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. This 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 streams to RTMP/SRT live media servers, making it suitable for network live broadcasts. With support for rtmps security protocols and SRT protocol, it can push media to multiple servers simultaneously. Additionally, the app can mix USB audio with built-in microphones or system audio, overlay internal camera footage onto external camera video, and record dual MP4 files synchronously when connected to two cameras. Users can also add timestamps, GPS data, and speed information on video frames during recording.

This app is particularly useful for content creators, security professionals, and anyone needing robust video recording and streaming solutions. Its ability to function as a dash cam with loop-recording and motion detection-based auto video recording adds to its practicality. The seamless switching between foreground and background ensures uninterrupted recording, enhancing user convenience.

USB Dual Camera Pro offers a comprehensive set of features designed to enhance video recording and streaming experiences. One of its standout features is the ability to connect two USB webcams or video capture cards simultaneously, supporting formats like MJPEG, H.264, H.265, HEVC, and AV1. This flexibility allows users to record in resolutions up to 4K via HDMI, accommodating both progressive and interlaced video formats.

The app includes a built-in RTSP and HTTP server, transforming your Android device into a wireless IP camera. This feature is complemented by bi-directional audio support, which requires the IP Camera App available on Google Play. Additionally, the app supports pushing video and audio streams to RTMP/SRT live media servers, including YouTube Live, using protocols like rtmps and SRT. This makes it highly suitable for professional live broadcasts.

Other notable features include the ability to mix USB audio with built-in microphones or system audio, overlay internal camera footage onto external camera video, and record dual MP4 files synchronously. The app also supports adding timestamps, GPS data, and speed information on video frames, loop-recording, and motion detection-based auto video recording. These features collectively provide users with powerful tools for creating high-quality video content and conducting effective security monitoring.

USB Dual Camera Pro demonstrates exceptional versatility in video format compatibility, ensuring a seamless experience for users working with diverse video sources. The application supports an extensive range of formats including MJPEG, H.264, H.265, HEVC, and even the newer AV1 codec.

This broad compatibility spectrum allows users to connect up to two USB WebCams or video capture cards simultaneously, provided the necessary format requirements are met. For instance, when using two cameras at once, MJPEG is required, while HEVC recording demands Android 5.0 or above, and AV1 streaming requires Android 10 or higher.

The benefit to users is significant, as they can work with high-resolution video inputs up to 4K via HDMI, accommodating both progressive and interlaced video types. This flexibility ensures that whether you're recording, live-streaming, or using your device as a wireless IP camera, USB Dual Camera Pro adapts to meet various professional and personal needs without compromising on quality or performance.

While USB Dual Camera Pro focuses primarily on video capture and streaming capabilities, it also incorporates AI-powered features that enhance the video production process. One notable feature is its ability to mix USB audio with built-in microphones or system audio, providing users with advanced audio control options during recordings.

The app goes beyond basic functionality by offering video overlays, allowing users to superimpose built-in camera footage onto external camera video. This capability, combined with automatic timestamp and GPS data overlay, creates professional-grade video outputs suitable for security monitoring and other specialized applications.

Furthermore, the application's motion detection-based auto-recording feature showcases its intelligent automation capabilities. When motion is detected, the system can automatically record video, upload it to an FTP server, and notify users via email. These AI-driven enhancements streamline workflow and improve efficiency for both casual users and professionals in fields such as surveillance and content creation.
