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.
No image using Refresh and/or
slow updating of images.
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.
Refocus the camera.
Poor image quality.
Increased lighting can often improve image quality. Check that there
is sufficient lighting at the monitored location. Check all image and
lighting settings.

Enable multicast checkbox is enabled in the System/Network/RTP
tab. Checks with your network administrator to see if there is a
firewall preventing viewing.
Multicast H.264 only accessible
by local clients.
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.
Color saturation is different in
H.264 and Motion JPEG.
Modify the settings for your graphics adapter. Please see the
adapter's documentation for more information.
Poor audio quality.
Too many users/clients connected to the camera may affect the
sound quality adversely. Try limiting the number of clients allowed to
connect.
