Fiber replaces copper for video transmission when you need to cover long distances with high bandwidth. Video signals pack a lot of data, and copper (even twisted-pair) suffers from attenuation, EMI, and increasing costs as distances grow. Fiber optic links maintain signal integrity over long runs, support multiple high-quality streams (HD/4K), and are immune to electrical interference, making them the preferred choice for distant camera networks. Short-range video surveillance, inside a building or campus, can use copper Ethernet just fine, so fiber isn’t as necessary there. For this reason, the scenario described fits long-range video surveillance, not short-range.
