How to fit a Storage Options bike cam helmet mount I recently bought a helmet and handbar moutable camera made by a firm called storage options.  The instructions do not explain how to fit the strap for helmet attachment.  It consists of a ring of elastic with a further piece of elastic attached at right angles to the ring to form a half circle above the ring.  The camera mount is at the T where this extra piece attaches to the ring, and is oriented in the same direction as the extra piece.

Here is a photo of the strap.  I think that the camera is supposed to be inserted in an upwards direction into the area above the buckle on the lower strap (although this doesn't seem like a secure mount).  



Here is a photo of the camera in situ on a helmet.  As you can see it's not entirely clear how the straps are arranged from this photo



Does anyone know how to fit this to my helmet (which has a sun visor and to the best of my knowledge is a Giro Venti)?
It's designed so the bit at the top of the picture wraps around the helmet like a headband while the part of the strap that is making a "U" in the picture goes across the top.

To keep it from coming off, you'll need it to be fairly tight. This is okay with the helmets that are similar to skateboarding/snowboarding helmets (hard shell), but can make some of the more pricey (lighter) bike helmets lose integrity.

If you aren't going hard down single track, this will probably be okay, but be ready for it to slip off if you are doing anything that rocks the boat much.
