Network [1..1] DNS Domain Name
DNS Domain Name is the default domain name suffix which is added to unqualified names.
Example: If the DNS Domain Name is "company.com" and the name to lookup is
"MyVideoSystem", this will result in the DNS lookup "MyVideoSystem.company.com".
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: String with a maximum of 64 characters.
Network 1 DNS Domain Name: ""
Example:
Network [1..1] DNS Server [1..3] Address
Define the network addresses for DNS servers. Up to 3 addresses may be specified. If the
network addresses are unknown, contact your administrator or Internet Service Provider.
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: A valid IPv4 address or IPv6 address.
Network 1 DNS Server 1 Address: ""
Example:
Network [1..1] QoS Mode
The QoS (Quality of Service) is a method which handles the priority of audio, video and data in
the network. The QoS settings must be supported by the infrastructure. Diffserv (Differentiated
Services) is a computer networking architecture that specifies a simple, scalable and coarse-
grained mechanism for classifying, managing network traffic and providing QoS priorities on
modern IP networks.
Requires user role: ADMIN
Value space: <Off/Diffserv>
Off: No QoS method is used.
Diffserv: When you set the QoS Mode to Diffserv, the Network QoS Diffserv Audio, Network
QoS Diffserv Video, Network QoS Diffserv Data, Network QoS Diffserv Signalling, Network
QoS Diffserv ICMPv6 and Network QoS Diffserv NTP settings are used to prioritize packets.
Network 1 QoS Mode: Diffserv

Introduction Web interface System settings System settings
Network [1..1] QoS Diffserv Audio
Note: This setting will only take effect if Network QoS Mode is set to Diffserv.
Define which priority Audio packets should have in the IP network.
The priority for the packets ranges from 0 to 63 - the higher the number, the higher the priority.
The recommended class for Audio is CS4, which equals the decimal value 32. If in doubt,
contact your network administrator.
The priority set here might be overridden when packets are leaving the network controlled by
the local network administrator.
Requires user role: ADMIN
Value space: <0..63>
Range: Select a value between 0 to 63 - the higher the number, the higher the priority. The
default value is 0 (best effort).
Network 1 QoS Diffserv Audio: 0
Example:
Network [1..1] QoS Diffserv Video
Note: This setting will only take effect if Network QoS Mode is set to Diffserv.
Define which priority Video packets should have in the IP network. The packets on the
presentation channel (shared content) are also in the Video packet category.
The priority for the packets ranges from 0 to 63 - the higher the number, the higher the priority.
The recommended class for Video is CS4, which equals the decimal value 32. If in doubt,
contact your network administrator.
The priority set here might be overridden when packets are leaving the network controlled by
the local network administrator.
Requires user role: ADMIN
Value space: <0..63>
Range: Select a value between 0 to 63 - the higher the number, the higher the priority. The
default value is 0 (best effort).
Network 1 QoS Diffserv Video: 0
