The camera can operate
only in the LAN rather in
the Internet environment. • 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.
• Make sure that your camera does not conflict with other servers
on the same LAN.
• Check the router and make sure that its setting allows it to access
your camera from the Internet.
The number of frames
transmitted is 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 QQVGA
(176x144) or QVGA (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. • Make sure the IP address of the gateway and domain server
(DNS) has been defined correctly.
• Where FTP still fails, contact your ISP or network administrator
to check the FTP server.
Camera Image Quality
Camera has a problem
focusing. • The lens might be contaminated with dust, fingerprints, or other
dirt. Use a special cleaning cloth to clean the lens or adjust the
focus manually.
• Focusing might be impossible in some cases. If the object is too
close to the lens, more it away from your camera.
Color of the video stream
is too deep or light. • Please confirm that the image you are watching has the best
quality. Adjust the setting of your display card (color quality) to
at least 16 bits (24 bits or more are recommended).
• Incorrect camera video setting. You may need to adjust some
parameters, such as brightness, contrast, color, and saturation.
Video stream flashes. • Incorrect power cord frequency may cause flashing of the image.
Confirm that your camera uses NTSC or PAL system.
• The image flashes if the objects are black. In this case, adjust the
illumination brighter around your camera.
