Shooting with two camcorders, record the audio separately, mix it on the timeline in post. Your camcorders will have audio on the file, use it sync your videos. When recorded by a device that is not a camcorder, placed on the timeline and the video built around it, it is an easy edit to do. You could sync with Clap of your hands, but if the camcorders are going on and off, that is not practical at all.
