Beach camera setup

I've often wondered what the camera person is using for beach videos like ILoveTheBeach and BestToplessBeach.

They can't be standing there holding a camera because the subjects never seem to give much of a look. They are able to pan and ****m as the subject moves, so they can somehow see the video that's being captured. They also seem to be near the subject and not ****ming in from far away.

What are your theories for how they're able to hide the camera, but still pan and ****m while seeing what the camera is capturing?

sorry I don't know, but I have ALWAYS wondered the same thing
