3.4.9. Preview Search
Users can search recorded video in split-screen mode by the hour or minute units.
The Thumbnail search breaks down a day’s worth of recorded video for a camera into 12 still
images, one for each hour. You can then “zoom” into the hour to display images for every
minute of that hour. To use Preview Search:
1. Right-click on the selected channel and go to Preview Search.
2. Select the date you wish to search. Days with recorded video will appear in orange.
3. Click SEARCH. The DVR will display 24 screen images (1-hour unit) of the channel on
that day.
4. Select a preview thumbnail and click the Minute button to display 60 screen images (1-
minute unit) on that hour.
Users can easily and instantly search large amounts of video for specific events with this
preview search, allowing you to playback the recorded image of that moment.
The number of thumbnail images and size of each image can be increased/decreased up to a
maximum 60 thumbnail images on a single screen.
In the preview search mode, the user can change the search date, the display unit (time/minute)
and go to playback mode directly.
