Troubleshooting
If Network Camera Recorder does not function
correctly, check the following:
Symptom Cause and solution
The image of the
Network Camera cannot
be displayed.
Confirm that the image of the
camera is displayed using the Web
browser. Then, set up Network
Camera Recorder using the data
registered for the Web browser
(page 25).
For monitoring via the Web browser,
refer to the User's Guide of the
Network Camera.
“NO CONNECTION”
appears even if the
camera is connected.
The communication may be affected
by network conditions or ambient
wave conditions (for a wireless
connection).
For details on wireless connection,
refer to the User's Guide of the
Network Camera.
The recording cannot be
located.
Try to change the time scale and
search again (page 18).
No sound is heard. • Click the audio mute button on the
main toolbar of the main window
to cancel audio muting (page 14).
• Click on the monitor window to
select it (to be framed in yellow).
Sound will not be heard if no
monitor window is selected.
•Adjust Mic Volume on the Audio
tab of the Camera Properties dialog
(page 27).
Poor monitoring sound Change the audio bit rate to a higher
value such as G.726 (40kbps)
(page 27).
Audio and video are not
synchronized.
It is possible that audio and video
data may not be synchronized. This
is not a failure.
Exported data cannot be
viewed on another
computer.
The codec used for export must be
installed on the computer.
No sound is heard
during playback of the
data exported to an AVI
file.
Audio data cannot be exported to the
AVI file.
Network Camera
Recorder operates
normally, but an error
message is displayed at
the bottom of the
window.
The display of the last error message
is held at the bottom of the window.
It will disappear by restarting
Network Camera Recorder.
The frame rate or the
image quality decreases
when the camera or the
computer is used with
wireless connection.
The wireless connection may
provide a lower communication
speed than that for the wired
connection, causing a lower frame
rate, image quality and audio quality.
Try to select a smaller image size or
select MPEG4 in the Camera
Properties dialog (page 25).
The camera properties
cannot be changed and
the following error
message appears:
“xxxx (camera name)
Unknown Flow
Controller
Administrator User
name and the Password
are incorrect. Please
check them.: Received
HTTP status code 401
Unauthorized.”
The error message appears when you
did not enter the user name and the
password of the Administrator
registered in the Network Camera in
the Camera tab of the Camera
Properties dialog. Correct the user
name and the password on
Administrator (page 26). For the
registration of Administrator on the
Network Camera, refer to the User’s
Guide of the Network Camera.
