Webcam

A digital video camera peripheral (or integrated component) that streams real-time video and audio data over a computer network, primarily the internet.

The Webcam is a compact digital camera designed for real-time data transmission: it captures video and audio, converts it to a digital format, and streams it via USB or wireless protocol. Its history began in 1991 with the famous Trojan Room Coffee Pot at Cambridge University. Today, webcams are essential for modern communication, powering platforms like Zoom and Microsoft Teams, enabling remote work, and facilitating the massive live-streaming industry on Twitch and YouTube. They are deployed across devices, from integrated laptop hardware to high-resolution 1080p external peripherals, and are also critical for security monitoring and surveillance systems.
