Time Overlap
If the DVR’s time and date have been reset to a time that is earlier than the existing recorded video, it is possible for
the DVR to have more than one video stream in the same time range. In this case, you can search overlapping video
streams individually by selecting a specific segment. For example, when the DVR has recorded video from one to five
o’clock and the user changes the time backward from five to three o’clock and then continues recording until six o’clock,
there will be two video streams and segments from three to five o’clock.
You can search overlapping video streams by selecting a specific time or time range. If you want to search recorded
video at four o’clock during the overlapping time range using a search menu such as Go to the Date/Time, select the
segment you want to search.
If you want to search recorded video from four to five o’clock during the overlapping time range using a search menu
such as Event Log Search or Calendar Search, it is possible for the DVR to have two overlapping start and stop
times. You will be asked to select one of the overlapping start and stop times from the search time ranges as follows:
From four o’clock of the first segment to five o’clock of the first segment
From four o’clock of the first segment to five o’clock of the second segment
From four o’clock of the second segment to five o’clock of the second segment
