Frequently Asked Questions
PoE vs PoE+ vs PoE++?
802.3af (PoE) supplies up to 15.4 W per port at the switch, 802.3at (PoE+) up to 30 W, and 802.3bt (PoE++) up to 60 W (Type 3) or 90 W (Type 4).
How much power does an IP camera need?
Most fixed IP cameras draw 4–12 W; PTZ and cameras with heaters/IR can require 25–60 W, so plan with PoE+ or PoE++.
What is a power budget?
It is the total wattage a switch can supply across all PoE ports at once. The sum of device draw plus cable loss must stay under it.
Do I need PoE++?
Use PoE++ (802.3bt) for high-power devices such as PTZ cameras, multi-radio Wi-Fi 6/7 access points and LED displays that exceed 30 W.
Per-port values are the IEEE maximums delivered at the switch (PSE side). Actual device draw varies — confirm with the device datasheet and leave headroom.
