DCS-G900 Conﬁguration

Infrastructure

is a wireless connection using an access point as

a transmission point of all wireless devices.

Ad-Hoc

is a wireless

connection used without an access point. This basically connects the

PC directly to the DCS-G900. This is done using the on-board wireless

adapter on the DCS-G900 connected to a wireless adapter on the

PC.

Service Set Identiﬁer is an identiﬁer for the wireless network name that

other devices can recognize.

This page will allow you to select a wireless network that the DCS-G900

was able to detect upon booting up (see page 14).

The default wireless channel setting is channel 6. Select the channel

that is the same as the other wireless devices on your network. For the

U.S. region, there are up to 11 channels and anyone of them can be

selected to achieve the best signal.

This can be selected to restrict bandwidth usage of the DCS-G900

in a high trafﬁc network so that the camera does not consume all the

bandwidth. If too much bandwidth is being used in a network that cannot

support it, excessive lag during video transmission may occur. Lowering

the transmission rate will sometimes help.

There are 4 key ﬁelds that you are able to input

the security keys. This is in case you have more

than 1 network that you can connect to. Instead

of having to put in the encryption key every time

you can select key 1, 2, 3, or 4. This is especially

helpful for 128-bit HEX (52 characters!).

This is where you can select which key you

want to use.

In

Open

mode, anyone with the right SSID can

connect to the camera, but in

the user will need to have the right encryption

key to connect the camera thereby providing

Advanced Setting

This represents the amount of time between beacon transmissions, in

which the beacon interval tells the Router/Access Point on the network

how long they can wait in low-power mode before waking up the IP

camera.

Note:

A beacon is a packet sent by the IP camera to inform the

Router/Access Point of the IP camera’s presence and readiness. The

Router/Access Point and IP camera are all on the same network.

A preamble is a signal used in network communications to synchronize

the transmission timing between two or more systems. Proper timing

ensures that all systems are interpreting the start of the information

transfer correctly. Part of the frame that is transmitted by an 802.11

station is called the preamble. The original 802.11 speciﬁcation (which

deﬁned only 1 and 2Mbps operation), deﬁned only a long preamble that

uses a 128 bit sync ﬁeld. When the

high rate

, i.e. 11Mbps, 802.11b

standard was created, an optional short preamble using a 56 bit

sync

ﬁeld was added. This was intended to improve the efﬁciency of the

wireless network for more

real-time

applications such as streaming

video. Selecting short preamble may improve video quality.

Dynamic Host Conﬁguration Protocol is a networking

protocol that will allow leasing of an IP address by the

client from a server for a speciﬁed amount of time. This

alleviates the task of the user from having to keep track

of available IP Addresses on the network.

If you use the DCS-G900 to connect directly to the

Internet you will need to put in the user name and

password that was given to you when you initially set up

your account with the Internet Service Provider.

This is the IP Address of your ISP’s Domain Name Server, if you are

using a ﬁxed IP Address you will need to know this, if not you will need

to contact your ISP or your network administrator.

If you have set up the DDNS service you will need to put in your user

name and password. This will allow the DDNS to track your IP Address

even if it changes constantly. DDNS is disabled by default.

Most ISPs do not open port 80 (a DCS-G900 default video transfer port)

for their residential customers, the DCS-G900 has the ability to use a

different port by enabling the second http port for its video transfer.

Port

Number:

If the second port is enabled, it will automatically disable

the default port 80. Any unused ports can be used such

as port 800, 801, etc. Remember that if the DCS-G900

is behind a router you would need to forward that port

to the DCS-G900’s IP Address. When accessing the

camera you would need to type the camera’s IP Address

+ the port number (http://xxx.xxx.xxx.xxx:port number,

or http://192.168.0.20:800 for example). Please refer to

“Installing the DCS-G900 Behind a Router” on page 39.

UPnP is short for Universal Plug and Play which is a networking

architecture that provides compatibility among networking equipment,

software, and peripherals. The DCS-G900 is an UPnP enabled internet

camera, and this function will work with operating systems such as

Windows

®

XP. If you do not want to use the UPnP functionality, it can be

disabled by selecting

Disabled

. This function is enabled by default.
