Gateway: If the unit communicates with a host on another subnet, it will talk through a device
called a router which links the NVR subnet to other networks, the IP address of this router is called
a default gateway.
Primary DNS: This is the primary DNS server IP address for applications that are using domain
names. If you want to use other DNS addresses from other units sitting on another domain on the
internet you need to add the IP address of your domains DNS server. This is done in this Primary
DNS setting. Adding the primary DNS server just means that the unit can use DNS names that that
the primary DNS server can see. It should be noted that DNS works hierarchically, such that firstly
any DNS enabled product will look at it local hosts.ini entries first. If it cannot find any reference
there it looks in the DNS mapping in its primary DNS server and if it is not there this will be
referred out further.
Max Transmission Rate (kbits/s): Allows you to set the maximum transmission speed for the
network type, consult the network administrator if necessary.
Tx Image Buffers: This is used in order to improve the picture delivery over Ethernet, use 1 for a low
bandwidth connection, and 3 for a higher bandwidth. This limits the amount of frame buffering in
transmission between NVR and client. This is used in order to improve the picture delivery over
Ethernet when using a slow connection, i.e. 256Kbps. Options available are 1, 2 or 3 buffers.
Ethernet MTU Bytes: The MTU is the largest physical packet size measured in bytes that the
network can transmit, default is set at 1500bytes. This is the maximum transmission unit (MTU) in
bytes of the largest packet that can be passed through the network interface. Typically, 1500 is a
good default for most networks, speak to your network administrator if this needs to be matched
to suit your network topology.
