Hi! So the port on my Reolink camera went bad it is a B500 model. I don’t like it when technology doesn’t work so I got to work on it. I spliced the section where the port was and spliced a belkin in cat5e Ethernet cable I had. I connected solid gray from the Reolink to solid blue on the belkin, solid purple from the Reolink to white with brown from the belkin, then orange to orange, green to green, orange with white to orange with white, and green with white to green with white. I then connected the other end to a coupler and connected it to the Ethernet cable that’s going to the nvr (provided eith Reolink kit).
I’m sure you could direct wire it this way as well if you do not have a coupler.
