Audio cable vs. video cable?

Hey all - I'm wondering whether there is a difference between a cable coming out of a small camera that attaches to the rear of my eBike, and then plugs into a small (USB- rechargable) monitor screen on my handlebars vs. a stereo miniplug cable used with headphones, etc? The camera cable is a foot or two too short, so I am wondering whether an audio headset extender cable would successfully carry the signal and power between the camera and its monitor. I've been told that the camera cable has two insulated wires and a "metal" wire. Before I just plug it in and see what happens, I thought to ask here first. Thanks for any advice .
