D-Link DCS-3110 User Manual

Section 1 - Product Overview
DCS-3110 is an ideal network camera for professional surveillance and security applications. This camera adopts a
1.3 mega-pixel progressive scan CMOS sensor and the motion JPEG stream covers three times larger scene which
is also at least three times higher than analog CCTV cameras. This is also a very important consideration in video
surveillance applications, where a high resolution image helps to identify a criminal.
Two video streams with different configurations can be activated simultaneously to address different requirements
for live viewing and recording. Multicast video/audio stream helps to reduce the network transmission load. When a
multicast-enabled router is used, the network camera can serve multiple clients at the same time.
The DCS-3110 has a built-in removable IR-cut filter and is designed for both indoor/outdoor (with enclosure) day/
night applications. The camera is equipped with one digital input and one digital output. An RS-485 port is designed
for external pan/tilt/zoom devices. An 802.3af compliant power over Ethernet (PoE) module is built-in to ease the
installation process.
With the free-bundled 32-channel recording software (D-ViewCam), this network camera provides a total solution for
high quality live viewing and reliable recording.
D-Link DCS-3110 User Manual

Section 1 - Product Overview
• Powerful Surveillance - The DCS-3110 is designed to target the high-end surveil ance market. As mentioned
earlier, a 1.3 mega-pixel progressive scan CMOS sensor covers three times larger view. The DCS-3110
is a powerful network camera for both day and night applications. It effectively reduces motion blur and
distortion as well as jagged edges of recorded images. With a removable IR-cut filter, the Network Camera
always provides high-quality images in both daytime and nighttime. An RS-485 port is designed for external
pan/tilt/zoom devices. It supports DC12V output for external devices like IR light.
• Sharp Image Monitoring - DCS-3110 provides high quality real-time videos in MPEG-4 and JPEG
compression with VGA/QVGA/QQVGA resolution. It is also suitable for narrow space surveillance, like an
• View Live Video from a 3G Mobile Phone - The live video feed of the Network Camera can be pul ed from
the 3G cel ular network by using a compatible cel phone or PDA with a 3G video player. Users are offered
a flexible and convenient way to remotely monitor a home or office in real time, anywhere within the 3GPP
service area.
• Wired PoE Access - For effective surveillance in or around a building, this camera comes with a built-in
802.3af compliant Power Over Ethernet (PoE) module, which eases the installation process and also gives
you the freedom to place the camera where it’s needed. In addition, the 10/100BASE-TX Ethernet port
provides convenient connection to an Ethernet network or to broadband Internet via a router.
• Smart & Easy To Use - The software allows you to view up to 32 cameras on a single computer screen
at one central location. Users can set up automated e-mail alerts to be instantly informed of unusual
activities. In addition, this network camera supports the universal plug-n-play (UPnP™) feature, which al ows
computers running on Windows® XP/Vista to automatical y recognize the camera and adds it to the network.
Sign up with one of the free Dynamic DNS services available on the web to assign a domain name to the
camera ( This allows users to remotely access the camera without having
to remember the IP address.

Section 1 - Product Overview
• Supported Protocols - DCS-3110 supports a wide variety of protocols such as RTSP, FTP, SMTP, NTP
and HTTP. In addition, the camera supports UPnP and DDNS.
• Web Configuration - Using a Web browser, administrators can configure and manage the network camera
directly from its own web page via your network or the Internet. Up to 20 user accounts can be created with
privilege settings controlled by the administrator.
• Connection to External Devices - Supporting auxiliary Input/Output connectors, you can connect the
Network Camera to a variety of external devices such as IR-sensors, switches and alarm relays. Combined
with programmable alarm equipment, you can develop a variety of security applications that are triggered
on alarm-based events. The Network Camera provides an industry standard in/out external connector for
• MPEG4 Multicast Stream Support – Unicast video is delivered through point-to-point transmission. On
the other hand, with a multicast stream, the server streams to a multicast IP address on the network, and
clients receive the stream by subscribing to the IP address. Because there is only one stream from the server
regardless of the number of clients receiving the stream, a multicast stream requires the same amount of
bandwidth as a single unicast stream containing the same content. Using a multicast stream preserves
network bandwidth.
• Samba Client Support – DCS-3110 has a built-in Samba client for NAS, and hence does not require a
direct connection to a PC or any other hardware or software to capture and transfer images.

