Webcam Overview
A webcam is a compact digital camera designed to capture video and images in real time and transmit them to a computer or over the internet. It has become an essential device for personal, professional, and commercial communication, enabling face-to-face interaction regardless of physical location. Webcams are widely used for video conferencing, online meetings, live streaming, remote learning, telemedicine, and social networking.
Modern webcams are available as built-in components in laptops, tablets, and smartphones, as well as external plug-and-play devices that connect via USB or wireless interfaces. They typically include a camera lens, image sensor, microphone, and supporting software that allows users to adjust settings such as resolution, brightness, focus, and frame rate.
