AXIS 212 PTZ/AXIS 212 PTZ-V- System Options
33
Domain name - enter the domain(s) to search for the host name used by the AXIS 212 PTZ/AXIS 212 PTZ-V.
Multiple domains can be separated by semicolons (;). The host name is always the first part of a Fully Qualified
Domain Name, for example, myserver is the host name in the Fully Qualified Domain Name
myserver.mycompany.com where mycompany.com is the Domain name.
DNS servers
- enter the IP addresses of the primary and secondary DNS servers.
NTP Configuration - Obtain NTP server address via DHCP - check this radio button 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 212 PTZ/AXIS 212 PTZ-V 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 when checking that the domain name for the registered IP address is still valid.
Link-Local IPv4 Address - Link-Local Address is enabled by default and assigns the AXIS 212 PTZ/AXIS 212
PTZ-V with an additional IP address for the UPnP protocol. The AXIS 212 PTZ/AXIS 212 PTZ-V can have both
a Link-Local IP and a static/DHCP IP address at the same time - these will not affect each other. See UPnP™, on
page 35.
HTTP - The default HTTP port number (80) can be changed to any port within the range 1024-65535. This is
useful for example, simple security port mapping.
HTTPS - The default HTTPS port number (443) can be changed to any port within the range 1024-65535. HTTPS
is used to provide encrypted web browsing.
NAT traversal (port mapping) - A broadband router allows devices on a private network (LAN) to share a single
connection to the Internet. This is done by forwarding network traffic from the private network to the “outside”
i.e. the Internet. Security on the private network (LAN) is increased since most broadband routers are
pre-configured to stop any attempts to access the private network (LAN) from the public network/Internet.
Use NAT traversal when
your AXIS 212 PTZ/AXIS 212 PTZ-V 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 camera.
Notes:
• For NAT traversal to work, this must also be supported by the broadband router.
• The broadband router has many different names: “NAT router”, “Network router“, Internet Gateway”, “Broadband sharing device” or
“Home firewall” but the essential purpose of the device is the same.
