title: "wendy device camera controls"
description: "Show a local camera's tunable controls (exposure, gain, white balance, ...)"
---

## Syntax

```sh
wendy device camera controls <id> [flags]
```

## Examples

```sh
wendy device camera controls --help
```

## Arguments

Argument notation from the CLI: `<id>`. Angle brackets mark required values; square brackets mark optional values. See Details for command-specific validation.

## Flags

Flags below include inherited options. Types and defaults come from the CLI source. An empty default means no value is configured.

| Flag | Type | Default | Description |
| --- | --- | --- | --- |
| `--device` | string | (empty) | Target device hostname; `wendy run` accepts a comma-separated list to deploy one build to several devices (needs a remote build host and --detach). Defaults to $WENDY_DEVICE, then the saved default device |
| `--json` | bool | `false` | Output in JSON format |

## Output

Output depends on the operation and selected target. Use the command help for additional guidance..

## JSON output

The global `--json` option requests machine-readable output. The CLI also selects JSON mode when no interactive terminal is attached. Support and payloads are command-specific; this flag does not guarantee a single JSON document for commands that stream logs or invoke build tools. Consult Details before parsing command output.

## Exit codes

The CLI entry point returns `0` on success and for its user-cancelled or default-cleared results. Other returned errors exit with `1` and print a diagnostic to stderr. Some operations may terminate through subprocess or signal handling; do not infer application health from the CLI exit code alone.

## Common errors

Check argument values and flag combinations against the synopsis above. For discovery, build, port, and readiness failures, see [deployment troubleshooting](../../../../../errors/). Command-specific constraints are in Details.

## Details

Show the tunable V4L2 controls a local (USB/CSI) camera exposes, with the
current value and the range each accepts.

The list comes from the camera itself, so it is whatever that hardware supports
rather than a fixed set -- a webcam with zoom or focus shows those too.

Run without an id to see which cameras this device has.

Use the command help for additional guidance.
