webcam

A webcam, short for "web camera," is a small camera that sends video to a computer or over the internet. People mainly use it for video calls, online meetings, and live streaming. It lets others see you in real time, which makes it useful for work, school, and everyday conversations.

Many laptops come with one built in, while others use an external one for better picture quality, sound, or camera angle. People also use it to record videos, stream games, or watch a room, a pet, or a doorway from far away.

The word "webcam" usually means a small digital camera used with a computer or similar device to send live video. In most cases, people think of it as the camera used for video calls, online classes, work meetings, and live streams. Some are built into laptops, tablets, or monitors, while others are separate devices that connect by USB or wirelessly.

People use webcams in many everyday situations. A student may turn one on for an online lesson. A worker may use one during a meeting on Zoom or Microsoft Teams. A content creator may use one to stream on Twitch, record a reaction video, or talk to an audience on YouTube. Friends and family also use webcams to see each other during long-distance calls.

The word can also cover cameras used to watch a place from a distance, such as a room, an office, a front door, or a pet at home, especially when the camera sends a live picture through an app or website. In that wider sense, a webcam is not only for conversation but also for remote viewing and simple monitoring.

Quality can vary a lot. Built-in models are convenient, but external ones may offer sharper video, better low-light performance, a wider view, autofocus, or a built-in microphone. In everyday English, the word usually suggests a practical, easy-to-use camera for live video rather than a camera made mainly for high-end filmmaking or photography.
