+# Ring
+
+[`new in v1.9.13`](https://github.com/AlexxIT/go2rtc/releases/tag/v1.9.13) by [@seydx](https://github.com/seydx)
+
+This source type supports Ring cameras with [two-way audio](../../README.md#two-way-audio) support.
+
+## Configuration
+
+If you have a `refresh_token` and `device_id`, you can use them in the `go2rtc.yaml` config file.
+
+Otherwise, you can use the go2rtc web interface and add your Ring account (WebUI > Add > Ring). Once added, it will list all your Ring cameras.
+
+```yaml
+streams:
+  ring: ring:?device_id=XXX&refresh_token=XXX
+  ring_snapshot: ring:?device_id=XXX&refresh_token=XXX&snapshot
+```
