AXIS 231D+/232D+ - System Options

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 guar-

antee the same level of security as an official certificate.

• An official certificate issued by a CA (Certificate Authority). A CA issues and manages

security credentials and public keys for message encryption.

1. Click either Create self-signed certificate 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 which will be

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 preferred CA for information on where to send the

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

Date & Time

Current Server Time . displays the current date and time (24h clock). The time can be

displayed in 12h clock format in the Overlay Images (see below).

New Server Time . Select your time zone from the drop-down list and check the daylight

saving time changes, if desired.

From the Time Mode section, select the preferred method to use for setting the time:

• Synchronize with computer time - sets the time from the clock on your computer.

• Synchronize with NTP Server - the network camera will obtain the time from an NTP

server every 60 minutes. Specify the NTP server's IP address or host name.

Note: Note that if using a host name for the NTP server, a DNS server must be configured under TCP/IP settings.

See Network > Advanced TCP/IP Settings below.

• Set manually - this option allows you to manually set the time and date.
