VK Troubleshooting • It may take time to perform various viewer configuration changes or storage server operations.(If you are using Windows XP/Vista) Situation Solutions It may take time to perform storage server operations or configuration changes such as camera or schedule registrations sent by the viewer. (P. 1-12 Cases) z Be sure to register no more than 10 camera servers for one storage server. z In case you do register more than 10 camera servers to one storage server, please use Windows Server 2003/2008. • Live video is no longer displayed. (If you are using Windows XP/Vista) Situation Solutions Video from all camera servers is no longer displayed. (P. 1-12 Processes) z Be sure to connect no more than 10 camera servers to one viewer. (If you are using Autoswitching, set the interval to 20 seconds or longer). z In case you do connect more than 10 camera servers to one viewer, please use Windows Server 2003/2008. • When a layout sequence is running in the Viewer, the Video Window suddenly goes black and video of the Camera Server cannot be displayed. Situation Solution When a layout sequence is running, the Video Window goes black and video of the Camera Server cannot be displayed. When many Camera Servers are placed in one layout and a layout sequence is run in a short time, system resources required for communication may run short. Reduce the number of Camera Servers to be displayed in a layout, or make the switching interval for layout sequences longer. • Viewer operation seems to slow down. Situation Solution Viewer operation slows down. The performance of a Viewer depends largely on CPU specifications and graphics specifications of the PC on which the Viewer is installed. When Viewer operation slows down, try to reduce the number of Camera Servers to be displayed or decrease a live frame rate. If the video quality of Camera Servers is set high or the resolution is set to VGA, processing may take a long time because the size of image data is large. In this case, review the video quality or video size in the Camera Server settings. Timeline • The Playback controls are inactive.
