If the sensor is physically getting power, the light is too, unless the wire is broken. They are on the same circuit. It is not a firmware thing, its basics circuits Physics 101. The light could be burnt out, yes. The wire could break sure. But it can't be hacked (minus pulse modulation, not giving the light enough time to light up). But if you power up the camera, and something isn't physically broke... the light comes on. I know the privacy incident has already happened, separate argument. I think people are missing the hardwired point. This discussion should be focusing on the fact that if the camera has powered on, and we see it, it's already too late.
