3. Installation and Wiring
Proper installation and wiring are crucial for the camera's functionality. Refer to the diagrams below for specific connections. It is recommended to have this installed by a professional if you are unsure.
3.1. General Wiring Principles
- The yellow RCA connector is for video signal output.
- The red wire on the power cable is for 12V+ power.
- The black wire on the power cable is for ground (12V-).
- The 'BACK/Reverse' or 'Display Trigger Line' on your display unit (e.g., Android screen) is essential for automatic switching to the camera view.
3.2. Rear View Camera Wiring (to Android Screen)
- Connect the camera's yellow RCA video cable to the video input of your Android screen.
- Connect the red wire of the camera's power cable to the vehicle's 12V+ reverse lights power source.
- Connect the black wire of the camera's power cable to a reliable ground point (12V-).
- Connect the 'BACK/Reverse' (display trigger line) from your Android screen to the same 12V+ reverse lights power source as the camera's red wire. This ensures the screen switches to the camera view when reverse gear is engaged.
3.3. Front View Camera Wiring (to Android Screen)
- Connect the camera's yellow RCA video cable to the video input of your Android screen.
- Connect the red wire of the camera's power cable to a switched 12V+ power source (e.g., ACC power) that is active when the vehicle is on.
- Connect the black wire of the camera's power cable to a reliable ground point (12V-).
- Connect the 'BACK/Reverse' (display trigger line) from your Android screen to a suitable trigger for front camera display (e.g., a manual switch or a specific vehicle signal, if available).
3.4. Rear View Camera Wiring (to Separate Display Screen)
If you are using a separate display screen (not an Android head unit), ensure it is compatible and has the necessary video input and power connections.
- Connect the camera's yellow RCA video cable to the video input of the separate display screen.
- Connect the camera's red power wire (DC 12V) to the vehicle's 12V+ reverse lights power source.
- Connect the camera's black power wire (GND) to a reliable ground point.
- Connect the display screen's 12V+ power wire to the vehicle's 12V+ reverse lights power source.
- Connect the display screen's 12V- power wire to a reliable ground point.
3.5. Functionality Control Wires
Your camera may include specific wires that can be cut to change its functionality:
- Front and Rear View Switching: Locate the designated wire (often green). Cutting this wire can switch the camera's default view between front and rear.
- Control Parking Line: Locate the designated wire (often white). Cutting this wire will enable or disable the parking guide lines displayed on the screen.


4. Operation
Once correctly installed, the camera operates automatically when triggered by the vehicle's electrical system (e.g., engaging reverse gear for a rear camera). The video feed will appear on your connected display unit.
4.1. Key Features in Operation
- 170-Degree Fisheye Lens: Provides a super wide viewing angle, minimizing blind spots.
- Night Vision: The camera is equipped with starlight night vision technology for clear images even in low-light conditions.
- Guiding Lines: If enabled, dynamic or static parking guide lines will appear on the screen to assist with parking maneuvers.
5. Maintenance
To ensure the longevity and optimal performance of your Smartour Car Camera, follow these simple maintenance guidelines:
- Cleaning the Lens: Regularly clean the camera lens with a soft, damp cloth to remove dirt, dust, or water spots that may obstruct the view. Avoid abrasive cleaners.
- Waterproof Design: The camera is designed to be waterproof, ensuring reliable operation in various weather conditions. However, avoid high-pressure washing directly on the camera.
- Cable Inspection: Periodically check all cables and connections for any signs of wear, damage, or corrosion. Ensure they are securely fastened.

6. Troubleshooting
If you encounter issues with your camera, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on display | Loose connections, no power, incorrect video input selected. | Check all video and power cable connections. Ensure the camera is receiving 12V power and ground. Verify the correct video input is selected on your display unit. |
| Distorted or flickering image | Poor connection, electrical interference, faulty cable. | Ensure all connections are secure. Check for any loose wires or damaged cables. Try rerouting cables away from other electrical components if interference is suspected. |
| Parking lines not appearing/disappearing | Control wire incorrectly cut or not cut. | Refer to Section 3.5 'Functionality Control Wires' and ensure the parking line control wire is in the desired state (cut or uncut). |
| Camera view not switching automatically | Display trigger line not connected or connected to wrong source. | Verify the 'BACK/Reverse' or 'Display Trigger Line' on your display unit is correctly connected to the appropriate 12V+ trigger (e.g., reverse lights). |
