UGREEN 4K USB Webcam (CM831, 30fps, Autofocus)

4K webcam that makes calls and streams look sharp

A UGREEN 4K USB webcam (model CM831) that captures Ultra HD video at 30fps with autofocus and dual noise-cancelling microphones.

It clips onto a laptop or monitor and works plug-and-play over one USB cable, so you look and sound clear on the day.

This is the UGREEN 4K USB webcam, model CM831, a plug-and-play upgrade over a built-in laptop camera.

It is built around an 8MP sensor that records Ultra HD 4K video at 30 frames per second, and it falls back to 1080p on hardware or software that cannot handle the 4K pipeline, with 1080p also running at a smoother 60 frames per second.

It uses Phase Detection Autofocus to keep faces sharp as a presenter moves, and it has a 70 degree field of view that frames one or two people well at a desk.

It carries two built-in noise-cancelling microphones, so a separate mic is not required for solo creators and small meeting rooms.

Connection is over a single USB cable, and a USB-A to USB-C adapter is included, so it works with modern laptops, desktop towers and tablets on Windows, macOS, Linux and Android with no driver install.

A sliding privacy cover closes over the lens when the camera is not in use, and a standard tripod thread on the base lets you clip it to a monitor or mount it on a tripod.

Every unit is tested for image, autofocus, microphone and USB connection before it goes out, so you rent a camera that just works instead of buying one for a single event.
