USB Webcam for Online Training with 4K Video PDAF Autofocus Camera

The 921MAX USB Webcam for Online Training is developed to support professional online education, employee training, webinars, and virtual classroom environments. Delivering 4K Ultra HD resolution at 30fps together with 1080P at 60fps, it provides clear video quality for instructors, trainers, and presenters who require reliable visual communication.

Featuring an 83° wide viewing angle, the webcam captures instructors naturally while allowing sufficient workspace visibility for demonstrations, whiteboard explanations, and product presentations. This balanced framing helps create a more engaging learning experience without requiring constant camera repositioning.

The PDAF autofocus system quickly responds to movement, maintaining sharp image quality when trainers move around the workspace or present educational materials. Automatic focus adjustment reduces interruptions and allows instructors to concentrate on delivering content rather than managing camera settings.

The high-quality 6P optical lens with an F2.0 aperture produces detailed images under typical classroom or office lighting. Support for MJPEG and YUY2 output formats ensures compatibility with mainstream learning platforms and video conferencing software.

For audio performance, the webcam integrates dual stereo noise reduction microphones that capture speech clearly while reducing surrounding environmental distractions. Whether conducting online lectures, employee onboarding, certification courses, or live demonstrations, participants can hear voices more naturally and clearly.

The USB 2.0 plug-and-play connection enables quick installation without requiring additional software. Simply connect the webcam to a compatible computer and begin teaching or training using Zoom, Microsoft Teams, Google Meet, Skype, OBS, or other communication platforms.

Supporting Wins, macOS, Linux, Android, and Ubuntu, the webcam offers excellent compatibility across educational and corporate environments. Combining Ultra HD video, intelligent autofocus, stereo audio, and simple installation, the 921MAX provides an efficient solution for professional online learning and training applications.
