UGREEN CM831 4K 30Hz USB Webcam with USB to Type-C Adapter (65381)
The UGREEN CM831 (SKU: 65381) is a professional-grade 4K USB webcam engineered to deliver crystal-clear, broadcast-quality visuals for high-stakes corporate video conferencing, Twitch and YouTube live streaming, remote teaching, and digital content creation. Built around an advanced 1/2.8โณ CMOS optical sensor, it captures rich, lifelike detail at true 4K Ultra HD (3840ร2160) resolution at 30fps and fluid 60fps at 1080p Full HD.
Equipped with ultra-fast Phase Detection Autofocus (PDAF) and intelligent automatic low-light exposure correction, the CM831 keeps your face sharp, focused, and naturally illuminated even in poorly lit home offices or backlit rooms. Integrated dual noise-canceling beamforming microphones capture crisp vocal clarity while suppressing distracting ambient chatter. Complete with an included USB-A to Type-C adapter and physical privacy shutter, pair your desktop workstation with high-speed USB-C to USB-C cables and rapid GaN wall chargers at Umrelo.
