I think many crews are looking at this the wrong way.
As Nick alluded to regarding flight test campaigns, a camera is a note-taker.
I have had the disappointing experience of trying to help an operator sort out
a strange issue twice now where they had a camera installed but the pilot unplugged it because he did not like "being spied on".
Ask yourself this: If you have serious malfunction in flight, are you going to be
Jotting down parameters on the way to the ground? The camera is there for you
and those trying to sort out the problem, not to tell the boss how you fly.
If your boss wants to know how you fly, an HFDM capable SAT Tracking system
will tell him all, without you ever knowing about it.
While not putting words in the mouth of anyone posting here, I have heard some very vocal individuals take the position of the "spying on me" set. These are the very same people who several years ago opined that they preferred older AS 350's to newer ones because those VEMD's would "tell on you"
