Ok, I've seen it. Fake.
Is has an active cameraman and a very convenienlty shadowed Trump.
I thought the first part as well, but it's actually someone filming a screen which makes it look like an active camera man. If you note that, you'll see the source footage camera is locked.
Besides the convenient shadow (which is plausible given how soft hotel room lighting tends to be), also worth considering that if the Russian plan was to catch "bedroom action" on film, the spy camera is a little low as you can't see the surface of the bed, and if there was someone lying down you pretty much wouldn't see them or any action. So, quite the coincidence that the footage is framed that way. Indeed, if Trump was going to drag a chair over to the bed, he probably would have done it to the closer near side rather than into the corner, and he wouldn't have been in shot at all.
