Webcams are common tools for communication, remote work, education, and content creation. At their simplest they convert optical images into digital streams, but modern webcams also integrate microphones, on-board processing, and a range of software features that affect video and audio quality. Understanding how a webcam works, what to expect from built-in microphones, and how technology influences performance can help you choose the right setup and get better results on calls, recordings, and broadcasts.
