If using a network switch, check that the port on that device
uses the same setting for the network connection type
(speed/duplex).

correct.
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 Camera
Setup part.
Check that the correct network interface is selected in the

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
configured. The TTL value may need to be increased.
