Plug and Play 4K Webcam with PDAF Autofocus for Business Communication

The 921MAX Plug and Play 4K Webcam is developed for users seeking an efficient and easy-to-deploy video solution for business communication, online collaboration, education, and professional conferencing. Supporting 3840 × 2160 Ultra HD resolution at 30fps together with 1080P at 60fps, the webcam delivers detailed image quality and smooth video performance suitable for everyday communication.

One of the key advantages of the 921MAX is its plug-and-play USB connectivity, allowing immediate installation without additional drivers or software. This simplifies deployment for both individual users and enterprise IT teams, making the webcam suitable for office workstations, conference rooms, remote employees, and educational institutions.

The webcam features an 83° field of view, providing a comfortable framing angle for single users and small collaborative meetings. The carefully optimized viewing angle helps create a professional appearance while maintaining natural facial proportions, making it suitable for customer presentations, online consultations, webinars, and virtual interviews.

The integrated PDAF autofocus system continuously monitors subject distance and rapidly adjusts focus whenever movement occurs. Users remain sharp throughout presentations, product demonstrations, or online discussions without requiring manual adjustments. This intelligent focusing capability enhances the overall meeting experience while improving communication efficiency.

Built with a precision 6P optical lens and F2.0 aperture, the camera provides balanced brightness and sharp image quality under common office lighting conditions. Support for MJPEG and YUY2 formats ensures compatibility with mainstream operating systems and video conferencing applications while maintaining stable video output.

Audio performance is equally important during professional communication. The dual stereo noise reduction microphones capture voices clearly while reducing unwanted background sounds commonly found in office environments. This helps improve voice intelligibility during remote meetings, online teaching, business negotiations, and customer service interactions.

Compatible with Wins, macOS, Linux, Android, and Ubuntu, the 921MAX supports a wide variety of devices and conferencing platforms. Combining simple installation, Ultra HD imaging, autofocus performance, and clear stereo audio, it offers a practical webcam solution for business professionals, educators, and enterprise users.
