What Is PoE and How Does It Work?

PoE, defined by the IEEE 802.3af standard, allows devices to receive both data and power through a single Ethernet cable. It delivers up to 15.4W per port, making it ideal for lowpower devices like basic IP cameras, sensors, and VoIP phones.

Pros:

1. Simplifies cabling by eliminating the need for separate power adapters.
2. Costeffective for smallscale deployments.

Cons:

1. Limited power output (up to 15.4W).
2. Not suitable for highpower devices like PTZ cameras or advanced access points.
