exposure time is set to 1/30.
it flashes most of the time throughout the night, switches between the day/night modes, then it will change/flash again, etc.. video was taken late in the evening, the level of darkness is consistent (there is a street lamp on the opposite side of the street)..
another video (sorry for the shakiness/bluriness)
