The PoE Over 2-Wire Retrofit Extender is a networking solution designed to deliver both data connectivity and Power over Ethernet across existing two-wire or coaxial cabling infrastructure, eliminating the need for costly cable replacement projects. Ideal for retrofitting older buildings, apartment complexes, hotels, schools, offices, industrial facilities, and surveillance installations, it enables modern IP devices such as cameras, access control systems, and network equipment to be deployed using pre-existing wiring. By extending Ethernet and PoE connectivity over long distances, it helps simplify upgrades while reducing installation time, labor costs, and infrastructure disruption. Its compact design, flexible mounting options, and support for PoE-powered devices make it an effective solution for modernizing legacy cabling environments and expanding network capabilities without extensive construction work.
