Why don't you, I don't know, unplug them when their not in use? I don't see how anyone could hack into them then. Are they such a problem to set up?
No but Vid Camera and Digital Camera aren't plugged in my comp o.O" Just laying on my desk xD When a Lens focusses on me I always turn it around for some reason o.O" Even when my Webcam isn't evven plugged in I turn it around >_>
