> DHCP function
There are only dynamic IP users in the internet environment. The address is continuously changing since it
is not a static IP.
For example, if there is a house but the address is frequently changed, the mail can not be delivered in
normal way. So, whenever the address is changed, you have to ask a town office to trace it. The role of the
town office is the DHCP function.
The DHCP Server automatically traces and records the IP change whenever it can access the data. The
product, LDV-S802, operates as a dedicated DHCP server.
Notes
The dynamic IP user selects the DHCP "ON" and connects to the following site http://www.lg-security-
s800.com and logs -in for the remote monitoring.(How to register membership to use is explained on
the above site).
The NETWORK light on front panel only blinks when the system is connected by the user. Therefore it
will not blink when simply connected to the internet.
> IP INFORMATION SETUP
It is used when the network connection use static IP. The dynamic IP user doesn't have to make configura-
tions.
Fill it with ISP information provided to setup the static IP for use.
For example :
-
IP ADDR: 192.168.123.51
-
SUBNET: 255.255.255.0
-
GATEWAY: 192.168.123.254
-
DNS: 168.126.63.1
Notes
• IP Address
This is the unique name of device in TCP/IP network. This is an expensive internet line which is normally
used for servers. If you are using a static IP, enter the IP address.
• Subnet Mask
Has 32Bit length figures to decide the number of bits used as network address in IP address (= Address
mask)
• Gateway
Used to combine protocols or different architectures of network.
• DNS
Instead of the address being composed of numbers (ex. 168.126.063.001), this makes the connection
with easily memorable letters or words like a domain.
• To input the IP, it should be done by the direction key because the numeric key is not available.
> PORT
Configure the network port. And the changed port should be applied if the system is not connected even
after the configuration. User may consult to administrator or service provider if the port is being used by
another system or blocked at the router (factory default port: 5000).
