# Camera capture (agent)

OpenClaw supports **camera capture** for agent workflows:

- **iOS node** (paired via Gateway): capture a **photo** (`jpg`) or **short video clip** (`mp4`, with optional audio) via `node.invoke`.
- **Android node** (paired via Gateway): capture a **photo** (`jpg`) or **short video clip** (`mp4`, with optional audio) via `node.invoke`.
- **macOS app** (node via Gateway): capture a **photo** (`jpg`) or **short video clip** (`mp4`, with optional audio) via `node.invoke`.

All camera access is gated behind **user-controlled settings**.

## iOS node

### User setting (default on)

- iOS Settings tab → **Camera** → **Allow Camera** (`camera.enabled`)
  - Default: **on** (missing key is treated as enabled).
  - When off: `camera.*` commands return `CAMERA_DISABLED`.

### Commands (via Gateway `node.invoke`)

- `camera.list`
  - Response payload:
    - `devices`: array of `{ id, name, position, deviceType }`

- `camera.snap`
  - Params:
    - `facing`: `front|back` (default: `front`)
    - `maxWidth`: number (optional; default `1600` on the iOS node)
    - `quality`: `0..1` (optional; default `0.9`)
    - `format`: currently `jpg`
    - `delayMs`: number (optional; default `0`)
    - `deviceId`: string (optional; from `camera.list`)
  - Response payload:
    - `format: "jpg"`
    - `base64: "<...>"`
    - `width`, `height`
  - Payload guard: photos are recompressed to keep the base64 payload under 5 MB.

- `camera.clip`
  - Params:
    - `facing`: `front|back` (default: `front`)
    - `durationMs`: number (default `3000`, clamped to a max of `60000`)
    - `includeAudio`: boolean (default `true`)
    - `format`: currently `mp4`
    - `deviceId`: string (optional; from `camera.list`)
  - Response payload:
    - `format: "mp4"`
    - `base64: "<...>"`
    - `durationMs`
    - `hasAudio`

### Foreground requirement

Like `canvas.*`, the iOS node only allows `camera.*` commands in the **foreground**. Background invocations return `NODE_BACKGROUND_UNAVAILABLE`.

### CLI helper (temp files + MEDIA)

The easiest way to get attachments is via the CLI helper, which writes decoded media to a temp file and prints `MEDIA:<path>`.

Examples:

```bash
openclaw nodes camera snap --node <id>               # default: both front + back (2 MEDIA lines)
openclaw nodes camera snap --node <id> --facing front
openclaw nodes camera clip --node <id> --duration 3000
openclaw nodes camera clip --node <id> --no-audio
```

Notes:

- `nodes camera snap` defaults to **both** facings to give the agent both views.
- Output files are temporary (in the OS temp directory) unless you build your own wrapper.

## Android node

### Android user setting (default on)

- Android Settings sheet → **Camera** → **Allow Camera** (`camera.enabled`)
  - Default: **on** (missing key is treated as enabled).
  - When off: `camera.*` commands return `CAMERA_DISABLED`.

### Permissions

- Android requires runtime permissions:
  - `CAMERA` for both `camera.snap` and `camera.clip`.
  - `RECORD_AUDIO` for `camera.clip` when `includeAudio=true`.

If permissions are missing, the app will prompt when possible; if denied, `camera.*` requests fail with a
`*_PERMISSION_REQUIRED` error.

### Android foreground requirement

Like `canvas.*`, the Android node only allows `camera.*` commands in the **foreground**. Background invocations return `NODE_BACKGROUND_UNAVAILABLE`.

### Android commands (via Gateway `node.invoke`)

- `camera.list`
  - Response payload:
    - `devices`: array of `{ id, name, position, deviceType }`

### Payload guard

Photos are recompressed to keep the base64 payload under 5 MB.

## macOS app

### User setting (default off)

The macOS companion app exposes a checkbox:

- **Settings → General → Allow Camera** (`openclaw.cameraEnabled`)
  - Default: **off**
  - When off: camera requests return “Camera disabled by user”.

### CLI helper (node invoke)

Use the main `openclaw` CLI to invoke camera commands on the macOS node.

Examples:

```bash
openclaw nodes camera list --node <id>            # list camera ids
openclaw nodes camera snap --node <id>            # prints MEDIA:<path>
openclaw nodes camera snap --node <id> --max-width 1280
openclaw nodes camera snap --node <id> --delay-ms 2000
openclaw nodes camera snap --node <id> --device-id <id>
openclaw nodes camera clip --node <id> --duration 10s          # prints MEDIA:<path>
openclaw nodes camera clip --node <id> --duration-ms 3000      # prints MEDIA:<path> (legacy flag)
openclaw nodes camera clip --node <id> --device-id <id>
openclaw nodes camera clip --node <id> --no-audio
```

Notes:

- `openclaw nodes camera snap` defaults to `maxWidth=1600` unless overridden.
- On macOS, `camera.snap` waits `delayMs` (default 2000ms) after warm-up/exposure settle before capturing.
- Photo payloads are recompressed to keep base64 under 5 MB.

## Safety + practical limits

- Camera and microphone access trigger the usual OS permission prompts (and require usage strings in Info.plist).
- Video clips are capped (currently `<= 60s`) to avoid oversized node payloads (base64 overhead + message limits).

## macOS screen video (OS-level)

For _screen_ video (not camera), use the macOS companion:

```bash
openclaw nodes screen record --node <id> --duration 10s --fps 15   # prints MEDIA:<path>
```

Notes:

- Requires macOS **Screen Recording** permission (TCC).
