1. Product Description
This manual applies to the VK2-ENCODER.
The VK2-ENCODER supports the network service for an existing analog camera. An analog
image entered can be monitored on a real-time screen regardless of distances and locations.
By using its dedicated program, many users are able to have an access to the VK2-
ENCODER at once or a single user can monitor various VK2-ENCODERs at the same time. It
also enables users to play, store and retrieve a monitoring image by using a PC. All the
settings and real-time monitoring screens are also provided through an access to the web.
The VK2-ENCODER is a one-port video transmitter including two-way audio, fully featured
for security surveillance and remote monitoring needs. It is based on the DSP compression
chip, and can digitize one analog video source and make it available on the network as real-
time, full frame rate Motion JPEG and H.264 (or MPEG-4) video streams.
The VK2-ENCODER is equipped with RS-485 port for connecting third party PTZ systems.
The alarm input and alarm output can be used to connect various third party devices, such
as, door sensors and alarm bells.

The VK2-ENCODER offers the highly efficient H.264 video compression, which drastically
reduces bandwidth and storage requirements without compromising image quality. Motion
JPEG is also supported for increased flexibility.
•Dual streams
The VK2-ENCODER can deliver dual video streams simultaneously at full frame rate in all
resolutions up to D1 (720x480 in NTSC, 720x576 in PAL) using Motion JPEG and H.264 (or
MPEG-4). This means that several video streams can be configured with different
compression formats, resolutions and frame rates for different needs.
•Image setting adjustment
The VK2-ENCODER also enables users to adjust image settings such as contrast, brightness
and saturation to improve images before encoding takes place.
•Intelligent video capabilities
The VK2-ENCODER includes intelligent capabilities such as enhanced video motion
detection. The encoder‟s external inputs and outputs can be connected to devices such as
sensors and relays, enabling the system to react to alarms and activate lights or open/close
doors.
•Power over Ethernet
Support for Power over Ethernet (IEEE802.3af) enables the unit, as well as the analog
camera that is connected to it, to receive power through the same cable as for data
transmission. This makes for easy installation since no power outlet is needed.
•Audio support and USB port
The VK2-ENCODER also supports two-way audio and has an USB port for local recording or
system upgrade.
•Improved Security

camera. Depending on operation methods, it is possible to connect an alarm cable or audio
cable additionally. For its fixation on different locations, please consult with an installer.
Network Connection
The VK2-ENCODER supports the operation through the network. Therefore, it is necessary
to connect a standard RJ-45 cable to it. Generally a cross-over cable is used for directly
connection to PC, while a direct cable is used for connection to a hub.
IP Assignment
When a camera, Encoder or Decoder is first connected to the network it has no IP address.
So, it is necessary to allocate an IP address to the device with the “Smart Manager” utility
on the CD.
1. Connect the VK2-ENCODER / device to the network and power up.
2. Start Smart Manager utility (All Programs>SmartManager>SmartManager), the main
window will be displayed, after a short while any network devices connected to the
network will be displayed in the list.

3. Select the VK2-ENCODER on the list and click the right button of the mouse. You can
see the popup menu as below.
4. Selecting the “Assign IP” in the popup menu displays the following window. Enter a
proper IP address and click the OK button.
The description of each field for the connection in the SmartManager window status follows.
: Available for connection to the camera
: Loading settings information of video after connecting the camera.
: Connectable to the camera but fixed security settings (password)
: Unavailable for connection to the camera (PC can not access relevant IP Address)
Note: For more information, refer to the Smart Manger User‟s Manual.

3. Operation
The VK2-ENCODER can be used with most standard operating systems and browsers.
Notes: To view streaming video in Microsoft Internet Explorer, set your browser to allow
ActiveX controls.

3.2. Access from the internet
Access from the internet Once connected, the VK2-ENCODER is accessible on your local
network (LAN). To access the video encoder from the Internet you must configure your
broadband router to allow incoming data traffic to the video encoder. To do this, enable the
NAT-traversal feature, which will attempt to automatically configure the router to allow
access to the video encoder. This is enabled from Setup>System>Network>NAT.
For more information, please see NAT traversal (port mapping) for IPv4, on page 46.
3.3 Setting the admin password over a secure connection
To gain access to the product, the password for the default administrator user must be set.
This is done in the “Admin Password”dialog, which is displayed when the VK2-ENCODER is
accessed for the setup at the first time. Enter your admin name and password, set by the
administrator.
To prevent network eavesdropping when setting the admin password, this can be done via
an encrypted HTTPS connection, which requires an HTTPS certificate (see note below).
To set the password via a standard HTTP connection, enter it directly in the first dialog
shown below. To set the password via an encrypted HTTPS connection, see Setup>System
>Security>HTTPS, on page 40.
Note:
HTTPS (Hypertext Transfer Protocol over SSL) is a protocol used to encrypt the traffic
between web browsers and servers. The HTTPS certificate controls the encrypted exchange
of information. The default administrator user cannot be deleted. If the password for admin
is lost or forgotten, the video encoder must be reset to the factory default settings. See
page 56.

