A Fort McMurray family had a Canary system, apparently, and so they were able to watch their home burn down in real time on their phones. The fire comes in through the window at the left.
There’s audio. You can hear the glass breaking, and, eventually (but far too late), the smoke detectors going off around the time visibility becomes 0. The video continues after you have no more meaningful visuals, but given that audio continues the whole time I’m not sure if this is because the smoke was too thick, or because the video element perished ahead of the rest of the device.
In any case: Eeek.
