Wizard Page 2: LAN Setting
This page is about the select of Static IP or DHCP ON.
LAN: You can configure this PT Internet Camera to obtain its address automatically
or manually assign. If there is a DHCP server in your network environment
and you select "DHCP ON", PT Internet Camera can automatically obtain an
IP address. If you don't have DHCP server or you want to use fixed IP
address, please select "Static IP" and fill in the following fields with proper
parameters.
IP Address: IP address is a unique number for identifies this device on the WAN or LAN.
These numbers are usually shown in groups separated by periods, for
example: 192.168.0.200
Subnet Mask: Subnets allow network traffic between hosts to be separated based on the
network's configuration. In IP networking, traffic takes the form of packets. IP
subnets advance network security and performance to some level by
organizing hosts into logical groups. Subnet masks contain four bytes and
usually appear in the same "dotted decimal" data. For example, a very
common subnet mask in its binary demonstration 11111111 11111111
11111111 00000000 will usually be shown in the corresponding, more
readable form as 255.255.255.0.
Def. Gateway: A gateway is a piece of software or hardware that passes information
between networks. You'll see this term most often when you either log in to
an Internet site or when you're transient email between different servers.
DNS1: When you send email or position a browser to an Internet domain such as
xxxxx.com, the domain name system translates the names into IP addresses.
The term refers to two things: the conventions for naming hosts and the way
the names are control across the Internet.
DNS2: The same function as DNS1. It is optional, not necessary