and the properties of your network will determine the type you use.
The Live View page in the video encoder provides access to H.264, MPEG-4 and Motion JPEG video
streams, and to the list of available video streams. Other applications and clients can also access
these video streams/images directly, without going via the Live View page.

3.5 Setup
This section describes how to configure the VK2-ENCODER, and is intended for product
Administrators, who have unrestricted access to all the Setup tools; and Operators, who
have access to the settings for Basic, Live View, Video & Image, Audio, Event, and System
Configuration.
You can configure the VK2-ENCODER by clicking Setup in the top right-hand corner of the
Live View page. Click on this page to access the online help that explains the setup tools.
When accessing the VK2-ENCODER for the first time, the “Admin Password” dialog appears.
Enter your admin name and password, set by the administrator.
If the password is lost, the video encoder must be reset to the factory default settings. See
Resetting to the Factory Default Settings, on page 56.

3.5.1 Basic Configuration
3.5.1.1 Users
User access control is enabled by default. An administrator can set up other users, by giving
these user names and passwords. It is also possible to allow anonymous viewer login,
which means that anybody may access the Live View page, as described below:
The user list displays the authorized users and user groups (levels):
User Group
Authority
Guest
Provides the lowest level of access, which only allows access to the
Live View page.
Operator
An operator can view the Live View page, create and modify events,
and adjust certain other settings. Operators have no access to
System Options.
Administrator
An administrator has unrestricted access to the Setup tools and can
determine the registration of all other users.

3.5.1.2 Network
The VK2-ENCODER support both IP version 4 and IP version 6. Both versions may be
enabled simultaneously, and at least one version must always be enabled. When using IPv4,
the IP address for the video encoder can be set automatically via DHCP, or a static IP
address can be set manually. If IPv6 is enabled, the video encoders receive an IP address
according to the configuration in the network router. There is also the option of using the
Internet Dynamic DNS Service. For more information on setting the IP address, please see
Setup> System>Security>Network.
•Obtain IP address via DHCP - Dynamic Host Configuration Protocol (DHCP) is a protocol
that lets network administrators centrally manage and automate the assignment of IP
addresses on a network. DHCP is enabled by default. Although a DHCP server is mostly
used to set an IP address dynamically, it is also possible to use it to set a static, known IP
address for a particular MAC address.
•Use the following IP address - To use a static IP address for the VK2-ENCODER,
check the radio button and then make the following settings:
-. IP address - Specify a unique IP address for your VK2-ENCODER.
-. Subnet mask - Specify the mask for the subnet the VK2-ENCODER is located on.
-. Default router - Specify the IP address of the default router (gateway) used for
connecting devices attached to different networks and network segments.

Note:
DHCP should only be enabled if using dynamic IP address notification (see below), or if
your DHCP server can update a DNS server, which then allows you to access the VK2-
ENCODER by name (host name). If DHCP is enabled and you cannot access the unit, you
may have to reset it to the factory default settings and then perform the installation again.
Notes:
-. The ARP/Ping service is automatically disabled two minutes after the unit is started, or
as soon as an IP address is set.
-. Pinging the unit is still possible when this service is disabled.
3.5.1.3 Video & Image
• Video Setting
-. Codec
The codec settings are separated into MPEG4 and H.264.
H.264 is also known as MPEG-4 Part 10. This is the new generation compression standard for
digital video. This function offers higher video resolution than Motion JPEG or MPEG-4 at the same
bit rate and bandwidth, or the same quality video at a lower bit rate.
-. Profile

