USB Dual Camera

USB Dual Camera lets your device connect to two UVC USB webcams or capture cards via USB‑OTG for simultaneous recording, streaming and monitoring. Record dual MP4 files synchronously (with separate audio tracks if available), mix USB and built‑in audio, overlay built‑in camera or screen video, add timestamps/GPS/speed overlays, and create side‑by‑side 3D (SBS) video. Turn your phone into a wireless IP camera with built‑in RTSP/HTTP server and bi‑directional audio, or push streams to RTMP/SRT media servers (including rtmps and HEVC/AV1 where supported). Background recording, seamless foreground/background switching, picture‑in‑picture, and live network broadcast make this ideal for live production, security monitoring, dashcam use, and remote streaming.

The Pro version adds saving to external SD or USB disk, loop‑recording, auto‑segmenting and auto‑delete, Picture‑in‑Picture, display on lock screen, auto‑record on connect and other advanced settings. Supports motion‑detection triggered recording with FTP upload and email alerts. Note: use a quality OTG cable and powered USB hub for reliable dual camera power; HEVC and AV1 require device codec support and Android 5.0+ / 10+ respectively. Camera permission is required on Android 9+ for full USB video access.
