**Complete Settings Reference**

**#### Camera & Capture**

| Setting | Default | Options / Range | Effect |

|---------|---------|-----------------|--------|

| ****Preferred camera**** | Dino-Lite | `dino_lite`, `usb_camera`, `auto_detect` | Pre-selects the camera source on the camera mode selector page |

| ****Default zoom**** | 1.0× | 1.0× – 4.0× | Starting zoom level applied when the standard camera opens |

The zoom slider maps a stored value of 0.0–1.0 to a display range of 1.0×–4.0× (formula: `display = 1.0 + stored × 3.0`). Setting zoom to 0 stored = 1.0× display (no zoom).
