+  <summary>Expand: Using the `dashboard` cast method to cast a low latency live provider</summary>
+
+This example will configure a Frigate card that can cast a dashboard view to a media player, which has a second Frigate card in panel mode with a low-latency live provider.
+
+#### Source card
+
+```yaml
+type: custom:frigate-card
+cameras:
+  - camera_entity: camera.front_door
+    cast:
+      method: dashboard

+        view_path: front-door
+```
+
+#### Dashboard configuration
+
+This dashboard is configured at the path `/cast/` (path referred to in `dashboard_path` above).
+
+```yaml
+title: Frigate Card Casting
+views:
+  - title: Casting
+    # This path is referred to in `view_path` above.
