Network: General

Network Access: Here you can choose between the three
different types of networks that the NVR can be connected to.
The three types of networks are:
DHCP: DHCP (Dynamic Host Configuration Protocol) is a
system where one device on your network (usually a router)
will automatically assign IP addresses to devices connected
to the network.
STATIC: Static networks require all devices to have their IP
addresses manually defined, as there is no device dedicated to
automatically assigning addresses.
PPPoE: An advanced protocol that allows the NVR to be more
directly connected via a DSL modem. This is an option for
advanced users only.
IP Address: Just as houses and businesses need to have an
address which identifies their location on the road network, so
too do computers and other devices need addresses (called
IP ADDRESSES) to identify their position on the electronic
network. The NVR uses IPv4 addressing, which consists of four
groups of numbers between 0 and 255, separated by periods.
For example, a typical IP address might be "192.168.1.24" or
something similar. The most important thing when setting the
IP address is that nothing else on your network shares that IP
address.
Subnet Mask: If the IP address is like a street address, then a
subnetwork is like your neighborhood. This will be formatted
in a similar way to the IP address (ie. four numbers up to 255
separated by periods) but contain very different numbers. In
the above example, the Subnet Mask might be something like:
"255.255.255.0".
Default Gateway: This is the address of the "way to the
Internet" - to continue the road analogy, this is like your local
access point to the highway. This is an IP address in the same
format as the others, and is typically very similar to the IP
address of the NVR. To continue the above examples, it might
be something such as: "192.168.1.254".
Auto DNS / Static DNS: Choose how you'd like to define your
DNS servers. We recommend leaving it on Auto unless you've
got a specific reason not to.
Auto DNS: The NVR will automatically choose a DNS server.
This is the recommended setting.
Static DNS: If you need to manually define a DNS server, then
choose Static DNS. This is recommended for advanced users
only.
Preferred DNS Server: "Domain Name System". Everything
on the Internet is located via an IP address - however,
for ease of use, we associate domain names (such as
"www.exampledomainname.com") with those IP addresses.
This index is accessible in many locations online, and we call
those locations "DNS servers".
DNS for STATIC configuration: Under most circumstances, you
can set the DNS Server address to be the same address as
your router (this is usually the same address as Gateway).
DNS for DHCP configuration: Typically, the DNS Server address
will automatically be detected by the NVR. In some cases,
you'll need to enter a value - the address of your router (the
same as the Gateway) should work.
Alternate DNS Server: A backup DNS server. This is here as a
redundancy - your NVR will probably work without one.
MAC Address: The Media Access Control address. This is a
unique code which nothing else should share. You can't change
this one - it's pre-set when the NVR ships out.
