Power over Ethernet (PoE) is a system that passes electric power AND data on twisted pair Ethernet cables. In this case, a single cable is used to deliver both electric power and data to any compatible device (IP camera, VoIP phone, wireless access point etc.). More specifically, the data cable carries the electrical current. Continue reading “Understanding PoE (Power over Ethernet)”
