Code Error Message Possible Cause
401 Unauthorized The user name and password for connecting to the camera
is incorrect.
403 Forbidden A connection cannot be established due to an IP address
restriction on the camera. This may also be returned by a
proxy server.
500 Internal Server Error 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.
503 Service Unavailable 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.
Code Error Message Possible Cause
12002 The request has timed out. A request timeout occurred. Indicates that the connection or
request transmission failed.
12005 The URL is invalid. The URL is incorrect. Normally, this does not occur, however,
it may occur when an attempt is made to connect to an
unsupported camera.
12007 The server name could not be resolved. 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.
12017 The operation was canceled, usually because the handle on
which the request was operating was closed before the
operation completed. The communication was canceled. This error does not
indicate a problem and may be generated during normal
operation.
12029 The attempt to connect to the server failed. The connection to the camera failed. Normally 12002 is
generated.
12030 The connection with the server has been terminated. The connection to the camera has been aborted. The
disconnect process itself is recorded when it executes
normally.
12031 The connection with the server has been reset. The connection to the camera has been reset.
