Frequently asked questions

Is a monthly subscription required?

No. DoorBird includes free cloud visitor history and local recording — there are no monthly fees to use the intercom or the app.

How is it powered and wired?

A single Ethernet cable via Power-over-Ethernet (PoE), or a DoorBird power supply. With PoE you don’t need a separate power run.

Does it work with my smart home?

Yes — Apple Home, Amazon Alexa and Google Assistant, plus professional platforms: Control4, Loxone, Crestron, KNX, URC, Synology, Fibaro, Homey, Yale and NUKI.

Do I need an indoor monitor?

No — you answer the door from the free DoorBird app on iOS and Android. Optional IP indoor stations are available if you prefer a wall unit.

Which phones does the DoorBird app support?

The free DoorBird app runs on current iOS and Android devices, for both live view and answering the door.

What finishes are available?
