Several factors affect the development of intelligent HD IP Camera

Several factors affect the development of intelligent HD IP Camera
Today, our intelligent HD IP Camera is now in the early stage of development, following this stage intelligent HD IP Camera problems encountered in the development of, for profiling.
One problem: the product line and supporting
In order to meet the needs of different projects, the introduction of various characteristics and varieties of a full range of digital video HD IP Camera, we must master the key technology of the camera, that is auto exposure, intelligent HD IP Camera application and popularity of camera series with facilities complete, auto white balance, auto-focus.
Intelligent high-definition monitor the back end the equipment PDVR (or NVR), hybrid DVR geometric traditional DVR technology threshold is a lot higher, requiring higher VGA output resolution and higher decoding and processing performance, the hardware structure than traditional DVR a lot of complex domestic only a small part of DVR manufacturers can successfully make the back end of the smart high-definition video equipment.

Question two: Price
Price, some domestic companies to master the core technology of digital HD IP Camera, digital high-definition Network Camera localization, the price is cheaper than before to buy foreign agents. The price of high-definition Network Cameracloser and closer to traditional analog cameras, so that more users can afford smart HD.
Normally be required on some high-end smart high-definition monitor video wall, smart HD on the wall instead of using matrix or decoder card and decoder box, smart HD special decoding device on the wall. Because high-definition LCD monitor resolution is generally up to 1080P, therefore, an urgent need for video display front-end video equipment to match, parties make HD monitor to play to the best value, or traditional D1, it is greatly wasted HD LCD Monitor HD effect. The lens, smart HD IP Camera optional space is too small, and the price is more expensive, but also affect the rapid spread of high-definition intelligent.
Countries are vigorously promoting the use and development of the Internet of Things technology, the basic idea is "connected to Experience China", which is "more comprehensive and thorough perception, more comprehensive interoperability, smarter decisions. HD Network Camera video, and direct access to the Internet, will in the Internet of Things, a more ambitious role to play in the next generation of Internet applications.

HD IP Camera technology trends

HD IP Camera technology trends
The development of national surveillance market surveillance market in the development process, network monitoring is not meat and potatoes, mainly because, compared with the preaching of analog products, network monitoring technology is not very obvious advantages. Want to use networked video surveillance to win the market, we must vigorously develop the high-definition technology and solve problems that limit their development. In recent years due to the technical reserves of Network Camera and network facilities in perfect, high-definition IP Camera has improved significantly. HD IP Camera in the future there will be what kind of technology trends?
Let's work together to explore.
     1.COMS gradually replace the CCD
     CMOS sensor response speed faster than CCD, CMOS sensor performance is improved rapidly. Therefore more suitable for high-definition monitor large amount of data features.
     2, the resolution is to continuously improve
     Market IP Camera resolution of 1.3 million pixels, 200 pixels, 300 pixels to 500 million pixels, 800 million pixels, even as tens of millions of pixels also began to emerge. So the resolution is demanding higher standards.
     3, standardization
     Whether it is the standard ONVIF or PSIA, are business organizations of their own. The next few years, standardization will become a high-definition Network Camera to the market permits.
     4 ISP by encoding chip integration
     Integrated ISP, not only can significantly reduce system costs more greatly enhanced the stability of the video, optimize the image in optical performance. For enhancing the image quality of high-definition IP Camera has its important role.
     5 more practical, intelligent analysis
     HD IP Camera has been achieved or are achieving intelligent analysis capabilities: video blind and video loss detection, video change detection, the fuzzy video detection, video motion detection, statistics in the number of entrances and exits, crowd movement and congestion recognition items left over recognition, intrusion identification, and so on. Intelligent analysis capabilities than in the past, these functions appear to be "inferior" much, but more practical.

The disadvantage of the HD IP Camera

The disadvantage of the HD IP Camera
HD monitoring time has come, HD IP Camera almost become the mainstream surveillance products, does not know that HD IP Camera has its unavoidable shortcomings.
      
The first is bandwidth usage. 1080P HD IP Camera, 5 times the amount of information D1 camera, the optimized encoding compression, bandwidth usage about 2M, higher than the D1 Network Camera more than doubled. If the internal network is also not a big problem, but the long-distance transmission, you have to use the line, ADSL is not good enough.
      
