PoE budget.

Also written PoE power budget.

What is a PoE budget?

A PoE budget is the total power a switch can send down its network cables to cameras, access points and phones, summed across every port. It is the number that catches people out: a 24 port switch with a 250 watt budget cannot run 24 cameras drawing 12 watts each, whatever the port count says. Add up the real draw, then leave headroom.

Defined by IEEE 802.3af, 802.3at and 802.3bt, published by IEEE.
