I use something like this to power my Blackview DR900S. Plugs into OBDII so no messing with fuses or grounds. Very easy to run the cable where the headliner meets the windshield.
I used an add-a-fuse (search online). The wire was ran from my fuse box, up the A pillar, across the headliner, and down the mirror/lane-keep trim. Taking out the map light is key to routing into the mirror trim. It came out really cleanly.
I have mine plugged into the 12v outlet in the back. I routed the wires behind the headliner, then behind the A pillar, then under my weathertech floor liner, then under the seat and into the back. Not even noticeable
I used 2 Add-A-Fuse taps to take power of from the fuse panel on the lower drivers side. Ran the power cable tucked behind the headliner and windshield and then used a trim tool to route around and under the top of the A-Pillar and then down underneath the door weather seal to the fuse panel.
That was the easy part of the whole install. I have a 2-ch dash cam and had to run a USB cable all the way to the rear hatch... that took a lot of time and some choice words, but is totally clean, probably 2-3inches of cable show right at the back where it runs to the camera.

How did you ultimately attach the rear-facing camera? I have a 2 channel ordered, and I was thinking about how I would mount the rear camera. I would prefer to mount on the rear window, but I don't know how I would rout the attaching cable with the moving hatch. I would assume you would need to hide some slack somewhere in the setup?
The rear facing camera is stuck to the glass with double sided tape (came with the camera).
I ran the USB cable underneath the trim above the CHMSL. I had to remove that rim, and then ran the cable through the wire cover so it was completely hidden, and then underneath the roof liner until the rear door and then underneath the weather stripping on the doors.
The excess cable I cable tied and then used some foam tape to prevent rattling and tucked into the spare spaces along the way.
If you need I can take some pictures and markup where I ran the cable, but at the end of the day there is only a few inches showing at the rear.
The large plastic cover where the cable goes underneath in the picture above had to be removed so I could fish the cable through this sleeve/cover:
From there I ran the cable under the head liner right where the plastic trim is behind the rear headrest for a bit until the door.
Then at the door I ran the cable under the door weather stripping and the head liner.
Then fed it through under the headliner at the B pillar and then same thing as the rear door I ran it just under the headliner at the weather stripping on the door up to the A pillar.
From there just fed it under the top of the trim for the A Pillar and then up the headliner above the windshield to the front camera.
