When we moved across to Bristow and flew their nice new shiny S76C++, they had cockpit cameras directed on the instruments. None forward looking outside though as far as I am aware. It did feel a bit like being watched, but after a while you forgot they were there. Fly within the envelope and youve nothing to worry about. Fly outside the Ops manual limitations (unless in an emergency) and yes, they'd no doubt be able to use the footage to help them make some decisions.
