Sure, button-cams have been used long the heyday of the private-citizen's cold-war, but damned if we've seen a consumer device marketed for self defense (i.e. Self Guard SG-210) that uses Bluetooth to move video around (presumably from the recorder to your PC) and records to SD. In fact, if your Self Guard is Internet-connected, you'll apparently even be able to view the video feed remotely.
