I've bought a Contour Roam camera as an 'insurance policy' for the commute. I also bought the additional helmet mount, but it's designed for the side of the helmet. You can mount it on the top, but that tilts the camera 90 degrees, which has the effect of using the wide-angle setting to capture both your feet and the far distance down the road. Mounting it on the side, however, feels lopsided, despite only being a couple of hundred grams. I can feel the helmet tilting on my head, despite ensuring a snug fit. The camera has 2 mounting points - a slide rack on the side for the helmet mount that I bought, and a standard threaded mount underneath. I don't know if that would be strong enough to use in this scenario though.
So, I'm either looking for:
A way of mounting on the top, the right way up.
Or, a light to mount on the other side of the helmet and balance the weight out a little.
