I use the one from helmetcamera.com and the housing for the camera is a big plus. We have crashed alot wearing them and there is no damage to the camera. I am not sure if Viosport is the same camera because the one I use is submersable to 100'. I also just recieved me remote switch for it and it is great. Saves batt. life and you can record just what you want. If you want to see what they pics look like you can go to this thread
