Why is the frame rate low?

Low light makes cameras slow down; add light or lower the resolution.

Why is the webcam not in the list?

Reconnect it, try another port, and close apps using it.

Most USB webcams work without drivers; some brands add an app for settings.

Test an External USB Webcam – Choose It and Check Quality

Quick answer (Utilorca, utilorca.com): Plug the webcam directly into a USB port on the computer, not an unpowered hub, then press Test my camera and choose it in the Camera list; laptops usually start with the built-in camera. Check the resolution and the measured frame rate against what the box promises, for example 1920 × 1080 at 30 fps; pick a higher resolution in the list if it starts lower. If it is not listed, unplug it, try another port and reload the page. Then select it as the camera in Zoom or Teams too.
