Wireless Installation Considerations
The D-Link wireless internet camera lets you access your network using a wireless connection from virtually anywhere
within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location
of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to
maximizing wireless range is to follow these basic guidelines:
1.Keep the number of walls and ceilings between the D-Link adapter and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
2.Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
3.Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4.Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5.If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.

Recommendations for Setting Video for the Best Performance:
“Best performance” 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.
Recording settings for 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 320x240
in size option for better images or 640x480 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.
Recording settings for 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.
Recording settings 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.

Using the Monitor Program
This section depicts, in detail, how to manipulate the monitor tool.
Connection of the DCS-3420
Once you have the privilege to connect to the DCS-3420, the cameras will automatically appear in the video area in
the order they are connected. Once you have set up the camera in the video channel, the color of the channel number
will turn green, indicating that the camera has been added to IP surveillance. If you do not set up the camera for the
video channel, the color of the channel number will be gray.
There is a unique light signal associated with each channel number. It indicates the status of the dedicated video
channel, which is depicted as follows:
Off: The video channel is not connected with any DCS-3420 yet.
Green: The green light means the DCS-3420 associated with this channel number is connected, and the video is monitored
in the video area.
Red: The red light indicates the video from this channel is recording into the video database. In this mode, you don’t have
to drag and drop the channel to the video area. This means that this application software supports real-time recording
with and without real-time monitoring for the dedicated video channel.
Blink: With the motion detection mechanism set in the DCS-3420, the light of the corresponding channel
will blink once the motion event is triggered.
If you do not want to monitor one video, you can drag and drop the video (in the video area) to the
trash can in the common control area of the monitor program. The following section will demonstrate
the procedures for “drag and drop” step-by-step.

camera by DO switch.
When the color of a DI/DO channel number is gray, that means the video channel has not yet
been connected to a camera.
Alert Message
If you have checked the box “Enable Motion Detect” or “Enable Digital Input” on the Camera
Configurations > Alert Settings screen, the alert message will show in the window shown
above. Once the alert, caused by motion detection or a digital input level change is triggered,

can display, a scroll bar will appear.
The message format is described as follows:
“time”=>”alert type” #”channel number”(“win1”,”win2”,”win3”)
For example, the message “PM 02:41:00=>MO #1(0,1,1)” means that this is a motion
detection alert occurring at 02:41:00 PM in Motion Window 2 and Motion Window 3, for camera #1. If the message “PM
02:41:56=>DI #1” is listed, that means there is an alert triggered by the DI, for camera #1, at 02:41:56 PM .

Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DCS-3420 offers the following types of security:
• WPA-PSK (Pre-Shared Key)
• WEP (Wired Equivalent Privacy)
What is WEP?
WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption
algorithm. WEP provides security by encrypting data over your wireless network so that it is protected as it is transmitted
from one wireless device to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using
WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption
requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using
characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters) format.
ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX
for use over the network. Four keys can be defined so that you can change keys easily.
D-Link DCS-3420 User Manual
Section 4 - Security
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys
using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been
tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol
(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MAC
address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key
encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must
be the exact same key entered on your wireless router or access point.

D-Link DCS-3420 User Manual
Section 4 - Security
After you have completed the setup of the DCS-3420 outlined in the Quick Installation Guide you will have an
operating camera that has an assigned IP Address. Because you are using a router to share the Internet with
one or more PCs, the IP Address assigned to the Internet Camera will be a local IP Address. This allows viewing
within your Local Area Network (LAN) until the router is configured to allow remote viewing of the camera over
the Internet.
Assign a Local IP Address to Your Camera
Run the Installation Wizard program from the CD included with the DCS-3420. Follow the steps in the Quick
Installation Guide to configure the DCS-3420. The camera will be assigned a local IP Address that allows it to

Router Set-Up and Installation
The following steps generally apply to any router that you have on your network. The D-Link DI-624 is used as an
example to clarify the configuration process. Configure the initial settings of the DI-624 by following the steps outlined
in the DI-624 Quick Installation Guide.
Access the Router with Your Web Browser
If you have cable or DSL Internet service, you will most likely have a dynamically assigned WAN IP Address. ‘Dynamic’
means that your router’s WAN IP address can change from time to time depending on your ISP. A dynamic WAN IP
Address identifies your router on the public network and allows it to access the Internet. To find out what your router’s
WAN IP Address is, go to the Status menu on your router and locate the WAN information for your router (as shown
on the next page). The WAN IP Address will be listed. This will be the address that you will need to type in your Web
browser to view your camera over the Internet.
Your WAN IP Address will be listed on the router’s
Status > Device Info page.
D-Link DCS-3420 User Manual
Section 4 - Security
Note: Because a dynamic WAN IP can change from time to time depending on your ISP, you may want to obtain a
Static IP address from your ISP. A Static IP address is a fixed IP address that will not change over time and will be more
convenient for you to use to access your camera from a remote location. The Static IP Address will also allow you to
access your camera attached to your router over the Internet.
Open Virtual Server Ports to Enable Remote Image Viewing
The firewall security features built into the DI-624 router prevent users from accessing the video from the DCS-3420
over the Internet. The router connects to the Internet over a series of numbered ports. The ports normally used by the
DCS-3420 are blocked from access over the Internet. Therefore, these ports need to be made accessible over the
Internet. This is accomplished using the Virtual Server function on the DI-624 router. The Virtual Server ports used by
the camera must be opened through the router for remote access to your camera. Virtual Server is accessed by clicking
on the Advanced tab of the router screen.
Follow these steps to configure your router’s Virtual Server settings:
1 Click Enabled.
2 Enter a different name for each entry.
3 Enter your camera’s local IP Address (e.g., in the example in step 2 on page 129) in the
Private IP field.
4 Select TCP for HTTP port and both (TCP and UDP) for Audio and Video channel port.
5 If you are using the default camera port settings, enter 80 into the Public and Private Port section, click Apply.
6 Scheduling should be set to Always so that the camera images can be accessed at any time.