following RTSP URL command to request a transmission of streaming data.
rtsp://<ip address>:<rtsp port>/<access name for stream1 or stream2>
For example, when the access name for stream 1 is set to live.sdp:
1 : Launch a RTSP player.
2 : Choose File > Open URL. This opens the URL dialog box.
3 : Type the URL command in the text box.
For example:
4 : The live video will be displayed in your player.

RTSP port: The port number that you use for RSTP streaming, the default port number is 554. RTP (Real Time Protocol) Port is used
to streaming audio and video while RTCP (Real Time Control Protocol) port is used to monitor QoS of RTP stream.
Note: RTP video port and RTP audio port must be an “even” number. The numbers of RTCP video port and RTCP audio
port must equal to the numbers of RTP video port and RTP audio port, plus one repetitively.
RTP port for Default port number is 5556.
RTCP port for Default port number is 5557.
Multicast group You may choose to enable multicast for your camera audio and video streaming so that your cameras (sources) and the
address: receivers (clients) can establish the connection to send and receive contents.
An IP Multicast group address is used to send and receive content. Sources use this group address as the destination
address while sending their data packets. Receivers use this group address to inform the network that they are interested
in receiving packets sent to that group.

Two way The two way audio port in DSC-3415 is set to 5060, by default. It can also be assigned to another port number between 1025
audio port: and 65535. This Network Camera supports two way audio communication so that operators can transmit and receive audio
simultaneously. By using the camera’s built-in microphone and an external speaker, users can communicate with people
present around the Network Camera.
Note: Since JPEG only transmits a series of JPEG images to the client, to utilize this feature, make sure the video mode is
set to MPEG-4 and the media option is set to Video and Audio.

Unicast video transmission delivers a stream through point-to-point transmission. On the other hand, multicast video
transmission sends a stream to the multicast group address and allows multiple clients to acquire the stream by
requesting a copy from the Multicast group address.
The five ports can be changed between 1025 and 65535. The multicast RTP port must be an even number and the
multicast RTCP port is multicast RTP port number plus one, and thus always be odd. When the multicast RTP port
changes, the multicast RTCP port will change accordingly.

Camera and are judged to exceed the defined threshold, a red bar rises. Meanwhile, the motion detection window will
be outlined in red. Utilizing this device as a trigger source, photos or videos can be captured instantly and sent to the
remote server (Email, FTP).

A green bar indicates that even though motions are detected, the event wil not be triggered because the image variations
are still falling under the defined threshold.

Section 4 - Configuration
How does motion detection work?
There are two parameters for setting the motion detection: Sensitivity and Percentage. In the illustration above, frame
A and frame B are two sequential images. Pixel differences between the two frames are detected and highlighted in
gray (frame C), and will be compared with the sensitivity setting. Sensitivity is a value that expresses the sensitivity to
moving objects. Higher sensitivity settings are expected to sense a slight movement while smaller sensitivity settings
tend to neglect it. When the sensitivity is set to 70%, the Network Camera defines the pixels in the purple areas as
“alerted pixels” (frame D). Percentage is a value that expresses the proportion of “alerted pixels” to all pixels in the
motion detection window. In this case, 50% of pixels are identified as “alerted pixels”. When the percentage is set to
30%, the motions are judged to exceed the defined threshold; therefore, the motion window will be outlined in red.
For applications that require higher security management, it is suggested to set higher sensitivity settings and smaller
percentage values.

