The authentication process
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 the Overlay (see below).
New Server Time - Select y
our time zone from the drop-down list. If you want the server clock to automatically
adjust for daylight savings time, select Automatically adjust for daylight saving time changes.
From the Time Mode sec
tion, 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 camera will obtain the time from an NTP server every 60 minutes.
• Set manually - this option allows you to manually set the time and date.
Note:
If using a host name for the NTP server, a DNS server must be configured under TCP/IP settings.

1. A CA server provides the required signed certificates.
2. The Axis video device requests access to the protected network at the network switch. The switch forwards
the video device’s CA certificate to the RADIUS server, which then replies to the switch.
3. The switch forwards the RADIUS server’s CA certificate to the video device, which also replies to the
switch.
4. The switch keeps track of all responses to the validation requests. If all certificates are validated, the Axis
video device is allowed access to the protected network via a pre-configured port.
