33 AXIS 221 - System Options
System Options
Security - Users
User access control is enabled by default. An administrator can set up other users, by
giving these user names and passwords. It is also possible to allow anonymous viewer
login, which means that anybody may access the Live View page, as described below:
Users - the user list displays the authorized users and access levels:
• Viewer - the lowest level of access, which only allows the user access to the Live
View page.
• Operator - an Operator can view the Live View page, create and modify event types
and adjust certain other settings. The Operator does not have access to the Systems
Options configuration pages.
• Administrator - an administrator has unrestricted access to the Setup Tools and can
determine the registration of all other users.
To add a new user, click the Add... button and see the online help.
User Settings - check the relevant checkboxes to enable:
• Enable anonymous viewer login - allows any viewer direct access to the Live View
page.
• Maximum number of simultaneous viewers - enter a value here to restrict the
number of unicast viewers accessing the unit. This is useful if you need to save on
bandwidth. (Note that all multicast viewers count as 1 viewer.)
Note:
The AXIS 221 keeps a log of all users that access it. See Logs & Reports, on page 44.
Security - IP Address Filtering
Checking the Enable IP address filtering box enables the IP address filtering function. Up
to 256 IP address entries may be specified (a single entry can contain multiple IP
addresses). Click the Add button to add new filtered addresses.
When the IP address filter is enabled, addresses added to the list are set as allowed or
denied addresses. All other IP addresses not in this list will then be allowed or denied
access accordingly, i.e. if the addresses in the list are allowed, then all others are denied
access, and vice versa. See also the online help for more information.
Referrals
To prevent unauthorized clients from including the video stream from the cameras into
external Web pages, check the Referrals checkbox and enter the IP address or Host name
of the computer that hosts the Web pages with the included video stream. Several IP
addresses/host names can be defined and are separated by semicolons (;). This option is
only applicable to Motion JPEG video streams.
