Power line frequency

(for fluorescent light)

Fluorescent lights may intermittently flash depending

on the AC power line frequency. Change the

frequency setting to eliminate a flashing image when

the light source is fluorescent light.

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.

To fix the bandwidth utilization regardless of the video

quality, choose

Fix 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

Fix quality

and select

a video quality level. This setting will utilize more

bandwidth to send the maximum frames when

images change drastically.

Mirror -

Horizontally rotate the video. Check both

Recommendations for setting video for the best

performance:

±Best performance² means the image refresh rate should be the fastest possible

and the video quality should be the best possible at the lowest network bandwidth

possible. Three factors,

Maximum frame rate

,

Fix bit rate

, and

Fix quality

in

the

Video Configuration

page, are related to performance.

My priority is real-time motion images

To achieve a real-time visual effect, the network bandwidth should be large

enough to transmit 20 image frames per second (fps) or more. If you are on a

broadband network over 1 Mbps, you can set

Fix bit Rate

to 1000Kbps or

1200Kbps, or set

Fix quality

to achieve the maximum frames. The maximum

frame rate is 25 in 50Hz system and 30 in 60Hz system. If your network

bandwidth is more than 384Kbps, you can adjust

Fix bit rate

according to your

bandwidth and set the maximum frame rate of 25 to 30.

If the images vary dramatically in your environment, you may slow down the

maximum frame rate to 20 to decrease the transmitted data for better video

quality. Since the human eye could not easily differentiate between 20 and 25

or 30 frames per second, the slower frame rate will not be noticed. If your

network bandwidth is below 384 Kbps, you should adjust the bit rate according

to your bandwidth and experiment to allow for the best frame rate that can be

achieved. The faster frame rate in a slow network will blur the images. You may

also try to choose

Half

in size option for better images or

Half x 2

for larger

image size. Because the network has burst constraints and everyone°s

environment is not the same, any poor connection will impair normal

performance.

My priority is clear identification for each image

To have the best video quality, you should set

Fix quality

to

detailed

or

excellent

and tune the

Maximum frame rate

to suit

your network bandwidth. If you get

some broken pictures in a slow network, you can set

TCP protocol

in

Connection type

for a more accurate transmission but the received images

may have a lag. Note that any slow connection with multiple users will impair

performance.

Recommendations for setting video for the best

performance (continued):

I want to compromise between real-time and clear images

If you have a broadband network, set

Fix quality

to

Good

image quality, or

higher,

instead of setting the

Bit rate

. Otherwise, fix the bit rate according to

your actual network speed and set the frame rate to 30. If the image quality is

low, select a lower frame rate above 15. If the image quality is still not improved,

select a lower bit rate.

Click the Image Settings button from the Configuration screen to access the

settings that affect how the video image appears.

From this screen you can fine tune the video image.

Image

Brightness,

Contrast

,

Saturation

and

Hue

are all adjusted in the same

manner. For each video compensation you can set from among eleven levels

ranged from -5 to

+5.

The default setting is zero for each adjustment.

You may press

to fine-tune the image and see what affect the setting

will have on the image. When the image is acceptable, press

to store the

image settings, or

to recall the original settings. If settings are changed

without saving, they will be used until the next system start-up.

Configuration > Advanced > Motion Detection

Click the

Motion Detection

button from the

Configuration

screen to access

settings that affect how the

DCS-2100+

Internet Camera can serve as a security

device by recording only when motion is detected.

Enable motion detection

-

Check this option to turn on the motion detection.

Window Name

-

The text entered here will show at the top of the

window.

Sensitivity -

Sets the measurable difference between two

sequential images that would indicate motion.

Percentage -

Sets the amount of motion in the window being

monitored that is required to initiate a motion

detected alert.

Note:

Setting a higher

Configuration > Advanced >Motion Detection (continued)

To display motion detection, a graphic bar will rise or fall depending on the

image variation.

A green bar means the image variation is under the monitoring level, and no

motion detection alert is triggered. A red bar means the image variation is over

the monitoring level and a motion detected alert is triggered.

When the bar

goes red, the window that the motion is detected in will also be outlined in red

(note: remember that you can have up to 3 windows selected for motion

detection). You can return to the

DCS-2100+

Home Page and the monitored

window will not be visible, but the red frame will show on the home page when

motion is detected.

New -

Click to add a new window. A maximum of three

windows can be opened simultaneously. Use

your mouse to drag the window frame to resize

or the title bar to move. Clicking on the ´x° at the

upper right corner of the window will close the

window.

Save -

Saves the related settings of that window.