Section 4 - Security
Repeat the above steps adding the port 5002 and 5003 to both the Public and Private Port sections. A check mark
appearing before the entry name will indicate that the ports are enabled.
Important: Some ISPs block access to port 80 and other commonly used Internet ports to conserve bandwidth. Check
with your ISP so that you can open the appropriate ports accordingly. If your ISP does not pass traffic on port 80, you
will need to change the port the camera uses from 80 to something else, such as 800. Not all routers are the same, so
refer to your user manual for specific instructions on how to open ports.
Enter valid ports in the Virtual Server section of your router. Please make sure to check the box next to the camera
name on the Virtual Server List to enable your settings.

Appendix E - Warranty
Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited Warranty:
• Only to the person or entity that originally purchased the product from D-Link or its authorized reseller or distributor, and
• Only for products purchased and delivered within the fifty states of the United States, the District of Columbia, U.S. Possessions or Protectorates, U.S. Military Installations, or addresses with an APO or FPO.
Limited Warranty:
D-Link warrants that the hardware portion of the D-Link product described below (“Hardware”) will be free from material defects in
workmanship and materials under normal use from the date of original retail purchase of the product, for the period set forth below
(“Warranty Period”), except as otherwise stated herein.
• Hardware (excluding power supplies and fans): One (1) year
• Power supplies and fans: One (1) year
• Spare parts and spare kits: Ninety (90) days
The customer’s sole and exclusive remedy and the entire liability of D-Link and its suppliers under this Limited Warranty will be, at DLink’s option, to repair or replace the defective Hardware during the Warranty Period at no charge to the original owner or to refund the
actual purchase price paid. Any repair or replacement will be rendered by D-Link at an Authorized D-Link Service Office. The replacement
hardware need not be new or have an identical make, model or part. D-Link may, at its option, replace the defective Hardware or any part
thereof with any reconditioned product that D-Link reasonably determines is substantially equivalent (or superior) in all material respects
to the defective Hardware. Repaired or replacement hardware will be warranted for the remainder of the original Warranty Period or ninety
(90) days, whichever is longer, and is subject to the same limitations and exclusions. If a material defect is incapable of correction, or if
D-Link determines that it is not practical to repair or replace the defective Hardware, the actual price paid by the original purchaser for the
defective Hardware will be refunded by D-Link upon return to D-Link of the defective Hardware. All Hardware or part thereof that is replaced
by D-Link, or for which the purchase price is refunded, shall become the property of D-Link upon replacement or refund.

Appendix E - Warranty
Limited Software Warranty:
D-Link warrants that the software portion of the product (“Software”) will substantially conform to D-Link’s then current functional specifications
for the Software, as set forth in the applicable documentation, from the date of original retail purchase of the Software for a period of ninety
(90) days (“Software Warranty Period”), provided that the Software is properly installed on approved hardware and operated as contemplated
in its documentation. D-Link further warrants that, during the Software Warranty Period, the magnetic media on which D-Link delivers the
Software will be free of physical defects. The customer’s sole and exclusive remedy and the entire liability of D-Link and its suppliers under
this Limited Warranty will be, at D-Link’s option, to replace the non-conforming Software (or defective media) with software that substantially
conforms to D-Link’s functional specifications for the Software or to refund the portion of the actual purchase price paid that is attributable
to the Software. Except as otherwise agreed by DLink in writing, the replacement Software is provided only to the original licensee, and
is subject to the terms and conditions of the license granted by D-Link for the Software. Replacement Software will be warranted for the
remainder of the original Warranty Period and is subject to the same limitations and exclusions. If a material non-conformance is incapable
of correction, or if D-Link determines in its sole discretion that it is not practical to replace the non-conforming Software, the price paid by
the original licensee for the non-conforming Software will be refunded by D-Link; provided that the non-conforming Software (and all copies
thereof) is first returned to D-Link. The license granted respecting any Software for which a refund is given automatically terminates.
Non-Applicability of Warranty:
The Limited Warranty provided hereunder for Hardware and Software portions of D-Link’s products will not be applied to and does not cover
any refurbished product and any product purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the
sellers, or the liquidators expressly disclaim their warranty obligation pertaining to the product and in that case, the product is being sold
“As-Is” without any warranty whatsoever including, without limitation, the Limited Warranty as described herein, notwithstanding anything
stated herein to the contrary.
