Recently a storm hit my area which caused my outdoor camera POE port to burn and become useless due to water damage. It's a good thing that my POE switch was not affected. Tried so hard to look for tutorial but not one has mentioned anything about repairs for TP LINK VIGI cams. For this camera I followed a third party wiring diagram.

The LAN that I use is a CAT6 cable around 30meters in length (not that significant to this but i just figured i'll mention it) with RJ45 T-568B wiring pinout. The order of color is as follows for the CCTV pinout (from left to right,1-8)

RJ45 T-568B: white orange, orange, white green, blue, white blue, green, white brown, brown
CCTV Pinout color: Orange, Yellow, Green, Purple,Gray, Blue, Brown, White (same as hikvision camera)

I also bought an RJ45 Ethernet coupler to accommodate the new male plug.
Now i got my camera up and running.

Hope this helps someone as much as it did to a non-professional, wanna-be repairman, DIY guy who wants to save a couple of bucks.

P.S I also found a thread with T568B but order of color is Orange,Blue,Purple,Brown,Yellow,Green,Grey,White (this did not work for me. But might work for you if my solution doesnt for you)
