👉 Po Engineering, or PoE (Power over Ethernet), is a technology that allows electrical power and data transmission over a single Ethernet cable. This means devices like IP cameras, wireless access points, and some types of switches can be powered and connected to a network using the same Ethernet infrastructure that carries data. The power is typically provided through a PoE+ standard, which supplies up to 15 watts of power, and PoE++ can deliver up to 30 watts. This innovation simplifies network setup, reduces cabling costs and complexity, and enhances security by minimizing the number of devices connected to open ports. PoE is widely used in enterprise environments, smart homes, and outdoor applications where power distribution via Ethernet cables is convenient and efficient.
