External camera is not recognized

I want to use a camera to record videos with my laptop because the camera records at a huge resolution, and doesn't have as much storage as my computer. My laptop recognizes it as a storage device, but not as a camera.

Might be related, although I'm not sure, but I have an integrated camera, and Kamoso recognizes it as it was 4 webcams (all named "integrated"): all of them show the same thing, although 1 and 3 show the images in gray scale.

This list is the same with and without the external camera. Iriun Webcam is the integrated camera. I don't know why they appear separately.
