I've bought a lot of cables lately and the last two I bought were genuine cables from this brand: black earth wire and white earth wire. You are definitely different. White is a lot thicker, even real coated copper wires are thicker and you have to push them through RJ45, I use straight through connectors and I really have to push them through a lot more than black wires. I currently have a camera that has a range of over 500 feet when powered over Ethernet. It's an 8-megapixel camera that works great along with about 8 other cameras.
