This is a BUFFALO HD720p webcam. I only tested it after purchasing it. It has been used very little and is in very clean condition. There are no noticeable scratches or stains. It's a built-in microphone model, and you can use it immediately by connecting it via USB. No drivers are needed (UVC compatible), so it's recommended for beginners. 【Main Features】 ・HD 720p (1280 x 720) support ・Effective pixels: 1.2 million pixels ・Up to 30fps ・Built-in microphone ・Manual focus ・16:9 wide screen support ・USB connection (approx. 1.5m) 【Supported OS】 Windows / Mac / PS3 compatible The outer box has been opened and has some minor scuffs, but there are no problems with the main unit. Please refrain from purchasing if you are sensitive to used items, as it has been stored at home. Instant purchase is OK.
