I'd like recommendations on high quality camera preferably that can mount of helmets and can record the front and back. I saw some posts on other sites mentioning some crazy dudes just hitting people with their cars/car doors for fun even though they are in the bike lane. If I'm going to get hit I want to at least get some evidence of it and anything to identify them. Budget is $200 but prefer to be lower than that however if it's worth it I'd go over that amount.
