The expert advised to pay attention to whether the computer requires access to the camera and does not threaten to stop the operation of the device otherwise. Also, a lit indicator of the camera’s operation may indicate surveillance.
Even when the camera is hacked, applications that use it officially may be unstable. For example, Skype and Zoom. On the other hand, on a mobile device, a sign of surveillance can be a sharp increase in the volume of data transfer.
Researchers from the University of Saarland recently created a webcam in the shape of a human eye. The purpose of the development is to help people communicating on the webcam to establish an emotional connection, as when talking face to face. It’s worth noting that the eye camera looks pretty creepy.
