Personally, I no longer trust these established indicators. I now feel justified in assuming that backdoors are built into most systems and that Glass could be recording at any time, without my approval and without any indication.

It’s possible to wire the LED directly to the power of the camera. That way if the camera receives power the LED is also on. There is no way to change this behaviour in software. (This is how the indicator lights on Macs and presumably many other indicator lights are wired up.)

No, but it is comparatively easy to change this behaviour in hardware, so what's the point? Having an indicator that, "very often" works, is in some ways worse than not having an indicator at all...

[arrrg]

Uhhhh … how so?

Yeah, if someone has actual physical access to your device they might be able to detach the LED. Not easy to do – but imaginable. But that is hardly an in any way relevant scenario.
