This is useful when you want a setting to become a long-term default, such as a fixed resolution, frame rate, camera name, or synchronization mode. Device launch files are located in [orbbec_camera/launch](https://github.com/orbbec/OrbbecSDK_ROS2/tree/v2-main/orbbec_camera/launch). Choose the `*.launch.py` file that matches your camera model.
For example, modify the default camera name to `camera_02`:
```python
DeclareLaunchArgument('camera_name', default_value='camera_02')
