There should be some kind of shoulder and neck brace thing which helps secure the camera. Or attach it to a helmet of some sort, like those lamps on spelunkers.

Don’t ever let happen what happened the other week, when two score people passed a man who badly needed oxygen and maybe first aid, and no one stopped to help him.

”...no less than 40 mountain climbers on their way to the summit of Mount Everest ignored a fellow climber dying of oxygen starvation, 34 year old Briton David Sharp.”

I think you may be able to strap the camera on your head like a lamp. There will be a way. Your dream gives you the chance to be more than just a transient or sedentary being, staying alive like a lichen on rock. Dare to be! Dare to climb!
