Sena Prism Mounting

Just got a Sena Prism bluetooth camera. Anyone have a preference or recommendation for the best location for mounting it? It's brand new, and I am just using it to keep track of my back-and-forth to work and the countless crazy drivers I encounter here in Silicon Valley. RIght now, I have it on the right side of my helmet just to the rear of the emergency pulltab for my Shoei GT Air helmet neck/cheek pad, but I feel like I lose a good amount of field of view on the left side. It's not horrible, but I just don't know if it COULD be better elsewhere. I'm not averse to mounting it on the bike as well, but then I feel like I'll lose out on which way my head is turning as I ride.

I suppose it would be the same for a GoPro or any other type of helmet/bike-mounted camera, not exclusively the Sena.

Thoughts?

Thanks!
