What is the differece between POE+ and POE++?

Hi, dear!

Have a good day!

There are three general PoE standards:

PoE standard

The protocol number is IEEE 802.3af, which is the original PoE standard. 15.4W of power is output from the Ethernet port, and the output power 100 meters from the switch is 12.95W.

For more, see What is PoE (Power Over Ethernet).

PoE + standard

The protocol number is IEEE 802.3at, and PoE + doubles the output power of the Ethernet port. It can provide 30W power output, and the output power 100 meters away from the switch is 25.5W.

PoE ++ standard

Others call it Ultra PoE, UPoE or 4PPoE.

The protocol number is IEEE 802.3bt. This standard provides 60W-90W power output per port. Under the 60W standard, the output power of 100M from the switch is 51W.

The VCN510-8P, VCN510-16P, and VCN510-16PD provide eight PoE ports. The VCN can supply power to cameras through PoE ports, which helps users save camera power supply and switch costs.

The eight PoE ports include four PoE+ ports and four PoE++ ports. The maximum power of cameras that can be connected through PoE+ ports is 30 W. The maximum power of cameras that can be connected through PoE++ ports is 60 W. Additionally, the PoE++ ports can supply power to large-power PTZ dome cameras.

Best wishes!
