Hi all, Newbie here, with my first post! I've just purchased a new CCTV system. The cameras/system that came in the package also came with Premade cable. I therefore purchased Power and BNC connectors as my plan was to cut the pre-made ones off and re-crimp once through the wall to avoid a bigger hole (See below the/similar cable I have). My question is, am I able to do this? If I can't do this, what should I do? Either; order a drum of RG59 Shotgun? Or should I order CAT5 and some balun's