The second is occupied by the large memory capacity. 2M stream, each image per hour to be occupied by the 0.9G space, the same higher than D1 Network Cameras, more than doubled.
      
Again is demanding on the computer, because the decoding of high-definition images to spend more CPU resources, decoding a HD Network Camera, roughly equivalent to the decoding four SD Network Cameras.
    
In addition, some high-definition IP Camera illumination is less than standard definition. Here mainly refers to most of the CMOS HD products, but this problem has been a significant improvement in, and before long, this problem does not exist. CCD high-definition Network Camera does not exist the problem of illumination, but the cost is too high, it is still CMOS for mainstream products.
      
In summary, storage, computer requirements, which can be ignored only increase the cost of a little. Bandwidth problems, not a problem in a local area network (LAN), wide area network or a major obstacle. Illumination problem is solved step by step, indoor use infrared light to basically solve the long-range view of the scene outdoors, then use the CCD HD Network Cameras as well.
      
Even HD IP Camera these shortcomings, but we still have a lot of ways to circumvent some of the problems such as bandwidth, even if there is not a good solution, but to the development point of view, it will certainly be solved. At first our computers to 1M of memory, at least 1G. The speed of development of science and technology can be seen far beyond our imagination. Friends, with the development of the attitude towards the new things, the courage to do the beach-goers of the times!

The present situation and development trend of the surveillance cameras

The present situation and development trend of the surveillance cameras
With the development of the entire security market network, digitization, and manufacturers of technical progress in the digital processing, Network Camera situation gradually be opened in the fast growing market demand, resulting in the traditional analog control system market share slightly downward trend . Despite the the digital surveillance momentum so ferocious, network monitoring business in the country's overall security market share is still limited, and monitor the development of the market network monitoring is not yet mature about, plus analog surveillance products in terms of technology, application or the overall control system architecture has been very mature, so in recent years, although the network monitoring market in high-speed growth, but the market share of traditional analog surveillance products is relatively stable.

Network Camera market situation
Step by step, along with the trend of global digital technology, network security industry continue to transition from analog to digital, network video surveillance has gradually become the darling of the industry. Thanks to the peace-building, the Shanghai World Expo and Guangzhou Asian Games, vigorously promote the development of IP Camera in recent years by leaps and bounds. It is understood that the market share of domestic producers has more than 50%, the size of the market has expanded from 5.2 million in 2008 to about 15 million in 2010, an increase of 200%, which showed that the domestic Network Camera is in a stage of rapid development, and 80% of the people in the industry generally believe that the demand for IP Camera will continue to grow.
The historical data show that in 2008 the domestic Network Camera the size of the market accounted for about 4% of the camera market size in China reached 520 million yuan. 2009, Network Camera market grew by about 100%, the market size of about $ 1 billion. According to sales data provided by the Network Camera manufacturers , as well as various contractors Network Camera purchases, and with reference to the part of the chip manufacturers to provide data statistical analysis: the proportion of camera project application in 2010, analog cameras accounted for 88%, IP Camera accounted for 12% of the latter's share of the market size of $ 1.5 billion. From 2008 to 2010, the market share of IP Camera average growth rate of 70% of the high-speed development. This development momentum is expected to the 2011 domestic Network Camera market is expected to exceed 20 billion mark.
Since 2009, with the financial, transportation and other industries and safe city part of the project, the high demand for high-definition monitor, coupled with the Shanghai World Expo and Guangzhou Asian Games and other major events to promote high-definition monitor trends, HD IP Camera (resolution greater than or equal to 720P) mushroomed rapid growth. Some mainstream network video surveillance manufacturers such as Panasonic, Sony, Hikvision, Kodak, Axis, Dahua, the Yellow River have launched megapixels Network Camera, a new round of competition in the high-definition network surveillance. The survey shows that the HD IP Camera in 2010, the average monthly volume of more than 1 million units shipped throughout the year total more than 20 million units, compared with 2009, an increase of more than 200% of the Network Camera ratio is about 34% . HD IP Camera megapixels 56%, 37% from 200 million pixels, 3,000,000 pixels or more than 7%.

