confirm the pairing on the monitor. A successful pairing will display the camera's feed on the monitor.
5. Operating Instructions
Once installed and paired, operating the AMTIFO H21 camera is straightforward.
- Power On: When the RV is started and reverse gear is engaged (if wired to reverse lights), the camera and monitor will automatically power on and display the rear view.
- Viewing the Feed: The live video feed from the H21 camera will be displayed on your connected AMTIFO A6 monitor.
- Guide Lines: The A6 monitor typically provides adjustable guide lines to assist with parking and maneuvering. Refer to the A6 monitor manual for instructions on how to enable, adjust, or disable these lines.

- Cleaning 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.
- Checking Connections: Inspect all power and signal connections regularly to ensure they are secure and free from corrosion or damage.
- Casing Inspection: Although the camera is IP69 waterproof, check the casing for any signs of damage or cracks that could compromise its water resistance.
