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. It also works with non-UVC devices like USB Endoscopes, making it suitable for various professional and personal use cases.

Beyond basic camera functionality, the app can turn your phone into a wireless IP Camera through an integrated RTSP and HTTP Server, ideal for security monitoring with bi-directional audio support. Users can view the stream through their browser or dedicated IP Camera apps. Additionally, the app supports advanced features such as pushing video and audio to RTMP/SRT live media servers, useful for network live broadcasts.

The app's ability to mix USB Audio with built-in microphones or system audio, overlay internal camera footage onto external video, and record dual MP4 files synchronously makes it a powerful tool for content creators. With options for timestamp overlays, GPS data, speed information, and loop-recording, USB Dual Camera Pro is also suited for dashcam functionality. Its seamless background operation ensures uninterrupted recording during use.

USB Dual Camera Pro offers a comprehensive suite of features designed to enhance video recording and streaming capabilities. One standout feature is its ability to handle two cameras simultaneously, provided they use MJPEG, H.264, H.265, or HEVC formats. This dual-camera support extends to recording videos into separate MP4 files, including independent audio tracks if both cameras have audio inputs, and creating full Side-by-Side (SBS) 3D videos.

The app includes advanced broadcasting options, allowing users to push video and audio streams to multiple RTMP/SRT media servers at once. It supports modern codecs like HEVC and AV1 over RTMP, compatible with platforms like YouTube Live. Furthermore, the app provides flexible audio management by mixing USB audio with built-in microphones or system sounds, offering users extensive control over their audio output.

Additional functionalities include motion detection-based auto-recording, FTP upload of recorded videos, and email notifications. The built-in RTSP and HTTP server transforms your device into a wireless IP camera, complete with bi-directional audio when paired with the IP Camera app. Loop recording, timestamp overlays, and seamless background switching further augment its utility, making it adaptable for diverse scenarios ranging from security monitoring to vlogging.

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 spectrum of supported formats allows users to connect up to two USB WebCams or video capture cards simultaneously without facing limitations on video quality or frame rate.

The app's ability to handle video inputs up to 4K resolution via HDMI is particularly noteworthy. Whether dealing with progressive or interlaced video streams, users can expect consistent performance. For those looking to stream or record using advanced codecs like HEVC or AV1, the app sets minimum requirements clearly: Android 5.0 or above for HEVC and Android 10 or above for AV1, provided the device itself supports these codecs.

This level of compatibility ensures that whether you're involved in high-resolution video recording, live streaming, or security monitoring, USB Dual Camera Pro adapts to your needs. By supporting both standard and high-efficiency codecs, it caters to a wide audience ranging from casual users to professionals seeking robust solutions for their video projects.

While USB Dual Camera Pro primarily focuses on video capture and streaming capabilities, it also incorporates AI-powered features that enhance its functionality beyond basic operations. One standout feature is its ability to mix USB audio with built-in microphones or system audio seamlessly. This intelligent audio processing capability ensures that soundtracks are clear and synchronized with video feeds, providing a professional touch to recordings or live broadcasts.

Another innovative aspect is the automatic video recording based on motion detection. This smart feature not only initiates recordings when movement is detected but can also upload these videos to an FTP server automatically. Users receive email notifications, making it ideal for security monitoring applications. The integration of bi-directional audio support through RTSP and HTTP servers further exemplifies how AI enhances user interaction and control over their surveillance systems.

Additionally, the app's capacity to overlay timestamp, GPS, speed, and other information onto video frames during recording showcases its sophisticated data handling abilities. These overlays provide valuable context to footage, especially useful in scenarios such as dashcam usage. By combining traditional video functions with intelligent enhancements, USB Dual Camera Pro delivers a comprehensive toolset for modern content creators and security-conscious users alike.
