Problem
Some cameras do not record.
I cannot connect to the Storage Server from the
Viewer.
I cannot view live images.
The Storage Server slows down or it takes longer
to perform various configuration changes, such
as registering cameras or recording schedules
from the Viewer. (for Windows Vista)
Live images are no longer displayed from any
camera. (for Windows Vista)
When the layout sequence feature is used, the
video windows suddenly go blank and the
image from the cameras can no longer be
displayed.
The Viewer slows down.
• Is the power and the network connection for the cameras working?
• Do the cameras reply to a ping?
• Can you view live images on the Viewer for the cameras?
• Is "Do not Record" specified for a special day schedule?
• Is sensor recording or motion detection recording set?
• Are the login user name and password correct?
• Is the network connection between the server and the Viewer working?
• Is the IP address of the destination server correct?
• Does the server reply to a ping from the Viewer computer?
• Is TCP port 80 being used by another application?
• If "Could not connect to camera" is displayed in the video window, check the
camera's power supply and network connection.
• If a message is displayed in the timeline of the Viewer indicating that an error
occurred when connecting to the camera, check the camera's power supply and
network connection.
• If the screen goes blank when the layout is switched, but a video is displayed after
a few seconds, the number of cameras or the live frame rate setting exceeds the
performance capabilities of your computer. Reduce the number of cameras, or
decrease the frame rate.
• Make sure that less than 10 cameras are registered on each Storage Server.
• If the Storage Server is running Windows Vista, use Windows Server 2008 instead.
• Make sure that less than 10 cameras are connected to one Viewer.
• If you are using the layout sequence feature, set the interval to 20 seconds or
longer.
• If the Storage Server is running on Windows Vista, switch to Windows Server 2008.
When you use the layout sequence feature to switch quickly to a layout where there
are a large number of video windows, the communication resources of the system
may become insufficient. Reduce the number of cameras in a layout, or make the
display interval for the layout sequence longer.
• The performance of the Viewer depends largely on the specification of your CPU
and graphics card. When the Viewer seems to slow down, try to reduce the
number of cameras in the Viewer or decrease the frame rate.
• If the video size or quality setting for the cameras is high, the large amount of
image data may cause processing to take longer. Try adjusting the video quality
and video size settings on the camera.
