Have a Lorex IP camera. I cut the cable as I had trouble with the original connector. I discovered the 4 pair standard color twisted pairs but it also had 2 black and 2 red wires in the wire sleeve. When I put the standard wiring into a RJ45 Keystone set using both the T568A and T568B configurations. It did not work. Searching for solutions there was discussion of the color wires from the camera being different that the Ethernet twisted pair Cat5 colors. What should I do with the 2 red and 2 black wires? What is the correct RJ45 pinout colors?
