I recently purchased a very cheap CCTV/DVR system but it should work for my basic needs. I am wondering what the cheapest/best working option is that I can use for running cable because the kit only came with 50 feet of BNC/DC Siamese cable and that is not long enough. Camera specs Ir Camera, video output - bnc 1.0vp-p 75n, power- 12v. looks like using cat5e / balun might be the easiest. thanks in advance
