Went back to windows and got it running on the CMS software but couldnt't see any further clues in there how to set it up in other software.
Encouraging that the stream is accessible not only from the mobile apps, but it makes me wonder what is different about CMS above and every other camera software, I must have tried 15-20 different ones on the mac and no joy.
Still no further forward in figuring out which type of stream it is either.
