12.3 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
,
Text-In
Search
or
Motion 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
