I have had this for a while now. It takes videos in full HD and can take a 32gb card. It's waterproof, has LED and infrared lighting.. and it was cheap.. so I'm not too worried if it gets knocked, lost, or knocked off. The clarity and wide angle lens works well. The colour balance is a bit iffy sometimes.
Just hooked it up to the ST for the ride to Kenilworth (while the tip-over cover is off).
