Possible Causes or Corrective Actions
The camera cannot be ac-
cessed 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 de-
vice uses the same setting for the network connection type
(speed/duplex).
The camera cannot be ac-
cessed via a host name.
Check that the host name and DNS server settings are cor-
rect.
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.

and/or slow updating of im-
ages.
If images are very complex, try limiting the number of clients
accessing the camera.
