This is a Logicool/Logitech BRIO C1000eR webcam with a built-in microphone that can record high-resolution video. It's in near-new condition, having only been used for a few days, and comes with the original plastic cover and box.

However, while I confirmed that the high-resolution camera and microphone performance were excellent, the infrared facial recognition didn't work properly on my company PC. (This may have been due to the company PC not having administrator privileges.) I've decided to continue using my previous webcam, which uses only the standard Windows driver and works with Windows Hello facial recognition, so I am selling this one. I highly recommend this webcam to anyone who wants to record high-resolution video. However, if you intend to use Windows Hello facial recognition, I only recommend it to those with advanced PC skills and a PC with administrator privileges. Thank you.
