If you had quoted the sentence in full:
you had my answer. 
And yes, you’re right (I guess).
Of course I’m generalizing. And I’m not a sociologist and neither have I studies as proof. It’s just that everyone (but one) of my friends, family members, acquaintances doesn’t have a clue - and a majority thinks that taping the camera helps - like other rather doubtful things. There’s a nice comparison (which sadly lacks the taped camera):

It shows that there’s a stark difference in measures deemed effective between experts and most others. This doesn’t have to be a permanent state though. I really like to take part in changing that (though I’m no expert, which might prove that there’s hope).
Taping the camera is an expression, indicator or a metaphor for a much deeper lack of knowledge (and yes, it doesn’t hurt but really, it is useless). I take it as a hint that I might share some insights or solutions to problems that are hidden to many - and (I must insist) that there are far greater problems than someone spying on your camera.