Analog camera market situation
Which the overall surveillance camera applications, the market is mainly divided into analog surveillance market and network monitoring market, analog surveillance products still account for the absolute dominance of analog cameras, after all, after years of development, has become very mature product, the market stabilized. However, the Network Camera market demand showing a blowout situation, analog surveillance cameras market share declined, the market demand has slowed. According to the survey, in 2008, the highest market share of analog cameras about 90% in 2009, down 5 percentage points to about 85%, 2010 HD the first year, millions of digital high-definition cameras began rapid growth in the years analog cameras market share dropped to 75%, the survey data from January to May this year can be expected that the share of the analog cameras this year will fall to about 60-65%, from the data show that the analog camera market share in the next few years will be reduced to 50%.
Epilogue
With the continuous development of digital network technology, digital video surveillance will inevitably become the future mainstream monitoring, Network Camera market size will be tremendous growth. But also from the the big action point of view of the major mainstream camera manufacturers, IP Camera gradually HD, it also means that high-definition digital video surveillance has also been totally cut - the door opened higher. This strong consistency with the development of digital television: from SD to HD, the pursuit of full HD. This is not just users of the requirements of the sharpness of the image, is also related to the high demand of some professional place of image detail. 2010 Shanghai World Expo, high-definition monitor outlets huge capital investment is just a booster, let us understand high-definition monitor is not a concept, but a full development of new monitoring direction.

The HD network monitoring FAQs and response options

The HD network monitoring FAQs and response options
Compared to SD video surveillance, high-definition network surveillance advantages are clear, but more than two years of marketing, will inevitably encounter the following types of issues:
1, the transmission
HD IP Camera will generally choose 720P or 1080P solution, if you want to achieve the desired image, you need to 8M of network bandwidth, if a system which have hundreds of points, and that the entire network data stream will be considerable and video streams real-time data streams, will continue to cause a steady pressure to the network switching equipment, which requires network planning to do plenty of homework.
2, storage
On a question referred to the problem of huge data stream, data aggregation to the center of each node is stored, the pressure on the entrance of the center bandwidth and storage capacity is a big challenge.
3, shows the aspect
Numerous high-quality manufacturers only focus on the front of the camera pixels, without the research and development of high-definition video decoder, only around a PC screen to watch high-definition image, can not be independent HD images on the big screen on the display.
4, the management
HD manufacturers or done in accordance with the ideas of the traditional analog cameras HD IP Camera, bought off-the-shelf hardware solutions provided by third parties MPEG4 standard algorithm, only provides a network interface, simple digitized As for the back platform how to IP Camera hardware and data flow management, not the bottom of the core algorithms and technology, simply can not be achieved.
5, the night
HD lit during the day, is a very easy thing, Once the application in low light or night surveillance is required when HD became a hero with no useless. Since most of the high-definition IP Camera CMOS sensor, low light sensitivity, if not with the infrared light, the night is dark, and we monitor the most to prevent precisely the time period is at night, so it will make the high expectations of high-definition video systems has become a decoration.
Fanaticism behind in our HD products, it should be more sober analysis of the actual problem, how to solve every problem, which is many small manufacturers to consider their concerns are often confined to a certain product itself pixels high, that is, high-definition, high-end system solutions. Solutions only feasible theory, you can not really go in the actual project implementation. Some even only has a 1.3-megapixel front-end processing software, shocked to increase to 300 million or 400 million pixels.
In the project continue to practice and explore Science and Technology Co., Ltd. of Shenzhen City Granville as the dot-com for the five problems and put forward effective solutions in the application has been made so that the majority of users satisfied with the results.
Transmission
Continue to reduce the cost of fiber optic cable, local area network can be composed of a high-speed network using optical fiber plus a high-performance switch, Gigabit to the desktop is very easy to do. With the popularity of broadband networks, especially the "triple play" just launched this year, the rate of households have reached tens of megabytes to hundreds of megabytes light into the copper ultimately brought us cheap high-speed Internet. For remote high-definition video transmission that do not require too long a time.
Storage problems
Only do a large amount of money invested in IPSAN and storage media IPSAN the best use of embedded architecture, the patch board a lot less, high stability, but the drawback is the poor compatibility, secondary development is not very flexible. NVR products on the market are mostly based on X86 architecture, server plus array card, and put on the application software, server and disk array combo, better compatibility. If way of IPSAN, storage media you need enterprise-class hard drive, so as to to play a IPSAN the advantage of the speed of data storage and security. If you save time does not require too long for some small and medium-sized systems, data security requirements are not too high, can use the mainstream server market to complete the function of the storage.
Display of
HD input interface for high-definition screen TV wall, we have developed a high-definition decoder, the front-end transmission over high-definition graphics effectively restore connection to the big screen, high-definition picture perfect to show on the screen above.
Management
Try to select with the the rich hardware interface front-end equipment, such as alarm, SD card, intercom, audio, 485, can do projects and programs based on the requirements of Party, flexible combination, and no longer need a separate additional customization features. Software have a variety of access methods, such as the WEB client, a large platform can provide the SDK and third-party software can be very flexible docking. Function modules to be as complete as possible, such as alarm, streaming media, storage services, etc., can be directly used in the project.
Night side
We have accumulated a wealth of experience in night vision surveillance and provide different solutions, depending on the environment of the scene. Such as infrared light program, IR Cut technology, low-light chips.
For the first 5 aspects, transmission and storage, system integrators through cost inputs can be solved; display and manage HD manufacturers need to spend some effort to improve the underlying software and hardware; improve night vision effect, the input is relatively small, but also allows the easiest solution to enhance user satisfaction.

