Adding a camera addon

Ok, so yeah its a picamera. No clue how to how to code this thing. I would like an addon that when launched, it starts recording. Maybe after 4gb is filled, it records over that file. Im using it as a dash cam. So far this is all I found and I dont know how to even download it so I can SSH it in to Kodi.
