Power over Ethernet, or simply PoE, refers to any of the several standards or ad hoc systems that pass both electric power and data on twisted-pair Ethernet cabling. It’s a more efficient transmission method, when compared to ordinary electrical wiring, which only supplies power and requires separate wiring for data. Because PoE transfers both power and data over Ethernet cable, less wiring is necessary, while keeping the electrical wiring intact.
Dahua Technology, a world-renowned video-centric smart IoT solution and service provider, has been constantly developing transmission technology and devices, based on customer’s application scenarios.
