6.7 CLEAN IMAGE
The DVR unit is capable of recording video using one of three different resolutions. When using the 720 x 480
resolution, two fields are mixed. Because of the timing gap between the two fields, according to the standardized
image rules, after image might occur to high speed moving images. The Digital Watchdog DVR unit allows you to
remove this by pressing the CLEAN IMAGE button.
The images below demonstrate the filtered screen.
6.8 DAYLIGHT SAVINGS TIME
Th
e DVR automatically adjusts for Daylight
Savings Time changes. When the hour “jumps
forward” no video is lost because an hour is simply
skipped. However when the hour “falls back” there
is a duplicated hour that under normal
circumstances would be recorded over. The Digital
Watchdog DVR actually records both hours and
allows you to select which hour to play if the need
arises.
To access the “lost hour”:
1 From the Search screen, select the Select Date button.
2 Select the date when Daylight Savings time “lost” an hour. An option appears which says “Daylight Savings
Time.”
3 To play back the “lost” hour, select the Daylight Savings option.
4 Select OK to confirm the date and begin playing the video using standard search features.
