Webcams allow online video communication, online video chat and live streaming. They are a very useful tool in video conferencing, but also can be used for home and office chatting, online education, security and more. Many laptops come with a built-in webcam, and external webcams are available for desktops as well as tablets. In recent years, webcam quality has improved significantly, and a wide range of features are available.
Streaming webcams see use in the corporate world for video conferencing, enabling remote or at home employees to attend company meetings from any location with an Internet connection. They are also a handy tool for business owners who want to provide the public with an inside view of their company, service or event. Streaming webcams are even used by individuals who want to keep an eye on their children or pets from far away.
While the line between cameras and webcams has become increasingly blurred, there are still distinct differences in quality and capabilities. The most basic webcams offer 320×240 pixels resolution, and the highest quality models feature up to 4K. Higher resolutions are useful for professionals who want to edit their footage or for those who need to use green screen technology.
Other common webcam features include autofocus, which helps the camera focus on the subject in frame. The field of view (FOV) is also important, and webcams can feature up to 360deg horizontal FOV for an entire room. Some webcams have noise reduction, which reduces the background noise in recorded videos. online webcams
