The one in my video I own a few, it did have a Mic installed until I added a camera with Mic installed and I took that mic and used it with same camera the Amcrest 850EB. The Mic I use for most of my remote mic setups I do have 5 cameras that use different type but my PTZ cameras that I installed with Mic I use the Hikvision DS-2FP2020-A disc mic. For the splitter I use a FOE5912 from Amcrest. Bought it because it offers 5, 9 and 12v power output from 1 unit.
Sounds like you have your mind made up on a Solution so answered because you asked and maybe others that read and able to change out 2 RJ45 ends to 4 might find the solution cheaper and easier to get it working same day. I am Just a person with a Passion for Security cameras and trying to help others along the way.
