Does the crew know everything they do is being filmed?

If you saw the series finale you see Riker going into the holodeck on the Enterprise D in the 24th century and he calls up a program showing the NX Enterprise on its final mission and somehow everything on the ship apparently was filmed cause it seemed like Riker could listen in on anybody's conversations. He even sits in for "Chef" and gets first-hand comments from all the crew. He tells them they don't have to worry cause he keeps secrets. Perhaps but apparently Starfleet doesn't cause they go and put it in their holodeck library of programs? Snowden had it right, in the future everyone will be monitored at all times. Shades of the NSA.

And how did they get shots of the crew sitting in their rotten nose-bleed seats watching Archer giving his speech before the conference? They must have cameras everywhere, assuming this is an historical accurate representation what was really happening and not just something the computer speculates on and generates.
