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 high-quality video recording up to 4K resolution through HDMI. It also features MJPEG, H.264, H.265, HEVC formats for dual camera usage, making it ideal for users who need advanced video capabilities on their mobile devices.

Beyond basic video recording, the app transforms your phone into a wireless IP camera with bi-directional audio support through an integrated RTSP and HTTP server. This functionality is perfect for security monitoring, allowing users to view live streams directly in their browsers. Additionally, the app can push video and audio to RTMP/SRT live media servers, supporting secure protocols like rtmps and SRT, which makes it suitable for network live broadcasts on platforms such as YouTube Live.

The app's ability to mix USB audio with built-in microphones or system audio, overlay internal camera footage onto external video, and record synchronized dual MP4 files adds immense value for content creators. With features like timestamp overlays, GPS data, speed information, and loop recording, USB Dual Camera Pro serves as a comprehensive tool for both professional videography and personal use cases like dash cams.

USB Dual Camera Pro offers a rich set of features tailored for advanced video operations. One standout capability is its support for dual cameras, allowing simultaneous connection of two USB webcams or video capture devices. This feature is particularly beneficial for users who require multi-angle shots or need to record from different sources at once. The app ensures smooth performance by recommending the use of powered USB hubs, especially when working with resource-intensive devices like Elgato Cam Link.

Another remarkable feature is the app's integration of an RTSP and HTTP server, turning your Android device into a wireless IP camera. This functionality supports bi-directional audio, enhancing its utility for security monitoring. Users can access the live feed through any browser, providing flexibility and ease of use. Furthermore, the app's compatibility with RTMP/SRT live media servers enables seamless live streaming with support for modern codecs like HEVC and AV1, ensuring high-quality broadcasts even on slower networks.

Additional functionalities include audio mixing, video overlays, and side-by-side 3D video creation. These tools allow users to produce professional-grade content by combining multiple audio and video sources. The app also supports motion detection-based auto-recording and FTP upload notifications, adding convenience for surveillance purposes. With these robust features, USB Dual Camera Pro stands out as a powerful solution for both amateur and professional videographers.

USB Dual Camera Pro demonstrates exceptional versatility in video format compatibility, ensuring a smooth experience across various codecs and resolutions. The application supports an extensive range of video formats including MJPEG, H.264, H.265, HEVC, and even the emerging AV1 codec.

This compatibility is crucial for users who work with multiple cameras simultaneously, as it allows them to utilize up to 4K resolution via HDMI, accommodating both progressive and interlaced video streams. Such flexibility ensures that whether you're recording high-definition content or streaming live events, USB Dual Camera Pro can handle the technical demands.

Moreover, the requirement of Android 5.0 or above for HEVC and Android 10 or above for AV1 showcases the app's commitment to leveraging the latest technology standards. This forward-thinking approach guarantees that users can take full advantage of modern device capabilities without worrying about format restrictions.

By supporting these advanced codecs, the application not only enhances video quality but also optimizes storage usage and transmission efficiency, providing users with a professional-grade tool for their multimedia projects.

While USB Dual Camera Pro primarily focuses on video capture and streaming, it incorporates several AI-powered features that significantly enhance the video editing process. One notable capability is its automatic audio mixing function when using two cameras with audio input, which intelligently balances sound sources for optimal output.

The application's sophisticated timestamping feature automatically adds GPS coordinates, speed information, and other metadata directly onto video frames during recording. This AI-driven functionality proves invaluable for professionals requiring detailed documentation of their footage, such as security monitoring or dashcam applications.

Furthermore, the built-in motion detection system represents another AI-powered innovation. It enables automated video recording based on detected movement and can even upload recordings to an FTP server while notifying users via email. This intelligent automation streamlines workflow and ensures important events are captured without constant manual supervision.

Additionally, the app's ability to create full Side-by-Side (SBS) 3D videos demonstrates its advanced processing capabilities. While not traditional editing features, these AI-enhanced functions provide users with powerful tools to produce more informative and technically sophisticated video content.
