sure that your Internet Explorer security is properly set (the default
value is moderate). Re-connect to the camera main page and
download the file again. Incomplete download or installation of the
camera ActiveX control is the major reason for this problem. Check
the security setting of your Internet Explorer. Close and re-open
Internet Explorer, and enter the main page to see if you can log in.
Internet Explorer displays
the following message:
Downloading the ActiveX
control is prohibited under
the current security
setting."
Change the IE security setting to allow downloading unsigned

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 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.
• Make sure the IP address of the gateway and domain server
(DNS) have been defined correctly.
• Where FTP still fails, contact your ISP or network administrator
to check the FTP server.
I can't control the camera
to move up, down, right,
left or to the center or
preset point.
• When communication to the camera stops, click
"Refresh"
on
your IE browser to refresh the transmission.
• It might be that other users are controlling the movement of the
camera.
• The horizontal/vertical movement of the camera has reached its
limit.
• The horizontal/vertical remote control option of the camera might
have been deselected.
