Once your DVR records video, the next step is search for - and play back - specific events.
There are two methods available to play back files. Clicking on the
Playback arrow at the
far right of the Control Bar will begin playback of the day’s recordings. However, if you are
looking for files recorded on a different day, or want to find a specific recording, clicking on the
Search icon in the Main menu will open the Video Search window.

Video Search
The Video Search window provides a pair of
options to retrieve files for viewing.
The calendar will highlight the current date in
blue and will use red to highlight other days
that contain video recordings.
Clicking on Playback will cause the DVR to start playing back all the recorded files from that
day beginning with the earliest one recorded. If more than one camera has video, the multi-
channel views will show the playback from each camera in synch with the playback from
others.
You may also narrow your search by selecting the hours to search between as well as the
type of recording -
Regular or Alarm using the pull downs under the calendar. Additionally,
you may limit your search to only select cameras.
Once you’ve set your options, you may double-click on the date in the calendar or on the
Search button below it to reveal a list of video files in the right side portion of the window that
match your criteria. Each listing will show the starting and end times, the type of recording and
whether the file has been locked to prevent erasure. Only a limited number of files will appear
at a time. Click on
Prev. , Next , Last or First to navigate through the “pages” of files. Double-
click on the desired file to begin playback which will occur in a new window.
Playback Shortcut
Clicking on the arrow at the far right of the Control Bar will open the Playback window and the
system will begin playing the first video(s) recorded that day.
