AXIS P1353–E Network CameraSystem OptionsDomain name - Enter the domain(s) to search for the host name used by the Axis product. Multiple domains can be separated bysemicolons. The host name is always the first part of a fully qualified domain name, for example, myserver is the host name in thefully qualified domain name myserver.mycompany.com where mycompany.com is the domain name.Primary/Secondary DNS server - Enter the IP addresses of the primary and secondary DNS servers. The secondary DNS server isoptional and will be used if the primary is unavailable.NTP ConfigurationNTP (Network Time Protocol) is used to synchronize the clock times of devices in a network. The NTP settings are configured underSystem Options > Network > TCP/IP > Advanced.Select Obtain NTP server address via DHCP to use the NTP settings provided by the DHCP server.To make manual settings, select Use the following NTP server address and enter the host name or IP address of the NTP server.Host Name ConfigurationThe Axis product can be accessed using a host name instead of an IP address. The host name is usually the same as the assigned DNSname. The host name is configured under System Options > Network > TCP/IP > Advanced.Select Obtain host name via IPv4 DHCP to use host name provided by the DHCP server running on IPv4.Select Use the host name to set the host name manually.Select Enable dynamic DNS updates to dynamically update local DNS servers whenever the Axis product’s IP address changes.For more information, see the online help .Link-Local IPv4 AddressLink-Local Address is enabled by default and assigns the Axis product an additional IP address which can be used to accessthe product from other hosts on the same segment on the local network. The product can have a Link-Local IP and a staticor DHCP-supplied IP address at the same time.This function can be disabled under System Options > Network > TCP/IP > Advanced.HTTPThe HTTP port used by the Axis product can be changed under System Options > Network > TCP/IP > Advanced. In addition to thedefault setting, which is 80, any port in the range 1024–65535 can be used.HTTPSThe HTTPS port used by the Axis product can be changed under System Options > Network > TCP/IP > Advanced. In addition tothe default setting, which is 443, any port in the range 1024–65535 can be used.To enable HTTPS, go to System Options > Security > HTTPS. For more information, see HTTPS on page 49.NAT traversal (port mapping) for IPv4A network router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by forwardingnetwork traffic from the private network to the “outside”, that is, the Internet. Security on the private network (LAN) is increasedsince most routers are pre-configured to stop attempts to access the private network (LAN) from the public network (Internet).Use NAT traversal when the Axis product is located on an intranet (LAN) and you wish to make it available from the other (WAN) sideof a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router is forwarded tothe product.NAT traversal is configured under System Options > Network > TCP/IP > Advanced.54
