Power Over Ethernet (PoE) vs Power-Line Networking

What is the difference between the two? Both serve the same purpose; to provide data as well as (electrical) power to different nodes. I can't seem to find the difference

PoE is used to provide electrical power to a device, such as a camera, as well as carrying the signal from the camera back to the switch or DVR.

Powerline networking is delivering an ethernet signal through the house electrical wiring, to a second powerline device.
This is done in place of running a regular Cat5e cable, or WiFi.


Think of it as:
Power over Ethernet
vs
Eternet over powerlines

PoE is when electrical power is supplied via unused wire pairs in Ethernet cabling.

Powerline Ethernet is when Ethernet signals are modulated over electrical power lines, such as in a home.
