CameraFi - USB Camera Webcam is a multimedia application developed by Vault Micro for mobile devices. It is a camera app that can be used to control various USB-based cameras or webcams. With it, users can take photos or record videos from their smartphones.

Just like with Webeecam Free, CameraFi - USB Camera Webcam utilizes smartphones to enable a more intuitive and user-friendly way to control USB cameras of different types. It even supports tablets for an even more spacious view of the various controls and options available for users to configure.

How does it work?

CameraFi USB Camera Webcam allows you to turn your smartphone or tablet into a viewfinder for various UVC (or USB Video Class) cameras and webcams. With their ever-growing display sizes, they enable you to see more and do more with external cameras. The app allows you to take photos and record videos up to 1080p. For the audio, it has a built-in mic or you can plug your own.

CameraFi's utility extends to other more specialized use cases, though. It can be used for more dramatic shots like macro photography. It can even be used for more applications that require precision, such as in medicine or if you're working with circuitry. You can use the video function as a sort of live feed for these types of requirements to get a better and up-close look at objects or details.

One nice feature is that it lets you seamlessly switch among devices if you have more than one plugged into your smartphone. The app can also serve as a simple file manager for your photos and videos. Before trying this app out, just make sure that your phone or tablet has USB OTG (on-the-go) support for it to work. It also does not work specifically with Android 7.0 (Nougat).

Solid viewfinder app for USB cameras

All in all, CameraFi is a good option to consider if you're looking for an app that you can use to control your USB-based cameras. It lets you capture both photos and videos, and it's capable of handling multiple devices plugged in at the same time. Aside from not working with Android Nougat, it is worth a try.
