Up until now, most people have believed that the LED indicator which sits next to the webcam of laptop and desktop computers provides some warning that the device has been activated.
A webcam is a video camera that feeds or streams its image in real time to or through a computer to a computer network.
When "captured" by the computer, the video stream may be saved, viewed or sent on to other networks via systems such as the internet, and emailed as an attachment.
When sent to a remote location, the video stream may be saved, viewed or on sent there.
