I have four available, $60 each or $220 for all four. This webcam is pretty useful, it's like a USB GoPro in an industrial metal case. The image quality is similar to GoPro and Mokose UC40, which is known as one of the best 4K webcams. It has a 4K Sony IMX415 sensor, which is better than 95% of webcams on the market. The lens is a 2.8-12mm M12 mount 1/2.5 Inch "varifocal"/zoom lens that is 150-degree FoV fish eye at the wide end (AKA 2.8mm focal length) like a GoPro, and you can get a low distortion image around 6-12mm zoom. The M12 lens has a bit of fisheye but it's replicable and it's very bright. It has 4K MJPEG (i.e. a bunch of JPEG images) and an HDMI port that is 1080p only but can do YUY2 (means it has better colors than MJPEG).
