Swann DVR4-2000 Operating Instructions Manual page 23

MEDIA PORT: This is the port that the DVR will use to send information through.
The most important things are that:
1. Nothing else share this port. The default port number is 9000, which is not
used by many other devices/programs. However, particularly if you have
another DVR or DVR-like device, something might be using this port already. If
this is the case, change this value to be unique.
2. That this port is forwarded from your router to the DVR (this process is
called Port Forwarding). Check out or website (www.swannsecurity.com) for
supporting information and an online guide which covers port forwarding
for various popular routers/gateways. Forwarding a port is something like
opening up a fast-lane for network traffic to get to and from your DVR - it will
significantly speed up the flow to and from the DVR stopping 'traffic jams'
which can prevent the DVR operating correctly via the network.
WEB PORT: This is the port through which you will be able to communicate with
the DVR. Like the Media Port, it will need to be forwarded properly in order to
ensure smooth, latency-free communication.
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 DVR 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 things
are that the first three numbers (in the above example "192.168.1.xxx" match the
other devices, and that nothing else on your network share the last number.
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".
It must be the same as the other devices on your network.
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 DVR. To continue the above examples, it might be something such as:
"192.168.1.254".
DNS: A "Domain Name Server". 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 stored in
many locations online, and we call those locations DNS servers.
Remember: After making changes to the settings press/click the APPLY button.
