The i-linxI I series IP video management system is an advanced suite of
network appliances and software
designed to provide high quality
delivery and processing of video,
audio, control and sensor data using
standard ethernet based networks.
With a wide range of products to
select from, i-linxI I can be used for
solving the very simple, to the
extremely complex IP video system
i-linxI I solutions are built from three
series of products, consisting of the
9900/9910 Series encoder/decoder
appliances and accessories, the 9950
Series network video archiving and
storage systems, and the 9990 Series
video management software suite.
i-linxI I provides cost effective solutions with seamless integration of
common surveillance and control
functions, including video matrix
switching and camera control, two
way audio communication, alarm point
monitoring and output control,
video/audio recording and archive
management, and 3rd party system
i-linxI I systems begin with the 9900
Series. This line consists of a selection
of MPEG2 or
MPEG4 video encoders and
decoders, providing the connections
for analog video, camera control data,
bi-directional audio, sensor inputs and
control system outputs. All signals are
efficiently compressed and encoded,
and delivered onto the network for
processing and control by i-linxI I 9990
and 9950 Series products.
When recorded video documentation is required, the i-linxI I 9950 Series
NVR systems can be attached to the
network and record any, or all
encoded video and audio streams
directly from the network.
For operator interface and system
management, the i-linxI I 9990 Series
software suite provides the solutions.
The 9990 Series server module provides the i-linxI I framework and database for simple configuration and
device set-up for the system. The
9990 Series GUI module provides
operator interface using easy-tounderstand icons, placed on graphical
site maps of the monitored areas.
System operations can be automatic,
event driven via pre-defined scenarios
or manually controlled.
9900/9100 Series
i-linxII IP video encoder/decoder systems
with HDD slot, along with various capacity
hard disk drive options to choose from.
When video decoding capability is
needed, the single input versions can be
configured as either a single input encoder
or a single output decoder during system
All 9900 Series video appliances are
equipped with a variety of interfaces as
standard features.
These interfaces include one USB port,
three serial communication ports, one bidirectional audio channel, two sensor
inputs, two trigger outputs, one 10/100
baseT Ethernet connection, and of course,
at least one video input.
The three serial communication ports
consist of two RS232 and one RS422
type. Each port is independently configurable for baud rate, data bits, stop bits,
parity and handshake settings.
An encoder and decoder connection
can be established to create a transparent
serial connection across a network,
allowing serial communication devices to
be interconnected.
Each 9900 Series video appliance when
configured as an encoder, provides two
independent video streams, allowing
unique configurations of video resolution,
streaming mode, bit rate, frame rate, GOP
and image settings, providing unmatched
flexibility for optimizing viewing, recording
and network bandwidth utilization.
The 9900 Series video appliances can
be configured to simulate analog switching
functions, using the network cabling infrastructure.
By use of the 9990 Series video management software, 9900 Series encoders
and decoders can be connected to display any camera site on any monitor.
Adding additional camera sites or monitors to the system only requires a network
connection between the camera site and
The Cohu 9900 i-linx I I provides a wide
variety of configuration options for meeting
the most demanding application requirements.
Options include single, dual or quad
video inputs, standard or TS2 operating
temperature ranges, surface mount,
blade/cardcage mount, or surface mount
the decoder, minimizing the costly expansion costs and complexities common in
analog matrix switching systems.
All 9900 Series applicances include an
intergrated web server, allowing viewing,
camera PTZ control and network setting
management using a convetnional web
browser (activeX support required).
Password protection is used to prevent
unauthorized access to the 9900 Series
When wide operating temperatures are
encountered, the 9900 series provides a
TS2-compliant temperature range option
(-34C to +74C ) to insure continuous and
reliable operation in extreme environment
The 9900 can optionally be fitted with a
hard disk drive, allowing camera site video
to be recorded without streaming to an
NVR, thus saving network bandwidth.
The recorded video can be viewed
directly from the camera site encoder, or
downloaded for later viewing.
