+## `doorbell`

+Turns the card into a phone-style ringer that answers a [two-way audio
+call](../usage/2-way-audio.md) when somebody presses a doorbell. Intended for a
+wall-mounted tablet sitting on a dashboard with a doorbell camera.
+
+Minimal configuration — just point it at a doorbell-capable camera:
+
+```yaml
+type: custom:advanced-camera-card
+cameras:
+  - camera_entity: camera.front_door
+profiles:
+  - doorbell
+```
+
+> [!NOTE]
+> For inbound audio to actually work the camera still needs a live provider that supports two-way audio (e.g. `go2rtc` with `webrtc` mode). The profile does not change `live_provider` since that's setup-specific.
+
+See the [source code](https://github.com/dermotduffy/advanced-camera-card/blob/main/src/config/profiles/doorbell.ts) for an exhaustive list of options set by this profile.

 ## `low-performance`
 
 For low end devices, the `low-performance` profile will adjust card defaults to attempt to increase performance.
