Yes, our bodycam is equipped with a 1/4" mount thread, so you can mount it on your bicycle bracket. 

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. 

Simple, u turn the plastic bracket around, fit the sq plastic in the other way, then get a wall bracket and pipe and mount your unit on the pie and finally on the wall 

No, it’s only for Leica m mount. You will need a different version for l mount. 

Yes, it is indeed Nikon f mount.
