I am selling this item because I purchased it new but rarely had the opportunity to use it. The "GV-HUVC/4K" is a capture device that allows you to easily import HDMI output video to your computer. It supports UVC (USB Video Class), and devices such as single-lens reflex cameras and video cameras connected to this product with an HDMI cable are recognized as "camera devices" on Windows and Mac, allowing them to be used like webcams. It also supports recording and streaming at up to 4K/30p. Single-lens reflex cameras and video cameras offer higher quality audio and video than typical webcams, and they also provide greater flexibility, making them useful for real-time streaming of the video you want to convey. To reduce shipping costs, I will ship only the contents, not the box. Therefore, I am offering it at a bargain price. Please check the manufacturer's website for more details. https://www.iodata.jp/product/av/capture/gv-huvc4k/ Color: Black
