Review on MOKOSE 4K USB Webcam with CS-Mount 5-50mm Telephoto Zoom Manual Lens and UVC Free Drive - Industrial Digital Camera by Anthony Colton

The camera itself came with large dust particles stuck between the IR filter and the sensor (so you can't clean or remove, without tearing the IR filter from the sensor) ) - can still be seen clearly in the image even at full focus through the lens, so it's obvious that no quality control checks what the image actually looks like on the production line. In addition, the lens itself was extremely sluggish in all three settings (iris, zoom, focus) and could not be rotated freely on any of the axes. All in all, not a bad little camera if the workmanship could be a tad better, but it's really better to go for the cheapest than this article or try to find something better - doesn't fit in between.