Frequently Asked Questions
This chapter provides solutions to problems that may occur during the installation and operation of the DCS-3110.
Read the following descriptions if you are having any problems.
Megapixel PoE Network Camera Features
1. What is a Megapixel PoE Network Camera?
The Megapixel PoE Network Camera is a stand-alone system connecting directly to an Ethernet or Fast Ethernet network. The Megapixel
PoE Network Camera differs from a conventional PC Camera because it has an integrated system with built-in CPU and web-based
solutions, providing a low cost solution that can transmit high quality video images for monitoring. The Megapixel PoE Network Camera
can be remotely managed, accessed and controlled using a web browser from any computer over an Intranet or Internet.
2. What is the maximum number of users that can access DCS-3110 simultaneously?
The maximum number of users that can log onto the Megapixel PoE Network Camera at the same time is 10. Please keep in mind the
overall performance of the transmission speed will be reduced if many users have logged on to the camera simultaneously.
There is no limit on the number of users when a multicast-enabled router is being used. The multicast protocol helps reduce the network
bandwidth consumption.
Note that the Network Camera must be configured to enable multicast streaming. For more information, see RTSP Streaming on page
3. What algorithm is used to compress the digital image?
The Megapixel PoE Network Camera utilizes MPEG-4 simple profile or MJPEG Mode image compression technology providing high quality
images. MJPEG is a standard for image compression and it can be applied to various web browsers and application software without
installing any extra software
4. Can I capture still images from the Megapixel PoE Network Camera?
Yes you can capture still images using the snapshot function.
D-Link DCS-3110 User Manual

Section 5 - Frequently Asked Questions
Megapixel PoE Network Camera Installation
1. Can the Network Camera be used outdoors?

The Megapixel PoE Network Camera is not weatherproof. It needs to be equipped with a weatherproof case for outdoor use but it is not
2. When physically connecting the Network Camera to a network, what network cabling is required?
The Megapixel PoE Network Camera uses Category 5 UTP cable allowing 10 Base-T and 100 Base-T networking solutions.
3. Can the Network Camera be setup as a PC-cam on a computer?
No, the Megapixel PoE Network Camera is used only on an Ethernet or Fast Ethernet network. The D-Link DSB-C110, DSB-C310, can
be used as a PC Camera (Webcam).
4. Can the Network Camera be connected to the network if it consists only of private IP addresses?
Yes, the Megapixel PoE Network Camera can be connected to a LAN using only a private IP address.
5. Can the Network Camera be installed and work if a firewall exists on the network?
If a firewall exists on the network, port 80 is open for ordinary data communication. The DCS-3110 uses port 5002 for streaming audio
and port 5003 for streaming video. These ports (or the ports you have specified in the Setup Tab in the Configuration screen) need to be
opened on the firewall.
6. Why am I unable to access the Network Camera from a web browser?
If a router or firewall is used on the network, the correct ports for the DCS-3110 may not be configured on the router or firewall. To correct
the problem, you need to determine if the DCS-3110 is behind a router or firewall and if the router or firewall is properly configured for
the ports the DCS-3110 is using. Refer to Page 40 for help in opening the correct ports on a router or firewall for use with the DCS-3110.
Other possible problems might be due to the network cable. Try replacing your network cable. Test the network interface of the product
by connecting a local computer to the unit. If the problem is not solved, the Megapixel PoE Network Camera might be faulty.
7. Why does the Network Camera work locally but not externally?
• This might be caused by network firewall protection. The setting of the firewall may need to be changed in order for the Megapixel PoE
Network Camera to be accessible outside of your local LAN. Check with the Network Administrator for your network.
• Make sure that your Megapixel PoE Network Camera isn’t conflicting with any Web server you may have running on your network.
• The default router setting might be a possible reason. Check that the configuration of the router settings allows the Megapixel PoE
Network Camera to be accessed outside of your local LAN.

the camera to a router with DHCP enabled.
• This error can also occur if the Installation Wizard icon had been clicked more than once from the setup wizard.
9. Noisy images occur. How can I solve the problem?
The video images might be noisy if the Megapixel PoE Network Camera is used in a very low light environment. To solve this issue you
need more lighting.
10. The images appear to be of poor quality, how can I improve the image quality?
• 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.
• The configuration on the Megapixel PoE Network Camera image display is incorrect. Through the Setup > Image Setup section of
the Web management you need to adjust the image related parameters such as brightness, white balance and power line frequency
for fluorescent light.
