This is the hardware that ties network gear together: PoE injectors that feed power to cameras or access points down the same network cable, SFP and SFP+ modules for fibre links, and media converters from fibre to copper. There are answers for older buildings too — Ethernet transmitters and receivers that run over coaxial cable, for when there is no way to pull a new network lead. When choosing an injector, power and standard are what count: PoE, PoE+ or Hi-PoE.
