PoE vs PoE+ vs PoE++ Explained
Power over Ethernet (PoE) lets a single cable carry both data and power. The standard determines how much power each port can deliver.
- PoE (802.3af) - up to 15.4W per port, enough for basic IP cameras and phones.
- PoE+ (802.3at) - up to 30W per port, the common choice for CCTV cameras and access points.
- PoE++ (802.3bt) - up to 60W or 90W per port, for PTZ cameras and high-power devices.
What is PoE budget?
The PoE budget is the total power the switch can supply across all PoE ports at once. Check it against your devices so you never overload the switch. Browse PoE switches by budget to match your installation.
