Yes, our underwater camera for snorkeling supports instant playback of videos directly on the device, and you can also upload videos to a PC for viewing. 

Yes, it comes with a mount which is a plastic pipe with a pivot at the base. I'm sure you could mount the station itself on the same size pipe. The hardest thing would be getting it level. I'm not sure what diameter the pipe is but I would guess the outside diameter is around 1 in. The pipe in the picture is part of the base, and the unit sits over the end of the pipe. Hope this answers your question. 

Don't think so just put up a longer pole and take some hose claps and strap to the longer pole two should be more than enough I screwed mine to the peak of the house some time you can't get perfect north south pole is a good deal 

I haven’t used it for sports but it has a pretty fast zoom, so I would assume that itv would do just fine.
