If you cannot view live video in Security
                                    Desk, you can troubleshoot the
      issue.
      Before you begin
         Ensure that you have access to Security
                                    Desk and Config
                                    Tool to perform the following
         steps.
      What you should know
         There are several possible causes for a missing signal error:
               - The network is slow.
- Port connection has issues.
- The video stream was dropped while it was being redirected to Security
                                    Desk.
To troubleshoot why you cannot view live video:
- 
            Wait to see if the camera connects.
         
- 
            If the problem persists for more than 10 seconds, click Show diagnosis in the tile, or press
                  Ctrl+Shift+D.
             Information about the video stream is displayed. The current step is
               highlighted:   
 - Initializing:    - The media player is preparing the required resources to display the video
                        stream. 
- Connecting to Media Router:    - The media player is establishing connection with the Media Router to obtain
                        the network location of the stream. 
- Connecting to Archiver and redirector:    - The media player is establishing connection with the Archiver and the
                        Redirector to request video. 
- Requesting live stream:    - The connection is established between the Archiver and the Media Player.
                        The Media Player is now requesting the live stream. 
- Analyzing the stream:    - The stream was requested and received by the client workstation. The media
                        player analyzes the stream to detect the video format and the presence of
                        key frames. After the stream is validated, the video is decoded.

                        - If you can view video, it might be a problem with the redirection from
                           the Media Router to your Security
                                    Desk. Continue with the
