The question asked was whether the experts concealed their webcam when it was not in use.
Although many web cameras offer a telltale LED light which indicates whether it is active, Fairfax found many security experts didn't trust that it would operate correctly if a hacker compromised their machine. After all, hackers have found ways to disable some webcam lights.
A number of manufacturers, like Apple in their MacBooks and iMacs, ensure that the web camera is hard-wired in such a way that the green LED will always turn on regardless of any software changes. But some manufacturers don't make use of a light at all, or when they do they are very lax with how it is implemented, allowing for it to be easily turned off by software.

Information security analyst and Risky.biz podcaster Patrick Gray also admitted to covering up his laptop's camera. When he smoked, he used the glued part of a cigarette paper to protect it.
