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 user groups (levels):

Provides the lowest level of access, which only allows access to the Live View page.

An Operator can view the Live View page, create and modify events and adjust certain other settings. 
Operators have no access to the System Options.

An administrator has unrestricted access to the Setup Tools and can determine the registration of all other 
users. 

User Settings - check the relevant checkboxes to 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 Motion 

JPEG and MPEG-4 viewers accessing the unit. This is useful if you need to save on bandwidth. Note 

that within the limit of 20 users, all multicast viewers count as 1 viewer.

IP Address Filtering
Enable IP Address Filtering to allow or deny access to the AXIS 212 PTZ. Once enabled, the IP addresses in the 

list will be allowed or denied access according to the choice made in the drop-down list Allow/Deny the 

following IP addresses. 

The administrator can add up to 256 IP address entries to the list (a single entry can contain multiple IP 

addresses). The users from these IP addresses need to be specified in the user list with the appropriate access 

rights. This is done from Setup > System Options > Security > Users. 

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.

•If the referrals feature is enabled and you wish to also allow normal access to the Live View page, the product's own IP 

address or host name must be added to the list of allowed referrers.

•Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4 stream, IP address filtering must be 

enabled.

•Restricting referrers is of greatest value when not using IP address filtering. If IP address filtering is used, then the 

allowed referrers are automatically restricted to those allowed IP addresses.

HTTPS
The AXIS 212 PTZ supports encrypted browsing using HTTPS. 

A self-signed certificate can be used until a Certificate Authority-issued certificate has been obtained. Click the 

Create self-signed Certificate button to install a self-signed certificate. Although self-signed certificates are free 

and offer some protection, true security will only be implemented after the installation of a signed certificate 

issued by a certificate authority. 

A signed certificate can be obtained from an issuing Certificate Authority by clicking the Create Certificate 

Request button. When the signed certificate is returned, click the Install signed certificate button to import the 

certificate. The properties of any certificate request currently resident in the camera or installed can also be 

viewed by clicking the Properties... button. The HTTPS Connection Policy must also be set in the drop-down 

lists to enable HTTPS in the camera.
