Completely off topic: what would be the best way to physically disable the wifi capability of a device. Obviously you can disable in software, but I'm the paranoid sort, and would love a way of knowing that my IP web cam is not gonna be doing anything with that wifi antenna. Thinking maybe some kind of terminator or some other way of "absorbing" the signals.
Find and remove the antenna for wifi. If that's not possible, make an impromptu faraday cage around the body of the camera. It won't completely block the signals but it should reduce it significantly.
