That seems overall sensible to me. I don't have any cameras* in the rooms I stay/work/sleep, and made sure that things like microphones are really only active when I want them to (eg. the mic line on my VoIP phone is hard-wired to the big, red indicator light on it). I feel very uncomfortable when I feel watched/listened to, and with digital devices there is no easy way to discern "could watch/listen" and "does watch/listen", so restrictions need to be placed in the real world, not in the world of bits and bytes...

* Actually I do have one-or-the-other (D)SLR, but these are "dumb", not networked, and can positively not take pictures without somebody noticing - clack.
