Snowboarding Helmets

I am looking to buy a camcorder for my fiance for Christmas but have no idea what to look for. I am hoping to get one to go on his helmet while he is snowboarding, is there even such thing? If so, what is the best brand? He would need a pretty user friendly one, hopefully something he could just plug into a dvd player or computer. Any info would help as I am completely clueless in this area. Thank you!
