I spotted this one, claims to be 1440P. Specs say auto-focus in product blurb, detailed specs say fixed focus, can manually-adjust.
Is it just a 1280x720 webcam with image-enhancement firmware? I can't tell.

4K is not 4MP.

4MP Security Cameras – 2592 x 1520 – 3,939,840 pixels
4K Security Cameras – 3840 x 2160 – 8,294,440 pixels

it claims to be 1440p, which is about 4 million pixels.

larry if you want a 4k webcam buy a canon m200 and an elgato or atomos capture dongle. even a really good dedicated webcam is going to have huge depth of field, not as good focus tracking (not really needed because the depth of field is so huge), and will be short on detail compared to even a 1080p stream from a, say, m50. bigger sensors and lenses matter.
