King Orry, I think a camera on a rider is good for documenting his travels and adventures, just a memory to have and look at a few years later. When I can't ride (especially in winter when the weather is miserable) and have some time to kill, I usually look at the videos I made 4-5 years ago and lots of memories come back. Back then I made the mistake to record too much boring footage but now, after few years of some experience I record only a few short clips of the key points (maximum 1 min) and then make a compilation (stick together and put some music on the background so I won't hear the wind noise but not to cover the engine sound). Is also good to share your experience and places that you have been with other people. I often find myself deep in YouTube watching random people adventures and travels...makes me go out more and explore.
At the moment I have some Chinese small camera fixed permanently, just under the headlights and is hard wired to the ignition. Every time I start the bike, the camera starts recording in a loop in 3 min segments until the memory card is full. Once is filled up (takes about 8 hours of recording) the oldest video is replaced by a new one. I use this for mostly for my own protection in eventually that something will happen and need to show it to the insurance or maybe became famous on YouTube
. Then I have my GoPro on the lid (only for important trips) where I "document" my travels. I just love keeping memories from all the places I have been, so mostly is for my own good. Hope this helps with your decision to have or not a video camera. I think these days are quite good and very easy to use.
