Problems/Symptoms
Possible Causes or Corrective Actions
The camera cannot be
accessed by some clients.
If using a proxy server, try disabling the proxy setting in your browser.
Check all cabling and connectors.
The camera works locally, but
not externally.
Check if there are firewall settings that need to be adjusted. Check if
there are router settings that need to be configured.
Poor or intermittent network
connection.
If using a network switch, check that the port on that device uses the
same setting for the network connection type (speed/duplex).
The camera cannot be
accessed via a host name.
Check that the host name and DNS server settings are correct.
Not possible to log in.
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.
Images only shown in black &
white.
Check the Video & Image setting.
Blurred images.
