Searching through Archive
DW Spectrum provides many features that make archive search faster, more convenient and intuitive. Since archive
may contain significant video data (taken over several months), it is crucial to minimize the time spent by a user on
searching a particular event.
The following search methods are introduced:
 Calendar – pan temporal time line can zoom in on selected date to make search easier (see "Using Calendar").
 Smart Motion Search – select a region on video and allow for the application to automatically refine the archive
and highlight the fragments that involved motion. See "Performing Smart Motion Search".
 Thumbnail Navigation – small previews are displayed on top of the Time Line to help locate a particular scene. See
"Using Thumbnails for Better Navigation".
 Preview Search – select a region and allow for the application to provide videos that represent a time period based
on time stamps. See "Preview Search".
 Bookmarks – It is possible to select a part from a single Camera footage and give it a name, description and assign
tags. This makes the search much easier. See "Using Bookmarks".
Finally
Using Calendar
This type of search helps the user to locate an event that took place on a particular date and time.
To perform a calendar search:
1. Open Camera that contains the archived event.
2. Press CLND. Calendar will appear above Time Line. The dates that are displayed on Time Line are highlighted in
green:
It is possible to pin Calendar if needed
3. Select a desired date in Calendar. To select multiple dates , use CTRL. Time Line zoom will automatically change to
reflect the selected date(s) only. If the archive contains data outside the visible range, it will appear in shaded
green:
