Anyway I'm not bothered about time skipping, it's a chinese hardware
I accept it could be the camera and not frozen time, I just find it odd that when the 10th second arrives, it should be dark, but fine, I concede, it's just a bug...
But that leaves the unidentifiable light and the unidentifiable sound when there was no power coming into the complex to make any light or sound, if not for the battery, we wouldn't have seen anything
Again, you have confirmed yourself that this:
is an actual light from another building, and it momentarily turned on after the outage.
