Mount Bolt in wall behind tv?

I am trying to figure if I can mount the Bolt on it's side in a recessed in-wall shelf, just around the corner from a wall mounted tv. I might have to do it on it's side there, because the spacing between the studs might be narrow there. The Bolt doesn't need line of sight, does it?

the only other thing I could try is mount it behind the TV, but I figure its too big and heavy for that. I'll do that with the appleTV.
