While Drift Innovation's new Drift HD is certainly not the first of its kind, it wins points for being a lot smaller than its kin. 25% smaller. That alone, rather than its familiar specs, makes it stand out as a helmet cam you'd want.
This little guy takes 9MP photos and shoots in 1080p with that 170° wide angle, rotating lens the X170 had. It's also got support for 32GB SD cards and has ports for micro-HDMI and 2.5mm mics. And it comes with its own wrist remote. All pretty nifty. But the best part is that it fits in your hand or on your helmet without weighing you down so much. $370. [Drift Innovation via Engadget]
