AXIS 231D+/232D+ - System Options

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 sources from including the video stream

from the

AXIS 231D+/232D+ 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(;).

Notes:

• If the referrals feature is enabled and 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

For greater security, the AXIS 231D+/232D+ can be configured to use HTTPS (Hypertext

Transfer Protocol over SSL (Secure Socket Layer)). That is, all communication that would

otherwise go via HTTP will instead go via an encrypted HTTPS connection.

Certificate - to

use HTTPS for communication with the AXIS 231D+/232D+, a Certificate

must be created using one of the following methods:

• A self-signed certificate can be

created in the network camera, but this does not

guarantee the same level of security as an official certificate.

• An official certificate issued by a CA (Certificate Authorit

y). A CA issues and

manages security credentials and public keys for message encryption.

1. Click either Create self-signed certifica

te or Create Certificate Request and enter

the required information in the provided fields.

2. Click OK.

3. Create self-signed certificate generates and installs a certificate displayed under

Installed Certificate.

Create Certificate Request generates a PEM formatted request which you copy and

send to a CA for signing. When the signed certificate is returned, click Install signed

certificate... to install the certificate in the AXIS 231D+/232D+.

4. Set the HTTPS Connection Policy for the administrator, Operator and Viewer to

enable HTTPS connection (set to HTTP by default).

Please refer to the home page of your preferr

ed CA for information on where to send the

request. For more information, please refer to the online help files
