 - `camera.snap` waits `delayMs` (default 2000ms, clamped to `[0, 10000]`) after warm-up/exposure settle before capturing.
 - Photo payloads are recompressed to keep base64 under 5MB.
 
+## Linux node host
+
+The bundled Linux Node plugin adds camera capture to the CLI `openclaw node` service. It works on a headless host and does not require the Linux desktop app.
+
+Camera access defaults to off. Enable it under the plugin entry, then restart the node service so its Gateway advertisement is rebuilt:
+
+```json5
+{
+  plugins: {
+    entries: {
+      "linux-node": {
+        config: {
+          camera: { enabled: true },
+        },
+      },
+    },
+  },
+}
+```
+
+Requirements:
+
+- FFmpeg with V4L2 input, `libx264`, and AAC support
+- a `/dev/video*` device readable by the node-service user; on common distributions, add that user to the `video` group
+- for clips with the default `includeAudio: true`, a working PulseAudio server or PipeWire PulseAudio compatibility layer with a default source
+
+Linux returns capture-capable, readable V4L2 device paths from `camera.list`; FFmpeg probes each `/dev/video*` candidate and omits metadata or output-only nodes. Device `position` is `unknown`, so facing requests without `deviceId` produce one `unknown`-position photo or clip instead of claiming a front or back camera. Use `deviceId` when a host has multiple cameras. `camera.snap` uses FFmpeg input warm-up for `delayMs` and preserves aspect ratio while limiting width. `camera.clip` records microphone audio as the MP4 audio track; OpenClaw deliberately exposes no standalone microphone command.
+
+The plugin uses `libx264` for MP4 video and does not silently change codecs. An FFmpeg build without the required input or encoders returns `CAMERA_UNAVAILABLE`. Photos and clips that would exceed the 25MB base64 payload budget fail with `PAYLOAD_TOO_LARGE`.
+
+`camera.snap` and `camera.clip` remain dangerous commands. Add them to `gateway.nodes.allowCommands` only when you intend to arm capture; enabling the plugin alone does not bypass Gateway policy.
+
 ## Safety + practical limits
 
 - Camera and microphone access trigger the usual OS permission prompts (and require usage strings in `Info.plist`).

+## Linux node host
+
+The bundled Linux Node plugin adds `location.get` to the CLI `openclaw node` service, including headless hosts without the Linux desktop app. Location defaults to off. Enable it under the plugin entry, then restart the node service:
+
+```json5
+{
+  plugins: {
+    entries: {

+          location: { enabled: true },

+    },
+  },
+}
+```
+
+Install GeoClue2 and its `where-am-i` demo (`geoclue-2-demo` on Debian and Ubuntu). The node-service user must be allowed by the host's GeoClue policy and authorization agent.
+
+The plugin uses `where-am-i` instead of a sequence of `busctl` calls. GeoClue ties client creation, properties, start, updates, and stop to one D-Bus client connection; the demo keeps that lifecycle together while separate `busctl` subprocesses do not. No npm dependency is added.
+
+Linux maps `coarse`, `balanced`, and `precise` to GeoClue accuracy levels `4`, `6`, and `8`. It validates `maxAgeMs` against the returned timestamp. GeoClue's demo does not expose the selected provider, so `source` is `unknown`; `isPrecise` is true only when reported accuracy is 100 meters or better.
+
+Linux uses the same stable errors: `LOCATION_DISABLED`, `LOCATION_TIMEOUT`, and `LOCATION_UNAVAILABLE`.
+

+## Node capabilities
+
+The bundled Linux Node plugin gives the CLI `openclaw node` service device capabilities without requiring the desktop app. Commands are advertised to the Gateway only when their capability is enabled and the required local tool exists.
+
+| Capability                              | Default | Requirement                                                           |
+| --------------------------------------- | ------- | --------------------------------------------------------------------- |
+| Desktop notifications (`system.notify`) | On      | `notify-send` from libnotify and a desktop notification session       |
+| Camera photos and clips (`camera.*`)    | Off     | FFmpeg, V4L2 camera access, and PulseAudio or PipeWire for clip audio |
+| Location (`location.get`)               | Off     | GeoClue2 and its `where-am-i` demo                                    |
+
+Configure the plugin in `openclaw.json`:
+
+```json5
+{
+  plugins: {
+    entries: {
+      "linux-node": {
+        config: {
+          notify: { enabled: true },
+          camera: { enabled: true },
+          location: { enabled: true },
+        },
+      },
+    },
+  },
+}
+```
+
+Restart the node service after changing these settings. Availability is determined once per process and the node advertisement is rebuilt on restart.
+
+The Gateway approves the node's command and capability surface separately from device pairing. On first start, or after enabling more capabilities, approve the pending surface:
+
+```bash
+openclaw nodes pending
+openclaw nodes approve <requestId>
+```
+
+A node can be connected and device-paired while its effective `caps` and `commands` remain empty until this approval completes.
+
+Camera devices must be readable by the service user, commonly through the `video` group. Camera clips use the default PulseAudio or PipeWire source when `includeAudio` is true; microphone audio exists only as that clip track, not as a standalone command. Location requires the node-service user to be permitted by the host's GeoClue policy.
+
+`camera.snap` and `camera.clip` also require explicit Gateway arming through `gateway.nodes.allowCommands`. See [Camera capture](/nodes/camera) and [Location command](/nodes/location-command) for payloads, limits, and errors.
