Well I didnt pay him for the cables, but told him via messages and verbally i want cat 6 for CCTV - as everything is open in the house, i have the option of still running cat6, probs cannot run them to the original location of the NVR i had planned (the loft), but I can change its location and still run cat 6 without having to chisel walls to get cables through..... im not sure though if its worth the effort, mate said he defo would change to cat6 while most floor boards are open - i'm really in 2 minds.
builder claims this is what all cctv cables are like, so he clearly isnt with the times of IP cameras
