Review on 📷 SVPRO 8MP USB Camera with Varifocal Lens, Manual Zoom, and High Definition Webcam 2448P HD Mini Camera, Compatible with Android Windows Linux Mac OS, Plug and Play UVC Camera by James Hounds

I bought this to take readings on equipment during a research test. It had a good zoom and met the requirements. It was very difficult to get the focus right as the focus ring was very sensitive to small movements. You need a thinner thread. The resolution is probably not what is advertised as there is no compression and the files are not large enough to support 8 megapixels.
