USB Dual Camera Pro is a versatile video application that allows Android devices to connect to two USB WebCams or video capture cards simultaneously via USB-OTG. The app supports UVC WebCams with microphones and video grabbers with audio input, enabling users to record high-quality videos or capture snapshots. It also features an RTSP and HTTP server for turning your phone into a wireless IP camera, ideal for security monitoring with bi-directional audio support.

The app's advanced capabilities include pushing video and audio to RTMP/SRT live media servers for network broadcasting. It supports modern protocols like rtmps and SRT, and can handle multiple media servers simultaneously. With support for HEVC/AV1 codecs over RTMP, it's compatible with platforms like YouTube Live. Users can also mix USB audio with built-in microphones or system audio, overlay internal camera footage onto external video feeds, and even create full Side-by-Side 3D videos.

Designed for both casual and professional use, the app offers practical features such as timestamp overlays, GPS data integration, and speed information on video frames. Its loop-recording function makes it suitable as a dashcam solution, while motion detection-based recording provides automated security monitoring. The app ensures uninterrupted recording during background operation and requires minimal permissions, making it a reliable choice for various video capturing needs.

USB Dual Camera Pro stands out with its ability to handle dual cameras simultaneously, supporting resolutions up to 4K through HDMI. The app requires MJPEG or H.264/H.265/HEVC formats when using two cameras concurrently, ensuring smooth performance across different devices. It is compatible with Windows Hello Cameras and IR Cameras, and even supports non-UVC devices like USB Endoscopes, providing flexibility for various use cases.

The app's built-in RTSP and HTTP server transforms Android devices into wireless IP cameras, perfect for remote monitoring. Its RTMP/SRT streaming capabilities support secure protocols (rtmps) and simultaneous multi-server broadcasting. The app can mix audio from different sources and overlay video streams, creating professional-grade content. Additionally, the dual recording feature saves videos in two separate MP4 files while optionally recording audio independently, offering comprehensive media management.

Advanced functionalities include adding metadata such as timestamps and GPS coordinates to video frames, enhancing the value of recorded content. The loop-recording feature automatically segments videos and deletes older files when storage is limited, functioning effectively as a dashcam. Motion detection triggers automatic recordings, which can be uploaded to an FTP server and notified via email. These robust features make USB Dual Camera Pro a powerful tool for both personal and professional video applications.

USB Dual Camera Pro demonstrates exceptional versatility in video format compatibility, ensuring smooth operation across a wide range of codecs and resolutions.

The application supports industry-standard formats such as MJPEG, H.264, H.265, HEVC, and even the emerging AV1 codec. This comprehensive support allows users to connect up to two USB webcams or video capture devices simultaneously, provided the appropriate format is used. For instance, when using two cameras at once, MJPEG is required.

Notably, for advanced functionalities like HEVC video recording or streaming, the app requires Android 5.0 or higher, while AV1 streaming necessitates Android 10 or above. These requirements ensure optimal performance and access to cutting-edge features on compatible devices.

This extensive format compatibility provides professionals and enthusiasts with the flexibility to choose the best configuration for their specific needs, whether it's for high-quality video production, live streaming, or security monitoring applications.

Beyond its core functionality as a dual camera interface, USB Dual Camera Pro incorporates sophisticated AI-powered editing features that enhance the video production workflow.

The application's AI capabilities enable seamless audio mixing from multiple sources, including USB audio devices, built-in microphones, and system audio. This intelligent audio processing ensures professional-grade sound quality in recordings and streams.

Additionally, the software features advanced video processing algorithms that can overlay timestamp information, GPS data, and speed metrics directly onto video frames during recording. The AI engine also facilitates smooth video compositing, allowing users to overlay built-in camera footage onto external camera video feeds automatically.

These AI-powered enhancements streamline the post-production process by embedding valuable metadata and creating composite video streams in real-time, saving users significant time and effort in their video editing workflows.
