AXIS 221 - System Options
Host Name Configuration
The camera 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.
Enable dynamic DNS updates - The camera includes support for dynamically updating
local DNS servers whenever the product's IP address changes. Check this box to enable the
function.
Note that these settings concern the use of local DNS servers and should not be confused with the settings
for the Axis Internet Dynamic DNS service.
Register DNS name - The name entered here will be associated with the camera's IP
address in the DNS server. An example of a DNS name is Axisproduct.example.com
TTL (Time To Live) - This value determines how long (in seconds) the reply from the DNS
server should be remembered by clients when they check that the domain name for the
registered IP address is still valid. This reduces the number of times the client needs to
query the DNS server, which in turn reduces network usage.
Link-Local Address
Auto-Configure Link-Local Address is enabled by default and assigns the camera an
additional IP address for use with the UPnP protocol. The camera can have both a
Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not affect
each other. See
Network - UPnP, on page 34.
HTTP
The default HTTP port number (port 80) can be changed to any port within the range
1024-65535. This is useful for e.g. simple security port mapping.
Network Traffic
The default setting is Auto-negotiate which means that the correct speed is automatically
selected. If necessary, the connection speed can be set by selecting it from the drop-down
list.
Maximum bandwidth - Specify, in Mbit/s or Kbit/s, the maximum bandwidth that the
camera is allowed to use on the network. This is a useful function when connecting the
camera to busy or heavily loaded networks. The default setting is Unlimited. For more
