Beneath the camera and video information, you will notice a sunken horizontal bar. This is a
histogram. When motion detection information has been captured by a motion detection
enabled camera supported by the Buffalo Surveillance Server, the histogram indicates the
motion detection threshold was reached. It enables you to skip past sections of video in which
no motion was detected. When supported motion detection cameras are utilized, this bar is
populated with histogram information and will look something like this:
Line height and color indicate the magnitude of the motion detected (based on how your
motion detection enabled camera is configured). For information about how Buffalo Surveillance
Server automatically configures supported cameras, see the Customization Settings section
titled AXIS Camera Motion Detection Configuration.
When no motion has reached the detection threshold, the histogram will be empty. Where no
motion detection data has been gathered, whether because the camera does not support
motion detection or had a technical problem, the histogram will be filled with a black bar.
In the Search Results frame, click the thumbnail image for the file you want to view, or click a
point of interest in the histogram. Either of these actions will open the Media Viewer with the
original video file ready for playback and review.
The Media Viewer
The Media Viewer enables you to play back and review videos at variable speeds, search
metadata content, navigate to a particular point in a file, clip particular parts of videos for export,
and send clips to the Export Queue.
