This splitter is pretty much impossible to fit into the PFA130-E. So I ended up modifying that box. The piece that mounts to the wall has a thread in the middle that sticks out about 1/8". I used a hole saw to cut that away. See PFA130-E-1.jpg. The biggest issue however was the cap that goes on that box. It has 3 stand-offs to accommodate other cameras. There is also a round rim in the center. That round rim I cut away with a 2.5" hole saw. There were still some stand-offs left that I cut away with an angle grind. See image PFA130-E-2.jpg. I know, not very nice but nobody will see it. So that the cables don't get cut I used a metal file. It was quite a bit of work but I like the end result. See PFA130-E-3.jpg. The blue cable (will be painted) leads to the other camera that is connected to the switch.
