• A firewall mechanism might have been activated. Check the
setting of your system or ask your network administrator. To
access the camera from the Internet, you may need to change the
setting of the firewall.

The number of frames
transmitted are less than
the defined value.
• Congestion of the network or objects of the image may affect the
number of frames transmitted. The number of frames may be less
than the defined value when they are transmitted via a congested
network.
• The number of frames transmitted may become less when
multiple users are viewing the video stream.
• The network hub might be another reason for this problem,
especially when multiple camera video streams are viewed
simultaneously.
When the audit function is
activated, the video
streaming area becomes
black or the transmission
becomes slower.
• When you connect your PC to the camera, no sufficient
bandwidth is available to support more frames with the current
resolution of video streams. Reduce the resolution to
QCIF(176x144) or CIF (320x240) and deactivate the audio
function.
• The audio signal needs 32 to 64 kbps of your bandwidth. You can
deactivate the audio function to improve the image quality. Your
Internet service may have not sufficient bandwidth to support
audio transmission.
Images cannot be
transmitted via e-mail or
FTP.
