AXIS 247S - System Options
24
The AXIS network video device presents its certificate to the network switch, which in turn forwards this to the
RADIUS server. The RADIUS server validates or rejects the certificate and responds to the switch, and sends its
own certificate to the client for validation. The switch then allows or denies network access accordingly, on a
preconfigured port.
RADIUS
RADIUS (Remote Authentication Dial In User Service) is an AAA (Authentication, Authorization and
Accounting) protocol for applications such as network access or IP mobility. It is intended to work in both
local and roaming situations.
CA servers
In cryptography, a Certification Authority (CA) is an entity that provides signed digital certificates for use by
other parties, and thus acts a trusted third party.
There are many commercial CA’s that charge for their services. Institutions and governments may have their
own CA, and there are free CA’s available.
Date & Time
Current Server Time - displays the current date and time (24h clock). The time can be displayed in 12h clock
format in overlay images.
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 Video Server 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.
Date & Time Format Used in Images - specify the formats for the date and time (12h or 24h) displayed in the
Live View video streams.
Use the predefined formats or use your own custom date and time formats. See File Naming & Date/Time
Formats in the online help
for information on how to create your own file formats.
Network - Basic TCP/IP Settings
Your Axis Video Server supports both IP version 4 and IP version 6. Both versions may be enabled
simultaneously, and at least one version must always be enabled.
When using IPv4, the IP address can be set automatically via DHCP, or a static IP address can be set manually.
If IPv6 is enabled, your video server will receive an IP address according to the configuration in the network
router.
There are also options for setting up notification of changes in the IP address, and for using the AXIS Internet
Dynamic DNS Service. For more information on setting the IP address, please see the online help.
Notes:
•DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may lead to the
situation where the IP address changes and you lose contact with the video server. Configure the options for notifica-
tion of IP address change (under Services) to receive notification from the video server when the IP address changes.
•Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 247S by host name which is always
the same, regardless of the IP address.
