One cable, two jobs
Power over Ethernet, or PoE, carries both data and power over one network cable. Devices like access points and cameras need only that one cable.
Why installers love it
There is no need for an outlet at every device, so mounting on ceilings and outdoor walls is easier and cleaner.
The PoE switch
A PoE switch supplies the power. Each switch has a power budget, so the number and type of devices matter.
Sizing tips
Add up the devices, allow headroom and choose a switch with enough ports and power. Our PoE calculator does the math.
Backup power
A battery backup on the switch keeps cameras and Wi-Fi running during short outages.
