IEEE 802.3af (PoE)

IEEE 802.3af, commonly known as Power over Ethernet (PoE), is a technology that allows electrical power to be sent over standard Ethernet cables alongside data. This means devices like security cameras, VoIP phones, or wireless access points can receive both power and network connectivity through a single cable, reducing the need for separate power adapters and outlets. PoE simplifies installation, improves device placement flexibility, and ensures reliable power delivery, making network setups cleaner and more efficient without additional wiring or power sources.
