Network video monitoring system in the implementation process, the universal
existence two typical problems: one is the insufficiency of network resources,
how to use limited bandwidth important data transmission, The second is the old,
old analog matrix monitoring system how to recycle. In this situation, the
construction model to solve these problems effectively, the manufacturers and
users are the focus of concern.
As well-known overall solutions provider, combined with the construction
of practical project, and great experience that adopting network video
monitoring system and matrix system combines video surveillance system is more
comprehensive model can effectively solve the above two contradictions. Through
the analysis of existing successful cases, we will summarize and network video
monitoring system and matrix combined application of the system for four typical
pattern: DVS mode, matrix switchers mode, D + M model and network matrix model,
in the same project construction, these four modes can coexist and can access
the same platform.
1 and DVS mode
This model can understand the network video monitoring for regular pattern
of network video monitoring, front-end web video server device, such as video
input analog camera (by), network video camera, network direct access monitoring
network ball (LAN/WAN). This pattern has construction simple, convenient and
flexible management of distribution characteristics. In the construction of new
monitoring, especially suitable for this approach in most city security,
intelligent community monitoring, campus and monitoring program in this way to a
new or extension of monitoring system.
At the same time as video surveillance network and great in r&d of matrix
and DVR system with many advantages, such as: virtual matrix element, more
complicated, PPPoE, DDNS RTSP, FTP, etc, in practical application, and the cause
of a network video monitoring device for each has played a small video monitor
host of comprehensive, whether the audio, video, regular alarm data or other
special occasions detection data (temperature, current and voltage, etc.), can
access network video monitoring equipment, through the network transmission in
direct call again after processing, thus make or video monitoring design and
construction become simple than ever before.
2 and matrix switchers mode
Matrix switchers and great was launched one of the concept of new
products, product support > (8) from input, coding functions, can be certain of
selective way (remote switching selection of video coding) and through the
network transmission to compress the remote machine, also can not fair after in
the equipment of video data storage medium will expand in local stores.
Especially suitable for application in the network bandwidth resources shortage
in the occasions: monitor and command center adopts the local store, fast
response, data storage complete. In the superior command center through the
network of real-time video calls and basic data storage, low cost, flexible and
convenient. This equipment is fully consider customer requirements, with strong
matrix and network monitoring technology development of market new products
generated.
3, D + M mode
Network video server and matrix model, applications mainly concentrated in
the old, old system upgrading. In video networking control project construction,
if the original old part of the simulation system, using this model matrix can
maximize the use of equipment and save cost.
In this mode, we need some network video server (increased) plug-in or
independent part of the matrix, the simulation output video server access&edge
network video input, utilization of serial data communication, can realize the
original simulation system of digital and networked upgraded. The special is,
because at present domestic various types of matrix control protocol does not
realize thorough standardization, cause a lot of manufacturers and other
manufacturers of matrix network video server cannot smooth communication, this
paper, and the network video server in particular great introduction of
transparent communications channel key technology, using this technology, which
can realize the basic with different manufacturers of matrix system seamless
docking. In practical engineering application, use this key technology, and has
been successfully assist customers to solve achieves the old system upgrade of
communication and compatibility problem in engineering and party a can save them
a lot of product cost and expenses.
4 and network matrix model
We often hear of network matrix this concept, which can realize from the
function can be divided into two classes: first, those can be called network
(set) matrix, through the network can be set and control, video still use fiber,
this kind of matrix in the mass matrix of the construction of cascade systems,
the obvious advantages
In all, the control of node set of communication through information
network, make whole construction simpler, more scope of communication can also
cause, and the TC - 880 series new matrix system is very good representative,
The second network matrix is not only can be realized through the network
control, communications, such information can remote video call several road in
front of the class, but it won't use commonly in pure matrix of the simulation
system, most of the cascade of application or focused on the discussion of the
comprehensive application system, this kind of matrix and the typical
representative of TC is great - 8700 - N series network matrix. In this paper
the network matrix generally refers to mention the second mode.
Network is generally in the new matrix of the monitoring system, and the
matrix switchers, network matrix has more common, and his input analog video
output, can be in local construction of large-scale simulation monitoring
center. According to the actual demand, the user can freely choose the type of
network video module of blade quantity and without additional configuration and
Settings. With TC - 8700 - for example, if the customer N4 only through the
network upload images, no.4, only need a network video module, if only 8 upload
video module can increase a network, and so forth.
Front through this four typical data access network video mode will later,
the client can cause by the network and unified integrated management platform
to achieve in front of all the equipment management, including: DVS and matrix
switchers, network matrix, etc. For users, once the system configuration, will
no longer need to care about what is in front of the building, because all
access model of the interface is the only IP address.
Through the above analysis, we can find that, using the integrated access
system is completely model construction of building in the network frame, and is
the combination of analog and digital, give full play to network transmission
characteristic of flexible, convenient, and ensure the local monitoring of
real-time. In the old system upgrading, using the integrated access mode can
save cost.
