This option can turn off the wireless function. The

camera server will detect the connection type when

booting, it will detect a wired connection ﬁrst, and

then wireless. If wireless is not connected during

booting, it will not detect again. If wireless is disabled,

the camera will not detect wireless during booting.

(Service Set Identiﬁer) is a name that identiﬁes a

wireless network. Access Points and wireless clients

attempting to connect to a speciﬁc WLAN (Wireless

Local Area Network) must use the same SSID. The

default setting is

dlink

.

Click on the drop-down list and select from the

following options:

Infrastructure

- connecting the WLAN using an

Access Point such as the DWL-±100AP or a DI-µ±³ wireless router.

Ad-Hoc

– wireless mode used when connecting directly to a computer equipped with a wireless adapter in a peer-to-peer

environment.

In Infrastructure mode, the wireless channel is automatically selected by the camera. In Ad-Hoc mode, the default wireless

channel setting is channel µ. Select the channel that is the same as the other wireless devices on your network.

Select the transmission rate on the network.

Auto

is the default setting.

Preamble Type - Short or Long. If your wireless network support Short Preamble, then enabling it can boost overall

throughput. However, if any wireless device does not support Short Preamble, then it will not be able to communicate with

your network. If you are not sure whether your radio supports the Short RF preamble, then make sure you disable this

feature. Long Preamble is the default, as it is a required setting for Wi-Fi compatibility.

Select the encryption type from the drop-down list. The default setting for encryption is None, which means the security is

disabled.

Click the Dynamic DNS button on the left side of the Setup screen to access Dynamic DNS settings.

Dynamic DNS

Dynamic DNS (Domain Name Service) is a method of keeping a domain name linked to a changing (dynamic)

IP address. With most Cable and DSL connections, you are assigned a dynamic IP address and that address

is used only for the duration of that speciﬁc connection. With the DCS-2120, you can set up your DDNS

service and the DCS-2120 will automatically update your DDNS server every time it receives a different IP

address.

Select to enable or disable the DDNS function.

Select your Dynamic DNS provider from the drop-down list.

Enter the host name of the DDNS server.

Enter your username or e-mail used to connect to the DDNS server.

Enter your password or key used to connect to the DDNS server.

Select the option for color or monochrome

video display.

This option allows you to choose the

frequency of the power line for different

regions (Power Line Frequency in US:

60Hz).

Vertically rotate the video.

Horizontally rotate the video. Check

both flip and mirror if the DCS-2120 is

installed upside down.

White Balance is related to the color

temperature. Color temperature is a way of

measuring the quality of a light source. It is

based on the ratio of the amount of blue light

to the amount of red light, while the green

light is ignored. The unit for measuring this

ratio is in degrees Kelvin (K). Light with a higher color temperature (i.e. larger Kelvin value) has “more” blue

light than a light with a lower color temperature. The default setting for white balance is “Auto”.

Image Brightness is adjustable, you can set from among eleven levels ranged from -5 to +5. The default

setting is zero.

Image Setup

Click the Image Setup button on the left side of the Setup screen to access additional settings that affect how the video

image appears. From this screen you can ﬁne tune the video image.

Select this option to switch to computer viewing.

Select this option to switch to mobile device

viewing. The frame size will change to 176x144,

5 FPS and 40kbps video quality.

There are 4 options for the size of the video

display. You can select 160x120, 176x144,

320x240, or 640x480. The maximum frame rate

is 30fps for all resolutions.

Limits the maximum refresh frame rate. The

frame rate is used with the Video quality control

setting (below) to optimize bandwidth utilization

and video quality.

Determines how many repeated P frames will

appear after one I frame. A large key frame

interval can reduce the bit rate, but cause image

to be corrupted longer if there is packet loss

while transmitting. The video quality may be poor due to the sending of maximum frame rate within the limited

bandwidth when images are moving rapidly. Consequently, to ensure detailed video quality (quantization rate)

regardless of the network, it will utilize more bandwidth to send the maximal frames

Used when images change drastically.To ﬁx the bandwidth utilization regardless of the video quality, choose

Fixed bit rate and select

the desired bandwidth. The video quality may be reduced in order to send maximum

frames with limited bandwidth, especially when images change drastically. For higher video detail regardless

of the bandwidth selection, select Fixed quality and select a video quality level. This setting will utilize more

bandwidth to send the maximum frames when images change drastically.

Click the Audio and Video button on the left side of the Setup screen to access audio and video settings that affect

how the audio and video appears.
