UGREEN CM831 4K Webcam

1. Introduction

In today’s digital-first world, your webcam is your virtual handshake—it’s the first thing people see when you join a video call. Yet most laptop cameras deliver grainy 720p video with washed-out colors and muffled audio. When you’re interviewing for a dream job, pitching to a client, or teaching an online class, poor video quality undermines your professionalism.

Enter the UGREEN CM831 4K Webcam—a premium Ultra HD webcam that transforms your video calls from blurry to broadcast-quality. With a 8MP Sony IMX CMOS sensor, 4K resolution at 30fps, phase-detection autofocus, dual noise-canceling microphones, and a physical privacy cover, this UGREEN 4K webcam delivers studio-quality video and crystal-clear audio for all your virtual interactions.

At Calvantech, we’re proud to offer the UGREEN CM831 4K Webcam to customers across Kenya who demand genuine, high-quality accessories for their professional and personal needs.

3.1 4K Ultra HD Resolution – Eight Times the Detail

The UGREEN CM831 4K Webcam delivers Ultra HD video at 3840×2160 resolution and 30 frames per second. Powered by an 8MP Sony IMX CMOS image sensor, it produces sharp, detailed images with vibrant, true-to-life colors.

3.2 Phase-Detection Autofocus – Sharp in 0.7 Seconds

The UGREEN CM831 features advanced phase-detection autofocus technology that locks focus in just 0.7 seconds—significantly faster than traditional contrast-detection systems that can take up to 2 seconds. Whether you lean forward to demonstrate a concept, hold up a document, or move around during long calls, the camera locks onto you instantly.

3.3 Auto Light Correction – Look Great in Any Lighting

The UGREEN CM831 4K Webcam automatically adjusts color temperature and corrects low light, delivering studio-quality imaging even in dim environments. Whether you’re in a bright office, a poorly-lit home office, or backlit by a window, auto light correction ensures your face is clearly visible—not washed out or shadowed.

3.4 Dual Noise-Canceling Microphones – Crystal-Clear Audio

Built into the UGREEN CM831 are two omnidirectional noise-canceling microphones that capture clear, natural audio from all directions. With a pickup range of up to 5 meters (16.4 feet) , these mics are perfect for group calls, presentations, or when you prefer to lean back and speak naturally. The noise-canceling technology minimizes background distractions, ensuring your voice comes through loud and clear.

3.5 70° Wide Field of View – Perfect for Groups and Context

The UGREEN CM831 4K Webcam features a universal mounting clip that securely attaches to laptops, monitors, and TV screens. It rotates 360° for complete control over your framing.
