Best Helmet Cam???

The viosport would be your best bet out of those four. Coming in at 520 lines of Res. it's good.

I always recommend www.helmetcamera.com they have one that's 560. It also comes with a bunch of goodies, a protector for your camera that is pretty much unbreakable. Also the camera is attached with this Air force Velcro, Tested at 225mph so you can take it off and place at what ever angle you want ft/bk. (I have one, haven't got to use it that much but I like it)

Highest quality Sony Ex View chip available

Also if you want the Viosport go to www.viosport.com they have a bunch of packages.

Hope this helps, and do some looking around, I did for awhile before I got mine.

Really for Video quality like in the Bike Vids. They use a 16mm camera and strap it to their helmet. One crash bye bye 5grand

I have the helmetcamera.com camera and it works really well. I got the one with the screw together video wiring instead of the RCA type that can come unplugged. It has the solid aluminum housing that could take a hard direct hit and survive. I guess something inside could still break but you will not be able to crush it and there are no moving parts so chances are you wont be able to break it. Video quality is good but so are all the other ones using the Sony chip. You could get MUCH better if you mounted a camera right on your helmet because most cameras have optical (or digital) stabilization built in. That takes care of the jitters in the rock gardens. Plus video cameras have much better optics so you get better clarity and colors. Another thing is you can use your cameras built in settings like white balance which don’t work with remote cameras. And last, remote set ups typically only record audio to one channel. If your not using audio, then no big deal. But if you don’t want to mount the whole camera on your helmet, then helmetcamera.com or viosport.com are your next best affordable option.
