 Here you can choose between the three different types of networks 

that the DVR can be connected to. The three types of networks are:

 Is a system where one device on 

your network (usually a router) will automatically assign IP addresses to devices 
connected to the network.

 Static networks require all devices to have their IP addresses manually 

defined, as there is no device dedicated to automatically assigning addresses.

 An advanced protocol that allows the DVR to be more directly connected 

via a DSL modem. This is an option for advanced users only.

 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 to identify their position on the electronic network. The device 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.

 If the IP address is like a street address, then a subnetwork is like your 

neighbourhood. This will be formatted in a similar way to the IP address (e.g. 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”.

 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 device. 
To continue the above examples, it might be something such as “192.168.1.254”.

 Everything on the Internet is located via an IP address - 

however, for ease of use, we associate domain names with those IP addresses.

 A backup DNS server. This is here as a redundancy; your device 

will probably work without one.
