App summary
CameraFi — USB Camera Webcam is a multimedia app from Vault Micro that transforms Android phones and tablets into controllers and displays for USB cameras and webcams. It lets users capture photos and videos directly from external UVC (USB Video Class) devices and also provides simple file management for the media you create.
How it operates
The app connects to UVC-compatible cameras via USB OTG (on-the-go) and uses your mobile device as a live viewfinder. Larger tablet screens give a more spacious interface for framing and adjusting settings. Video can be recorded up to 1080p, and audio can come from the device’s built-in microphone or an external mic you attach.
Notable capabilities
- Record video at Full HD (1080p) and capture still images from attached USB cameras.
- Switch quickly between multiple connected devices when more than one camera is plugged in.
- Use the app as a basic gallery to browse and manage captured photos and clips.
- Accept audio input from either the phone/tablet’s mic or a connected external microphone.
Practical applications
- Macro and close-up photography where a live, magnified view is helpful.
- Precision work such as electronics inspection or surgical/medical imaging that benefits from a steady, zoomed live feed.
- Any scenario needing a portable external-camera viewfinder (e.g., product photography, documentation, live demonstrations).
Compatibility and limitations
- Requires a phone or tablet with USB OTG support to communicate with external cameras.
- Designed for UVC-compliant cameras and webcams.
- Not compatible with devices running Android 7.0 (Nougat).
Bottom line
If you need a straightforward way to use USB cameras with a handheld device, CameraFi provides a practical and user-friendly solution. It supports Full HD recording, multiple camera connections, and simple media management, making it a solid choice for hobbyists and professionals who want an adaptable mobile viewfinder.
