Most cameras feature an RJ45 port and a twisted pair-to-fiber optic media converter must be used. The media converter connects directly to a fiber-enabled network switch via fiber optic cable and matching SFP transceiver modules. Here are the steps to follow: Before installing any cables, you need to plan the layout of your security system. Fiber optics minimize long-distance issues and costs more than copper wiring.
