Does anyone know any obvious reason why a cat5 cable i have installed works when I connect via a cat5 faceplate and patch cable both ends but not when I connect my own rj45 jacks which then go on a rj45 directly into my nvr and camera. I have tried reterminating both ends over and over and believe the colour code is correct. It is for a hikvision nvr and Poe camera.
The cable even works as a standard Ethernet cable in my PC and I used method B. Attached picture, am I being stupid and done the rj45 back to front or something?
I have tested for continuity etc
