What is PoE? (Power over Ethernet)

PoE (Power over Ethernet) is a technology that allows network cables (Ethernet cables) to carry both data and electrical power to devices over a single cable. This means you can power devices like IP phones, IP cameras, wireless access points, and IP paging systems without needing a separate power adapter or electrical outlet nearby. You will need a PoE network switch to power on the device.

It's especially useful for simplifying installations, reducing cable clutter, and powering devices in places where it might be hard to run electrical wiring.
