PoE vs PoE+ vs PoE++: What’s the Difference?
PoE, PoE+, and PoE++ all carry network data and DC power over an Ethernet cable. The main difference is the amount of power they can deliver. Basic PoE works for many low-power devices, such as IP phones and some PoE IP cameras. PoE+ provides more power and is commonly used for PTZ cameras and wireless access points. PoE++ uses IEEE 802.3bt Type 3 or Type 4 to power network devices with higher power requirements.