There are 4 pre-programmed stream profiles available for quick set-up.
Choose the form of video encoding you wish to use from the drop-down list:
* H.264 MP(Main Profile):
Primarily for low-cost applications that requires additional error robustness, this profile
is used rarely in videoconferencing and mobile applications, it does add additional error
resilience tools to the Constrained Baseline Profile. The importance of this profile is
fading after the Constrained Baseline Profile has been defined.
* H.264 BP(Base Profile):
Originally intended as the mainstream consumer profile for broadcast and storage
applications, the importance of this profile faded when the High profile was developed
for those applications.
* MPEG4 SP(Simple Profile):
Mostly aimed for use in situations where low bit rate and low resolution are mandated
by other conditions of the applications, like network bandwidth, device size etc.
* MPEG4 ASP(Advanced Simple Profile):
Its notable technical features relative to the Simple Profile, which is roughly similar to
H.263, including "MPEG"-style quantization, interlaced video, B pictures (also known as
B Frames), Quarter Pixel motion compensation (Qpel), Global motion compensation
(GMC).
-. Resolution
It enables users to determine a basic screen size when having an access through the Web
Browser or PC program. The screen size control comes in seven modes like
4CIF(704x480), 2CIF(704x240), CIF(352x240), QCIF(176x120), VGA(640x480),
QVGA(320x240), and QQVGA(160x120). Users can reset the selected screen size anytime
while monitoring the screen on a real-time basis.
-. Bitrate control
Limiting the maximum bit rate helps control the bandwidth used by the H.264 or MPEG-4
video stream. Leaving the Maximum bit rate as unlimited maintains consistently good
image quality but increases bandwidth usage when there is more activity in the image.
Limiting the bit rate to a defined value prevents excessive bandwidth usage, but images
are lost when the limit is exceeded.
Note that the maximum bit rate can be used for both variable and constant bit rates.
The bitrate can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts
the bit rate according to the image complexity, using up bandwidth for increased activity
in the image, and less for lower activity in the monitored area.
CBR allows you to set a fixed target bitrate that consumes a predictable amount of
bandwidth. As the bit rate would usually need to increase for increased image activity,
but in this case cannot, the frame rate and image quality are affected negatively. To
partly compensate for this, it is possible to prioritize either the frame rate or the image
quality whenever the bit rate needs to be increased. Not setting a priority means the
frame rate and image quality are equally affected.

-. Compression
When it is necessary to adjust a smooth transmission status according to network
situations, users can increase the compressibility to carry out the network transmission
stably. On the other hand, when it is necessary to maintain a detailed monitoring screen
by enhancing the image quality, users can do so by decreasing the compressibility. In
ease case, please adjust this function according to the network status and monitoring
purposes. The default is 2000(Kbps).
-. Framerate
Upon the real-time play, users should select a frame refresh rate per second. If the rate is
high, the image will become smooth. On the other hand, if the rate is low, the image will
not be natural but it can reduce a network load.
-. GOP size
Select the GOP(Group of Picture) size. If users want to have a high quality of fast image
one by one, please decrease the value. For the purpose of general monitoring, please do
not change a basic value. Such act may cause a problem to the system performance. For
the details of GOP setting, please contact the service center.
• Image Setting
Sometimes the image size is large due to low light or complex scenery. Adjusting the
frame rate and quality helps to control the bandwidth and storage used by the Motion
JPEG video stream in these situations. Limiting the frame rate and quality optimizes
bandwidth and storage usage, but may give poor image quality. To prevent increased
bandwidth and storage usage, the Resolution, Frame rate, and Frame Quality should be
set to an optimal value.
-. JPEG resolution
Same as the video settings.
-. JPEG framerate
Same as the video settings.
-. JPEG quality
Select the picture quality. If users want to have a high quality of fast image one by one,
please decrease the value. For the purpose of general monitoring, please do not change a
basic value. Such act may cause a problem to the system performance.
When satisfied with the settings, click Save, or click Reset to revert to previously saved
settings.

3.5.1.4 Audio
The VK2-ENCODER can transmit audio to other clients using an external microphone and
can play audio received from other clients by attaching a speaker. The Setup page has an
additional menu item called Audio, which allows different audio configurations, such as, full
duplex, and simplex.
• Audio Setting
-. Enable audio
Check the box to enable audio in the video stream.
-. Compression type
Select the desired audio Compression format, G726.
-. Sample rate
Select the required Sample rate (number of times per second the sound is sampled). The
higher the sample rate, the better the audio quality and the greater the bandwidth
required.
-. Sound bitrate
Depending on the selected encoding, set the desired audio quality (bitrate). The settings
affect the available bandwidth and the required audio quality.
• Audio Input
Audio from an external line source can be connected to the Line/Mic in jack of the VK2-
