The story behind it. Someone found debris of a fairing in the sea at the Bahamas and it included a GoPro camera attached to it. Until that find it was unknown that there are cameras in the fairing. After it became known SpaceX released this video. A must see, just beautiful.

SpaceX had announced that they are working on recovering and reuse of the fairings. That's probably why the cameras are there.
