AXIS 213 PTZ
31
NTP Configuration
The AXIS 213 PTZ can obtain the correct time from an NTP server. The address for the NTP server can
either be obtained via the DHCP server, or it can be entered manually.
Host Name Configuration
The AXIS 213 PTZ 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.
The enable 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 Address
Link-Local Address is enabled by default and assigns the AXIS 213 PTZ an additional IP address for the
UPnP protocol. The AXIS 213 PTZ can have both a Link-Local IP and a static/DHCP IP address at the same
time - these do not affect each other. See Network - UPnP, on page 32.
HTTP
The default HTTP port number (port 80) can be changed to any port within the range 1024-65535. This is
useful for simple security port mapping, for example.
NAT Traversal
Use NAT traversal when your AXIS 213 PTZ 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 is forwarded to the network camera.
Enable/Disable - when enabled, the AXIS 213 PTZ attempts to configure port mapping in a NAT router on
your network, using UPnP™.
Use manually selected NAT router - select this option to manually select a NAT router. Enter the IP address
for the router in the field provided.
If a router is not manually specified, the AXIS 213 PTZ Network Camera automatically searches for NAT
routers on your network. If more than one router is found, the default router is selected.
Alternative HTTP port - select this option to manually define an external HTTP port. Enter the port number
in the field provided. If no port is entered here a port number is automatically selected when NAT traversal
is enabled.
RTSP
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Enter the RTSP port number to
use. The default setting is 554.
Network Traffic
The default setting is Auto-negotiate which means that the correct speed is automatically selected. If
necessary, you can set the connection speed by selecting it from the drop-down list. 10BaseT (Half/Full
Duplex), 100BaseTX (Half/Full Duplex).
Maximum bandwidth - Specify, in Mbit/s or Kbit/s, the maximum bandwidth that the AXIS 213 PTZ is
allowed to use on your network. This is a useful function when connecting the AXIS 213 PTZ to busy or
heavily loaded networks. The default setting is Unlimited.
