Host Name Configuration, Network Traffic

AXIS 221 - System Options 33

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-ConfigureLink-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-negotiatewhich 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 information, please refer to the online help .
