Webcams are video cameras that save real-time images and video to a computer or stream them over a network, often used for video calls over the Internet; still images can also be captured using standalone units that plug directly into computers via USB port. Some webcams include physical shutters that can be adjusted to cover the lens in order to prevent unintended image capture.

Most webcams feature fixed-focus lenses that cannot be manually adjusted; some models offer autofocus that automatically focuses on subjects in motion or stationary, with an FOV (field of view) typically spanning 60 to 90 degrees horizontally, vertically and diagonally – selecting such models can help eliminate background clutter and noise during video calls.

Some webcams feature microphones capable of picking up audio from speakers or the surrounding environment, while other models may require additional accessories to deliver clear audio quality. If your microphone on a webcam is misinterpreting your voice during video calls, Techjury provides some helpful suggestions to enhance audio quality and increase its clarity.

Students and professionals using webcams regularly for video conference calls should select an HDMI-compatible unit, so it can be directly connected to their monitor. Meanwhile, those wishing to record videos for YouTube or other streaming platforms will require one with a USB port compatible with their computer.
