USB CAMERA is a versatile and free Android app brought to you by US apps 2020. This handy tool, falling under the Utilities & Tools category, lets you connect an external camera like an endoscope camera, webcam, or USB camera to your Android device. The user-friendly interface guides you through the process: after launching the app and granting permissions, you'll check if your phone supports OTG. If so, connect your USB camera using an adapter (USB to micro USB OTG or type-c port), click 'open', accept the external camera's permission, and start viewing live images!

The app grants control over settings like resolution and contrast and allows you to capture pictures or record videos. It also includes an in-built gallery for easy management of your captures. But the utility of USB CAMERA doesn't stop at being a webcam app. It can serve as a home security camera, a mini wearable camera, or even partner with an endoscope camera Borescope for drain inspections.
