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.
