Review on High Definition 4K Webcam with Built-in Microphone: Perfect for Video Calling, Conferences, and Streaming – Includes Privacy Cover and Mini Tripod – Ultra HD 8MP USB Webcam with 1080P Resolution by Durward Carlson

Need a 4K webcam for video conferencing (maybe for a group of people but apparently not yet) and occasional indoor video. This webcam has decent build quality and works almost as expected. It has a fixed focal length, so images won't automatically focus and blur here and there. I tried video conferencing scaling (make sure you set up microphone and video on that USB camera). The video quality is pretty good. The camera comes closer than the built-in camera, so sit a little further away. I assume this applies to video conferencing with a group of people. The microphone that came with the camera is of normal quality, very similar to the built-in microphone on my laptop. Voices at a distance of 4-5 meters were heard with good clarity. It is also very suitable for shooting practice with flexible angle adjustment while checking the result on the big screen. A remote control for the camera would be ideal. Given the price, I won't complain too much about it though. The only downside I found is that the viewing angle adjustment isn't smooth enough. Hope it gets better as it curls more.
