When a recording error occurs (e.g., data is missing) during playback, you can troubleshoot the cause by checking the
information in the event log and the Storage Server log file.
If you encounter problems when you use the Viewer, refer to the following solutions:

Solutions When Viewer Problems Occur
I cannot use the pan, tilt or zoom feature of the
camera in the video window. Double-click the video window or click [Control] on the [Camera Control] panel
If images are being played (the title bar of the video window is gray), you cannot
operate the camera. Click [Live] on the timeline and get control of the camera.
When I click a video window to display the
[Video Window] menu, [Record Now] is gray
(unavailable). But, I can use the feature in
another video window.Display [ Properties] for the video window and check on the
[Advanced] tab whether the camera is disabled. If the camera is disabled, click
[Enable Camera]. (p. 49).
When I try to use layouts created by other users,
the [Layout] menu is not displayed. I cannot
select a layout.Layouts saved in the [User Layouts] folder cannot be seen by other users.
To allow all users to access layouts created by a user, the layouts must be created by
a user with administrator permissions and must be saved in the [Shared Layouts]
folder (p. 65).
The quality of images (live and recorded) in the
video window is low.Change the receive size and display size settings. Depending on the receive size
and display size, the image quality may decrease. For example, if video with a low
receive size is displayed on a large video window, the image quality will decrease.
You can adjust the quality for recorded images with the advanced recording settings.
None of the cameras will record. Is the network cable for the server properly connected?
Has there been a power failure?
Is “Do not Record” specified for a special day schedule?
If link lamps on the hub (switching hub) and on the network connector on the
server do not light, there may be a defect in the server’s cable, hub (switch), or
