Q:

The images appear to be of poor quality, how can I improve the image

quality?

A1:

Make sure that your computer°s display properties are set above 256 colors.

Using 16 or 256 colors on your computer will produce dithering artifacts in the

image, making the image appear to be of poor quality.

A2:

The configuration on the Internet Camera image display is incorrect. Through

the

Advanced>Configuration

section of the Web management you need to

adjust the image related parameters

such as brightness, contrast, hue and

power line frequency for fluorescent light . Please refer to the

Advanced>Configuration>Video

section on Page 35 and 36 for detailed

information.

How to PING Your IP Address

The PING (Packet Internet Groper) command can determine whether a specific

IP address is accessible by sending a packet to the specific address and waiting

for a reply. It can also provide a very useful tool to confirm if the IP address

conflicts with Internet Camera over the network.

Follow the step-by-step procedure below to utilize the PING command but first

you must disconnect Internet Camera from the network.

Start a DOS window.

Type ping x.x.x.x, where x.x.x.x is the IP address of the Internet Camera.

The replies, as illustrated below, will help diagnose any connection problems.

There is a button hidden in the pinhole beside the Ethernet socket. It is

used to

reset

the system or

restore

the factory default settings.

Sometimes resetting the

DCS-2100+

will return the system back to a

normal state. If the system still has problems after reset, restore the

factory settings and install again:

RESET

:

1. Lightly insert a paper clip (or a similar sized tool) into the

reset hole on the back of the camera, press lightly and

then release the button.

2. The LED on the front of the camera will begin blinking red

and green.

3. When the LED stops the blinking the reset has completed.

RESTORE

:

1. Insert the paper clip or other tool and press on the button

continuously.

2. Wait for the LED on the front of the camera to blink red

and green and hold the button through two cycles of

blinking (about 5-7 seconds.)

3. Withdraw the tool after the second cycle of the LED

blinking and a factory restore has been completed.

Restoring the factory defaults will result in the

loss of any previous settings and will require

running the

IP Installer

to return the

DCS-2100+

to a normal state.

I/O Connector

I/O Connector Definition for the Internet Camera

The

DCS-2100+

provides a general I/O terminal block with one digital input and

one relay switch for device control. Pin 1 and pin 2 can be connected to an

external sensor and the state of voltage will be monitored from the initial state

´LOW°. The relay switch of pin 3 and pin 4 can be used to turn on or off the

external device.

The I/O connector provides the physical interface for digital output (DO) and

digital input (DI) that is used for connecting a diversity of external alarm devices

to the Internet Camera such as IR-Sensors and alarm relays.

The digital input is used for connecting external alarm devices and once triggered

images will be taken and e-mailed.

Adjusting the Camera Focus

The

DCS-2100+

Internet Camera features an interchangeable C/CS-type lens

that can be used for different applications as necessary. It supports rotational

focus control so the lens can be adjusted to focus under normal and stable

conditions to maximize the image quality of the Internet Camera.

To adjust the focus of the lens you will need to turn the lens slowly either

clockwise or counterclockwise until the desired image appears. DO NOT

overturn the lens in either direction as it will be out of focus. Unless you want to

substitute the lens DO NOT unscrew more than 1.0mm apart from the Fixed

Lens Assembly.

To help you get the best image quality, keep in mind that while adjusting the

cameras focus you can preview the image quality from your Web browser.

mount lens commonly used within the surveillance industry.

Follow the instructions below to replace the supplied lens with any C or CS-

mount lens.

1.

Unscrew the Internet Camera lens

2.

When using a C-mount lens, attach the new lens to a CS to C-mount

adapter.

Screw the new lens onto the Internet Camera.

4.

Refer to

Adjusting the Internet Camera Focus

on the previous page.

5.

Refresh the Web browser and monitor the results from the Internet Camera.

Warning!

Direct exposure to sunlight may cause permanent

damage to the CMOS sensor. Therefore do not ex-

pose the Internet Camera°s lens directly to sunlight.

When operation is required in glaring light environment,

it is recommended to use an iris lens.

The Internet Camera is designed for indoor usage and if your appli-

cation requires prolonged exposure to sunlight, a sun visor is rec-

ommended to protect the Internet Camera.
