AXIS 225FD - System Options
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 Images (see below).
New Server Time - Select your time zone from the
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 camera will obtain the time from an NTP server every 60 minutes. Specify the NTP server's IP address or host name.
•Set manually - this option allows you to manually set the time and date.
Note: Note that if using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Network > TCP/IP below.
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 Advanced File Naming & Date/Time Formats in the online help 
for information on how to create your own file formats.
Network - Basic TCP/IP Settings
IP Address Configuration
The AXIS 225FD 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 camera 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: • To receive notification whenever the camera’s IP address changes (via e.g. DHCP), configure the options for notification of IP address change. See Services below.
•If your DHCP server can update a DNS server, you can access the AXIS 225FD by host name which is always the same, regardless of the IP address.
Services
Enable ARP/Ping setting of IP address - The IP address can be set using the ARP/Ping method, which associates the unit's MAC address with an IP address. Uncheck this box to disable the service in order to prevent unintentional resetting of the IP address. For more information see Other methods of setting the IP address in the AXIS 225FD Installation Guide.
Notes: • The ARP/Ping service is automatically disabled 2 minutes after the unit is started, or as soon as an IP address is set.
• Pinging the unit will still be possible when this service is disabled.
