AXIS 223M - System Options 43
NTP Configuration
Obtain NTP server address via DHCP - check this option to automatically look up and use the NTP server settings as provided by DHCP. Click the View button to see the current settings.
Use the following NTP server address - to make manual settings, check this radio button and enter the host name or IP address of the NTP server.
Host Name Configuration
The AXIS 223M can be accessed using a host name, instead of an IP address. The host name is usually the same as the assigned DNS Name. It is always the first part of a Fully Qualified Domain Name and is always one word, with no period. For example, myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com.
Enabling dynamic DNS updates allows you to alias a dynamic IP address to a static host name, allowing your computer to be more easily accessed from various locations on the Internet. Outside users can always access your server using the associated DNS name regardless of the WAN IP. The DNS server used by the user and/or the DNS server responsible for the domain in use must support RFC2136 and allow updates from the camera.
The TTL (Time To Live) value determines how long (in seconds) the reply from the DNS server should be remembered for when checking that the domain name for the registered IP address is still valid.
Link-Local IPv4 Address
HTTP
The default HTTP port number (80) can be changed to any port within the range
HTTPS
The default HTTPS port number (443) can be changed to any port within the range
NAT Traversal (port mapping for IPv4)
Use NAT traversal when your AXIS 223M is located on an intranet (LAN) and you wish to make it available from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router will be forwarded to the network camera.
