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. 

Perfect for placing in a tree. Easy to install and remove, no trouble securing camera. 

Has a 1/4 threaded connection for use with a tripod 

I have used one on a Sony a7 mkii.
