Development of
network cameras has more than 10 years,only the last stage of IP cameras
are in low resolution , and its applications are unsatisfactory. In the
security industry,generally considered high-definition IP cameras in
the security market really knocked the door into the industry IP
cameras,IP cameras makes them really coming into view.HD IP cameras has its inevitable emergence of factors:One is the rapid development in
recent years, the security industry to promote technological progress ,
the demand point of market changes, users seek clearer video
effect;second is networking and information technology the rapid
development of affected industries;Third, the security industry 's chip
technology and software technology to achieve a higher level ; fourth
point is the IP cameras has a more traditional analog relative
advantage,it breaks through the traditional analog control can not be
achieved height. Of course, there is no lack of other key factors have
contributed to the rapid development of the IP cameras,IP cameras will
develop but how and to what height?Whether it will dominate the future
of video surveillance market?These require validation of the market.
Currently
, HD IP cameras market is in a stage of rapid development , as the
financial , transportation and other industries expansion, organizing
major international events , safe city construction , smart city
construction projects demand for high -definition monitor , which
greatly promoted the HD IP cameras development. From the definition ,
the analog camera is close to the limit, in a short time there is no
room for improvement. In traditional monitoring system, watch the video
file transfer monitoring system is to use the most important part , but
often is not high definition video files , the overall picture looks
blurred , especially the face and other details see clear enough to
monitor this the practical effect of playing a big discount . With the
emphasis on the social aspects of security monitoring and traffic
throughout the city , such as security monitoring , installation is also
increasing the number of cameras , how to effectively monitor and
manage is currently facing a major problem. HD IP cameras appeared just
to solve this problem , it can not only provide high-definition video
effects , with the traditional analog surveillance incomparable
advantages in network monitoring and value-added features.Today,HD IP
cameras on many projects have been widely used , such as in airports,
high-speed rail , urban traffic monitoring sites , banks , shopping
malls can be seen high demand for HD IP cameras figure. We found that
the current application of IP cameras is no longer confined to the core
cities and coastal areas , is no longer confined to high-end market and
industry-specific . Meanwhile, with the increasing demand for
high-definition monitor,the number of industry players also surged , but
relatively concentrated geographical distribution , mainly in Shenzhen
and Guangzhou , the Yangtze River Delta , Hangzhou , Shanghai and Suzhou
and Tianjin, north China 's Pearl River Delta region . These regions
occupy the vast majority of domestic well-known security vendors such as APEXIS, they
accumulated over the years in the security industry, product
development, production and sales experience in the overall promotion of
the rapid development of network cameras play a crucial role.
With
the rapid development of computer and network transmission technology
and image processing technology, video surveillance is undergoing a
transformation. Meanwhile, under the strong market demand and promote
innovative technologies involving IP cameras technology layer and
application layer in the last two years gained rapid development. High
resolution high resolution HD IP cameras is a direct advantage , since
the definition monitor swept through the security industry since the
resolution of the recording often seems to be refreshed. Today, the
monitoring front-end HD 720P, 1080P is already common, 3,000,000 pixels ,
5 megapixel HD IP cameras also has a certain market share . In 2013 , Shenzhen CPSE meeting , the
industry a few manufacturers have introduced several image sensors up
to do pixel-level image sensor , and as supporting the lens
manufacturers , which do pixel-level ultra-high definition lenses are
also several models , this means that in the near future, millions of
pixels of ultra- high-definition IP cameras may appear in the security
industry . Currently, the mainstream MPEG compression algorithm and
H.264. The former requires only under specific format to use , but its
bandwidth will bring more pressure, and H.264 in MPEG compression
capacity than doubled , they are able to achieve higher compression
ratio. However, with the continuous improvement IP cameras HD resolution
, stream bandwidth and storage increasing pressure , the industry needs
more high-performance compression algorithm. H.264 HIGH PROFILE
compared to the first generation of H.264, but also enhance the
performance doubled IP cameras mainstream manufacturers are now using
this algorithm for video compression. However , H.265 algorithm is a
representative of the new technology, we can improve the compression
efficiency and reduce delay , transmission speed can be achieved using
1-2Mbps transmission 1080P quality. This also means that the smart phone
, tablet and other mobile devices will be able to direct online play
1080P full HD video. Functional morphology IP cameras products more
abundant compared to traditional products , which can bring more added
value for the user , the camera manufacturers will integrate a rich and
useful features in the respective IP cameras products, in order to
attract more users. If APEXIS HD infrared bolt , which not only built a
multi-stream technology, making the front of the device can output a
variety of different streams for different devices to watch, also
provides electronic image stabilization modes and corridors , as well as
into the lens fog function, so the camera can be timely in harsh
environments get a clear image.
Intelligent video surveillance
is digital, network -based video surveillance , but is different from
the general network video surveillance , it is a higher-end video
surveillance applications. Intelligent video surveillance system can
effectively utilize and expand the use of video resources ,
automatically identify different objects found anomalies in the monitor
screen , and can be the fastest and best way to alert and provide useful
information , which can be more effectively assist security personnel
to deal with the crisis and minimize the false positive and false
negative phenomenon . Today , IP cameras 's intelligent video analysis
to be applied gradually , many camera manufacturers of high-end products
will be integrated into the corresponding IP cameras intelligent video
analysis. Currently, the mainstream security market intelligence and
analysis capabilities with video cover video loss detection, people
counting entrances , articles legacy recognition , intrusion
identification, video motion detection, identification, and so the crowd
movement and congestion.Intelligent cameras can identify from complex
data analysis and types of behavior , providing command , data and
information , in order to achieve alarm to alert attention, intelligent
retrieval intelligent behavior . Meanwhile, the smart device to
selectively transmit video , thus saving bandwidth , greatly enhancing
the available network bandwidth. Intelligent monitoring surveillance
technology has become an important development and market demand theme .
3G, 4G mobile data network deployment of the wireless network as a
video image carrier as possible, especially nowadays telecom operators
to promote the 4G network , the maximum speed can reach 100Mbps, fully
meet the current definition of IP cameras communication bandwidth ,
mobile video surveillance is the future an important direction of
development. Mobile video surveillance so that the original fixed -based
video surveillance gradual transition to a distributed mobile video
surveillance , such as the subway , rail , bus and other industries,
thereby breaking the original video surveillance is limited to the
geographical , technical , cost, etc. , so that the business
applications audience expanded. Families and civilian development is
very rapid video surveillance because it contains a huge opportunity. In
the past, people did not excessive security consciousness, which has a
great relationship with the prevailing economic conditions , advanced
network infrastructure and equipment and other factors . Today, even the
definition of IP cameras price for ordinary home users are exposed to
within the range , and high-definition IP civilian products P2P Plug and
Play, automatic penetrate multilayer routing , no IP domain
configuration, adaptive network , straightforward features such as
support for multi-terminal system monitoring , making installation
easier, just follow the simple instructions manual can be installed .
The future of video surveillance market will continue to be family
oriented, civilian -oriented development , 3G, 4G is a high-end video
surveillance and differentiated characteristics typical of multimedia
services , both professional emergency services in the areas of command,
the bus monitor , also can be used as an ordinary consumer , into the
home monitoring, public multimedia services and other fields. Moreover,
the current high-speed network support WiFi everywhere will greatly
promote civilian security process. With the rapid development of science
and technology , security has gradually entered the era of the entire
network security monitoring market, and network cameras throughout the
network video surveillance market as the core device,no doubt,HD IP
cameras application and development on behalf of the entire network
video surveillance and future trends.At the same time as the current FN
video surveillance industry,IP cameras is gradually adapt to the diverse
needs of the current market demand and future market development.
