Recommend a small camera to put on a helmet? Want sound and decent resolution.?

the svp t100 , it is small and strong , and will take the rough and tumble , you will get the audio as well , it should take a few hits from paint if you clean it pretty quickly as well. i say this is the best because you can fold the viewfinder in and it will record still , it has good battery life , and the camera itself will record ongoing for 7-14 hours with a usb mobile charger .it is also cheap so when it does take a hit you wont cry to loud
