  Connect the video cable to the camera

  If you need to connect a camera, you need to use the yellow video input connector mentioned above, and only this connector is for video input, and the other cables cannot use video signals! One end of the cable is connected to the yellow connector, and the other end has two prongs. When connecting to the camera, one end is connected to the GND bottom line on the camera, and the other end is connected to VCC. This completes the connection of the entire line.
