Webcam security question, what would it take for remote access?

The only thing i can tell you is...to prevent from possibly being spied on with your own webcam...just close the cover over the lens when no in use..and if you ever see the green light on when your walking around or working on the computer ...then you know your being watched...hackers and spy criminals are getting more and more sophisticated and know they have created a way to hack your Logitech webcam...and for that very reason...i uninstalled mine 2 months ago and will not use it again unless absolutely necessary....
