Comments: Probable event, but ca 40 sec late, Only D recorded.. Expected Time error 5 sec.  So 40 sec = 8 x error. D at last frame recorded, R during time OccuRec was closing down so not seen.  Had reappeared when diplay returned.  Duration unknown Scheduled video recording for 40 sec either side of event time.  I should have used a longer time range.
