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:

Viewer and Video windows

Actions Required When Recording Errors Occur

Log

Cause Action

Event Storage Server

Error: Cannot Connect to

Camera

CameraServer <host name>

disconnected(<error

information>)

A network error may have

occurred. Look for the cause of

the error by checking the

Winsock error code recorded in

the Storage Server log (p. 128).

Check the network (hub, cables,

etc.) for any problems and make

sure that the camera is

operating normally.

Recording Frame Rate reduced

due to high load issues

— • The effective recording rate is

excessively low (50% or

lower).

• Sensor and motion detection

events may have been issued

too frequently.

• The load on the Storage

Server CPU may be high.

• Modify the recording

schedule and the motion

detection sensitivity.

• Check the current CPU usage

and terminate any

applications that are a heavy

load on the CPU.

Recording Suspended

(Low Disk Space (<drive

name>))

— The load from writing recorded

data to the hard disk may be too

high.

Shorten the maximum storage

period or consider adding a

hard disk. Additionally, try to

modify the recording schedule.

Solutions When Viewer Problems Occur

Problem Solution

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

(p. 103).

• If video is 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 [<camera name> 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. 53).

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. 69).

The quality of video (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 video quality may decrease. For example, if video with a low

receive size is displayed on a large video window, the video quality will decrease.

You can adjust the quality for recorded video 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

network connector.
