Possible Causes or Corrective Actions
If using a proxy server, try disabling the proxy setting in your
browser. Check all cabling and connectors.
Check if there are firewall settings that need to be adjusted.
Check if there are router settings that need to be configured.
If using a network switch, check that the port on that de-
vice uses the same setting for the network connection type
(speed/duplex).
Check that the host name and DNS server settings are cor-
rect.
When HTTPS is enabled, ensure that the correct protocol
(HTTP or HTTPS) is used. When attempting to log in, you
may need to manually type in http or https in the browser's
address bar.
If images are very complex, try limiting the number of clients
accessing the camera.
Check the Video & Image setting.
Refocus the camera.
Increased lighting can often improve image quality. Check
that there is sufficient lighting at the monitored location.
Check all image and lighting settings.
Try adjusting the Exposure Control setting under AE and
AWB part.
Check that the correct network interface is selected in the
Video & Image/Stream.
Check with your network administrator that the multicast
addresses used by the camera are valid for your network.
Check that the Enable multicast checkbox are enabled in
the System/Network/RTP tab. Checks with your network
administrator to see if there is a firewall preventing viewing.
Check if your router supports multicasting, or if the router
settings between the client and the server need to be con-
figured. The TTL value may need to be increased.
Modify the settings for your graphics adapter. Please see
the adapter's documentation for more information.
Check that the Micro-SD card is inserted properly.
