DST DATE/TIME SEARCH AND PLAYBACK

If the unit is configured for Daylight Saving Time (DST), the DVR uses a different approach to store and display video. When DST ends, the DVR’s internal time automatically adjusts backward one hour. Video is time-stamped and recorded one hour before and one hour after the time change. When DST begins, the DVR’s internal time automatically adjusts forward one hour and the unit records normally.

The Date/Time search feature allows you to view video recorded before and after a DST time change (refer to Figure 16). For example, the DVR is configured for DST to end at 2:00 a.m. on November 1, 2009. The time period between column 01 and column 02 for channel 1 represents two recording periods:

DST active (during DST): Video recorded between 1:00 a.m. to 2:00 a.m.

DST ended (after DST): Video recorded between 1:00 a.m. to 2:00 a.m.
