Im looking into buying a helmet camera, whats a good brand, i always see on ebays 420 and 520 verticle lines resolution, what the dif? also post pics of your camera set up
viosport makes good ones. more lines = better quality im most cases. i would suggest viosport tho. they are pretty well known and customer service is solid.
panasonic has a ill helmet cam it comes with one of their cameras and i think it will work with other cameras im not sure what its called tho but its advertised for sports
