Video¶
The Video pane allows the playback of centrally stored videos, which are linked via date-time stamp from the currently selected event.
Events with associated video are identified with a small play icon on the Event Listing tab. When you select an event on the Event Listing or Finding Listing tab, all videos associated with the relevant event are shown on the Video pane:
Tip
The Video pane can be undocked, resized and placed outside of the NEXUS application, on another monitor for example.
If you are experiencing degradation of video quality due to frame dropouts caused by insufficient bandwidth, then disable one or more channels.
Configuration¶
You can tell NEXUS IC where to look for videos by setting the Global Video Path and/or Temporary Video Path in your database properties settings (see Properties).
You can then parse the video files (see Parse Video) to store their properties in the database. You can further manage video files under (see Video…).
For more information, see Managing Videos.
