What is PoE (Power over Ethernet)?

Power over Ethernet does something clever. It lets one network cable carry both data and power.

Here is why that matters:

·         No need for separate power cables. That is one less thing to plug in.

·         Installation is easier. Costs go down too.

·         You get centralised power management. Everything controlled from one place.

·         Great for remote spots. Perfect for hard-to-reach devices.

What is a PoE Switch?

A PoE switch does more than connect devices. It also powers them.

Here are some devices that work with PoE:

·         IP cameras. Great for CCTV systems.

·         Wireless access points. Perfect for Wi-Fi coverage.

·         VoIP phones. Reliable desk phones.

·         Access control systems. Secure entry points.