the transport protocol combination

the transport protocol combination
     The IP Camera tend applications RTSP, RTP, RTCP, HTTP, UDP, TCP protocol different combinations to transmit real-time audio and video streaming. Common agreement is set out as follows.
    RTP + RTSP protocol combination, this protocol combinations (RTP can use TCP, UDP protocol encapsulation, RTSP TCP protocol encapsulation), real-time audio and video in a normal network environment, you can ensure that the client browser, Network Camera manufacturers often recommend using this protocol combinations. Some network devices often support RTP + RTSP multicast mode.
    RTP / RTSP protocol combination, RTP packet encapsulated into RTSP packets, some network firewalls only allow RTSP protocol packet through. IP Camera also provide real-time audio and video RTP protocol. This combination in no way increases the complexity of the network load and client management system.
    RTP / RTSP / HTTP protocol combinations, an increase in the RTP / RTSP and the data on the basis of the HTTP package, the combination of this Agreement in order to adapt to the network firewall only allows the use of the HTTP protocol network environment. Although the network load is increased, but the Network Camera can be adapted to the more complex Internet environment.
    UDP protocol (TCP), a number of IP Camera in order to adapt to the poor condition of the domestic network bandwidth, there is no use of RTP + RTSP application layer protocol encapsulated audio and video data, the audio and video stream using only UDP or TCP transport layer protocol encapsulation. So that the audio and video stream you can use a small amount of network bandwidth to transmit streaming media. The combination of this Agreement can also provide similar RTP + RTSP Advanced features, but can not use network routing equipment based on RTP + RTSP combination optimization features.
    UDP (TCP) / HTTP protocol combinations, audio and video streaming data encapsulated into HTTP data packet, and then use UDP (TCP) protocol transmitted to the client. This agreement can be adapted to the complexity of the Internet environment, can penetrate most network firewall.
    The combination of a variety of transport layer protocols to ensure the reliability of real-time transmission of audio and video and PTZ data, Network Camera built-in processor computing capacity constraints, resulting in the limited number of concurrent access users. Often can not meet the concurrent access demanding applications, IP Camera often have multicast network transmission equipment in response to more concurrent access requirements. Some IP Camera client software is powerful, data forwarding mechanism to act as can respond more concurrent access to the user's "virtual Network Camera, this approach is adapted to adapt PTZ network camera. Construction of large-scale digital video surveillance network is important.

