After installing Security Center using
default security settings, cameras that do not support digest access authentication might
not work. To fix this issue, you can reactivate basic access authentication by video unit or
by manufacturer.
What you should know
Digest access authentication is the authentication scheme that most recent
video unit models support. This authentication scheme is more secure than
basic access authentication because the passwords are hashed
before sending them over the network. For this reason, basic access authentication is
disabled by default. After installation, if you realize that some of your cameras do not
support digest access authentication, you can revert them to basic access authentication
in Config Tool.
For added security, Security Center remembers whether or not a
specific video unit supports the digest authentication scheme. You can see the
authentication scheme used for each camera in the
Hardware
inventory report.
NOTE: After the
system has successfully authenticated to a video unit using the digest scheme,
you cannot revert to the less secure basic scheme.
Procedure
To reactivate basic authentication on a specific video unit:
-
From Config Tool, open the
Hardware inventory task.
-
Run the report on the video units that are inactive (in red) in your
system.
You might need to scroll horizontally to the right to see the
Authentication scheme column.
-
In the report pane, select the video units that are inactive and click
Reset authentication scheme.
The Authentication scheme changes to
Anonymous. After the Archiver successfully connects
to the video unit, the exact authentication scheme is displayed.
To reactivate basic authentication for a specific
manufacturer:
-
From Config Tool, open the
Video task.
-
Select the Archiver role that controls your cameras and click
Extensions.
-
Select the manufacturer that you want and set Refuse basic
authentication to OFF.
-
Click Apply.
