Review on 8MP 4K HD USB Webcam with Microphone for Computer, PC, Mac, Widescreen Laptop, Full Widescreen USB Webcams, Privacy Shutter, Tripod, Video Calling and Recording by Buddy Colbert

We bought two of these which are now being returned. This is a 1920 x 1080 resolution camera at its best and it seems to be taking pictures of this size - see first image. It's certainly not 3840×2160 as advertised here on Revain or in the accompanying brochure and documentation. Also compare the two photos of the boats. One of the real 1920 x 1080 cameras compared to this so-called 4K camera. It appears to be upscaled from 720 x 480 to a scaled 1920 x 1080 output file, you can immediately see which is the correct one. Significant frequency banding is also present in the record. The audio from the microphone is also very poor with significant line noise and interference, this product is not as advertised. software stacks. It's slightly better than the laptop's built-in 720x480 webcam, but can't even recommend it as a 1920x1080 camera, let alone a "4K" device.
