Time Overlap
If the time and date have been reset to a time that is earlier than the existing recorded
video, then 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.
Figure D-1 Time Overlap
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,
you can use Go to the Date/Time. You are given a choice of overlapping time
segments. Select the segment you want to search.
Figure D-2 Time Overlap Segment Selection
If you want to search recorded video from four to five o'clock during the overlapping
time range using a search method 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 are 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
