All words are general-purpose, but when we arrange them they adopt new meaning. I'm not nitpicking, and just pointing out that the meaning of those words as arranged may not be perceived as the author originally intended. Alternatively, I'd suggest a different arrangement of words like "lens cover", "webcam cover", "webcam cover slider", or "webcam privacy shield" to be more accurate. Of course we were able to grock what "mechanical camera shutter" meant in this context, although at first I was confused and wondered if in fact there were webcams with mechanical focal plane or leaf shutters.
