!!!NOTE: Android 10 is not supported !!!
## Android newest SDK has issues to support Android 10 for OTG camera. And if I use the older SDK, it's not allowed to upload to Google Play. ##

The App is use for USB/OTG cameras which connected to Android Phones. It supports 1080p and 4K USB cameras live preview and video recording. Multi-Cameras connections supported.
With native video decode technologies, there is no obvious delays, and works well smoothly in HD video mode.
It supports Android 4.4 - Android 9. And it can be widely used for external USB cameras, USB endoscopes, USB otoscopes, USB microscope and so on.
Your phone/tablet must support OTG mode first.
