Most webcams have a USB cable attached to them. Plug that cable into an available USB port on your laptop or desktop computer. All recent operating systems, including Windows, macOS and most Linux distros, will recognize the webcam out-of-the-box. Generic drivers are almost always pre-installed, but some high-end webcams may ship with custom software for better results. In that case, go to the webcam manufacturer’s website and download the drivers and custom configuration software.
