AXIS Q19 Series - System Options

Use the following DNS server address - Enter the desired DNS server by specifying the following:

• Domain name - Enter the domain(s) to search for the host name used by the network camera. 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 ser

vers - Enter the IP addresses of the primary, and secondary DNS servers.

Note: This is not mandatory with regard to 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 creat

e manual settings, check this radio button and enter the host name or IP

address of the NTP server.

Host Name Configuration

The network 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.

Link-Local IPv4 Address

This is enabled by default and assigns the network camera an

additional IP address for use with UPnP™. 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.

HTTP and HTTPS

The default HTTP/HTTPS port numbers (80 and 443 respectively) can be changed

to any port within the range 1024-65535.

This is useful for simple security port mapping, for example.

NAT traversal (port mapping) for IPv4

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”, that is, the Internet. Security on the private network

(LAN) is increased since most broadband routers are pre-configured to stop attempts to access the private network (LAN) from

the public network/Internet.

Use NA

T traversal when your network camera 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 camera.

Notes:

• For NAT traversal to work, this must be supported by the broadband router.The router must also support UPnP™.

• 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.

Enable/Disable - When ena

bled, the network camera attempts to configure port mapping in a NAT router on your network,

using UPnP™. Note that UPnP™ must be enabled in the camera (see System Options > Network > UPnP).
