5. Setup and Installation
The Wkzay WK2 camera is designed for easy installation, particularly when integrating with an S21 system. Follow these general steps:
- Prepare the Vehicle: Ensure the vehicle is off and the parking brake is engaged. Disconnect the negative terminal of the vehicle's battery.
- Mount the Camera:
- Position the camera securely behind your vehicle's license plate. The camera is designed to integrate with the license plate mounting area.
- Use the provided mounting hardware to fasten the camera firmly. Ensure the camera lens has an unobstructed view.
- Route the Wiring:
- Carefully route the camera's power and video cables from the license plate area into the vehicle's interior. Avoid sharp edges or moving parts that could damage the cables.
- Utilize existing grommets or drill new holes (if necessary, seal properly) to pass the cables through the vehicle body.
- Connect to S21 System:
- Connect the camera's video output cable to the video input of your S21 system's display unit or receiver. Refer to your S21 system's manual for specific video input ports.
- Connect the camera's power cable to a 12V DC power source that is activated when the vehicle is in reverse. This is typically achieved by tapping into the vehicle's reverse light wiring.
- Ensure all connections are secure and properly insulated.
- Test the System: Reconnect the vehicle's battery. Put the vehicle in reverse (with the engine off and parking brake engaged) to test the camera feed on your S21 display. Adjust the camera angle if needed.
Note: For detailed wiring diagrams and specific S21 system integration instructions, please refer to your S21 system's user manual.

7. Maintenance
To ensure optimal performance and longevity of your Wkzay WK2 camera, follow these maintenance guidelines:

- Cable Inspection: Inspect the wiring for any fraying, cuts, or exposed wires. Repair or replace damaged cables immediately to prevent electrical issues.
