USB Camera

USB Camera is a handy mobile utility that lets you use your phone as a webcam. With a simple USB connection, you can quickly record video and take photos. You can also log in remotely to check recordings whenever you want.

By adding a microphone or using system audio tools, the app can handle different audio sources and support real-time video playback and live streaming, so you can match viewing to your preferences. It’s designed for broad device compatibility and can be installed on most mobile phones.

Key Features

• USB WebCam / Capture Card support: Connect an Android device to a UVC webcam or video capture card using USB-OTG. Record video, capture snapshots, or turn your phone into a wireless IP camera.
• Security monitoring: Built-in RTSP and HTTP Server enable security monitoring. With bi-directional audio, you can view via a browser (and you can also use the app’s “IP Camera” companion).
• Audio mixing & overlays: Mix USB audio with the built-in microphone or system audio output. You can also overlay the phone camera/screen feed onto the external camera video.
