Error Message
Possible Cause
Occurs when other network devices recognize that the
network is down because the router or hub is powered off.
Normally, this cannot be recognized, therefore this error is
rarely reported.
The connection was aborted by the camera due to a camera
restart or other causes. This may occur when the camera is
restarted using the restart button on the configuration page
provided by the camera software. However, this rarely
occurs.
A timeout occurred in the TCP connection with the camera.
(This occurs when the camera is powered off.)
The camera rejected the TCP connection. (This occurs when
the port number is incorrect or another cause.)
Occurs when the camera is powered off. (Normally, 10060
occurs.)
There is no route for connecting to the camera. (This may
also occur when there is a failure in the network cable
connected to the computer or hub.)
There is a failure on the computer's network adapter.
The host name could not be resolved in the DNS.
The host name could not be resolved in the DNS.
Possible Cause
The user authentication for connecting to the camera is
incorrect.
A connection cannot be established due to an IP address
restriction on the camera. (This may also be returned by a
proxy server.)
Occurs when the HTTP server is running but the Storage
Server is not started. It may also occur during normal
operation if the camera is restarted.
Occurs when the camera is temporarily unable to process
requests due to server overload (excessive requests from
multiple clients), or an uncompleted start-up process on the
camera, or other reasons.
Possible Cause
A request timeout occurred. Indicates that the connection or
request transmission failed.
The URL is incorrect. (Normally, this does not occur,
however, it may occur when an attempt is made to connect
to an unsupported camera.)
The host name could not be resolved. (This error is
generated when a host name that is not registered in the
DNS is specified or when a problem occurred in
communication with the DNS itself.)
