USB camera accessory made by Potensic. It didn't work with iPhone. It connected to Android. I haven't tested it on a PC, so I don't know, but since it connects to Android, I think it will connect to a Windows PC. There is no OS, so please install it. I remember it was free. I couldn't find the accessories, so it's just the main unit. I've only used it once, so I haven't confirmed the operation. Please consider it as junk.
