PoE and Port Planner
Enter your cameras and access points and check whether the ports and total PoE budget of your switch are sufficient.
| Device | Quantity | Power consumption per unit (W) | Requires | Total (W) |

With PoE (Power over Ethernet), a device receives power through the network cable. Two things must match: each port must be powerful enough for the device (af, at, or bt), and the total of all devices must stay within the switch's PoE budget. So a switch with 8 ports and a 60 W budget cannot power four 20 W cameras, even though it has enough ports.
The standards deliver 15.4 W (af), 30 W (at), 60 W (bt type 3), and 90 W (bt type 4) at the switch side; the device itself receives less due to cable loss. The power consumption in the examples is an estimate: check the nameplate or specifications of your own device. Passive PoE (for example 24 V) is not compatible with these standards.
