How is the sound pick-up connected to the camera?
1.Standard 3.5mm headphone jack
The audio input port of the camera is connected to the 3.5mm wire of the pickup

2.bare wire
If the audio input/output of the device is bare wire, you will need two such ports : one input and one output (if you do not have one, you can cut two out of the cylinder).

Audio input: wind the orange and yellow wires together and then wind them with the camera audio input wire

Audio output: wrap the white and red wires around the camera audio output

After connecting the audio input and audio output, you will find that each interface has an extra strand of bare wire.Now wind the bare wire of the audio input, the bare wire of the audio output, and the ground wire of the camera together.
