nExt Camera is an application that displays a live video feed from any UVC OTG compatible USB camera device. (no root required)

It let's you preview, take photos and record videos from external sources like endoscopes, microsopes, Webcams, Dash cameras, FPV Receivers, UVC analog video grabbers, HDMI capture cards, etc.

The app was built with top performance and quality in mind. It delivers video feed with almost no delay, which is great for FPV and gaming.

As of now, the app is still under development and the list of supported devices is expanding. So, if you encounter any issues, please report them to us in order to improve the application in future updates.
