I've been looking for a helmet camera (for safety/insurance reasons) and have seen the atc2k, atc3k, tachyon xc, and vholdr. Can any of these compare video quality-wise to a normal camcorder (For example, this one, which happens to be "shockproof")? The resolution on all of the models are the same (640x480), so how much variance is there in video clarity between the low end (atc2k), the high end (vholdr), and the camcorder?
One possible hinderance would be the battery life (40min with that particular camera), but keeping the lcd closed and buying extra batteries for $6 each on ebay could probably fix that. Another issue is water resistance - I'd rather not have full on waterproofing because it wrecks the sound, but is there any way to make a camcorder at least water resistant? As for size and weight, the camcorder in question is relatively low profile at .36lbs and 1.6" wide.
