Webcams, short for web cameras, are small digital camera devices that connect to a computer. They enable you to communicate across the internet via video. Webcams can also take still digital photographs. Most webcams feature a built-in mic for voice capture. Therefore they are ideal for video calling, for example on Skype. Webcams are popular for video conferencing, security camera surveillance, social media video recording or just keeping in touch with people across the world. Additional webcam features include motion sensing or image recording.
