What Is USB Camera?

A USB camera, also known as a USB webcam or simply a webcam, is a digital camera that connects to a computer via a Universal Serial Bus (USB) port. This type of camera is designed to capture video and still images, often for the purposes of video conferencing, live streaming, recording tutorials, or security monitoring.

USB cameras typically do not require additional hardware for installation, as most modern operating systems, like Windows, macOS, and Linux, have built-in support for USB cameras through the UVC (USB Video Class) standard.

When you connect a USB camera to your computer, it should be automatically detected and configured by the operating system. If the camera is not recognized, you might need to install specific drivers provided by the camera manufacturer. Once installed, the USB camera can be used with various applications such as Skype, Zoom, or any software that supports video input.

USB cameras come in different qualities and features, ranging from basic models suitable for occasional use to high-definition (HD) models with advanced features like autofocus, built-in microphones, and better low-light performance, which are more suitable for professional use. Some USB cameras also support USB On-The-Go (OTG) functionality, allowing them to connect to devices like smartphones or tablets that support this feature.
