I am looking for cat 6 cable. I have to fit 3 cat6 wires through an opening about size of a quarter used to be an old a/c runoff through the wall. The runoff is not being used anymore. These wires will be used for my CCTV system I am wondering if these could carry enough power to these cams. I will be using an Amcrest 4 channel NVR that does 4k. What do you guys think?