IP Camera Transfer Protocol Overview

IP Camera Transfer Protocol Overview
the transmission protocol
     Network Camera based on IP network transport protocol, so as to ensure that the audio and video data, PTZ control data network transmission quality. Real-time video streams through IP networks, through multiple protocols portfolio, to adapt to a variety of complex network transmission environment.
    RTP (Realtime Transport Protocol), real-time transport protocol, specifically designed for real-time streaming RTP's basic functions of several real-time data stream is multiplexed into a UDP packet stream, the UDP stream may be sent to a host computer (unicast mode), and can also be sent to multiple target host (multicast mode). RTP packaged as only the conventional UDP, in theory, the router does not have any special treatment group, but now advanced routing device has RTP protocol optimization option. Of RTP timestamp mechanism, not only to reduce the influence of jitter, but also allows multiple data streams between synchronization, so you can easily based on the I / O event video image captions, IP Camera tend to audio and video The encoded data is encapsulated into RTP packets.
    RTCP (Realtime Transport Control Protocol) real-time transmission control protocol, RTP sister agreement, which handles feedback, synchronization and user interface, but does not transmit any data. Its main function is used to provide information about the delay, jitter, bandwidth, congestion and other network characteristics of the feedback information, the encoding process can make full use of such information to the source client. So when network conditions are good, the data rate can be increased (so as to achieve a better quality), and when the network situation is bad, it can reduce the data rate. Continuous feedback coding algorithm can continuously be adjusted accordingly to provide the best possible quality in the current conditions.
    Real Time Streaming Protocol RTSP (Real Time Streaming Protocol), RTSP protocol using the push server (push server), audio and video browsing side, sends a request, IP Camera just kept encapsulated into RTP packets of audio and video to the browser-side push encoded data, IP Camera can be very small overhead of streaming media transmission.
    Hypertext Transfer Protocol HTTP (HyperText Transfer Protocol), Network Camera via the HTTP protocol to provide Web access feature, easily the audio and video data through a complex network transmission, real-time audio and video support is far from ideal.
    Datagram Protocol UDP (User Datagram Protocol), is the most basic network data transfer protocol, IP protocol provides no network connection services, used to encapsulate the a strong network real-time audio and video data, even if the process of network transmission packet loss phenomenon, it will not affect the audio and video browser on the client.
    Transmission Control Protocol TCP (Transmission Control Protocol), IP protocol provides a connection-oriented network service, designed to provide a reliable end-to-end byte stream unreliable Internet. TCP protocol often in the service-side and client-side after several "handshake" to establish a connection, thus using the TCP transport real-time audio and video streaming overhead, if the network is unstable, audio and video jitter phenomenon. Management commands using its reliability is used to transfer the IP Camera, such as PTZ, I / O device control command.

The IP Camera is the ideal platform for intelligent video analysis

The IP Camera is the ideal platform for intelligent video analysis
In the 1990s, led by the Defense Advanced Research Projects Agency of the visual monitoring of major projects VSAM (VisualSurveillanceMonitoring) has attracted the participation of many university research institutions, thus beginning the prelude to the intelligent video analysis technology research and application. So far, the application of intelligent video analysis technology for nearly 20 years, the worldwide deployment of many intelligent analysis system running. But should see the basic intelligent video analysis applications are centralized applications, mostly PC-based applications. With the deployment of network video surveillance system and a number of large-scale monitoring project launched until the last 2,3 years, intelligent analysis system based on embedded devices began to get more attention and application.
Intelligent analysis of high-level applications include regional preparedness, behavior understanding, object recognition, smoke, flame recognition, PTZ tracking, traffic management. Market intelligence analysis application is mostly limited to the area of ​​prevention, intrusion detection, tripwire detection, and other more complex engineering applications is also unusual. On the one hand we believe that intelligence analysis is one of the important direction of development of video surveillance, on the other hand, should also see the intelligent analysis of engineering practice still faces many problems.
The reason is technical reasons, intelligent analysis is absolutely not science, its successful implementation requires a wide range of fit, intelligent analysis technology in the development process; followed by domestic enterprises doing enough in terms of technology accumulation , most OEM foreign companies algorithm, the domestic enterprises to truly master the core algorithm handful algorithm adjustment, it is difficult to make specific scene.
Intelligent analysis technology can be divided in two parts of the underlying modeling and high-level modeling. The underlying modeling including background modeling, target detection, target tracking, feature extraction, such as the basic algorithm, high-level modeling is to be judged according to the preset rules to generate analysis results.
The best equipped platform of intelligent video analysis
The intelligent video surveillance system has just begun the implementation of relevant standards can be based. Coupled with intelligent analysis would have been no standard algorithm, there is no standard indicators, most of the implementation of the project according to the designer's experience and needs of the owners, the system implementation is a matter of opinion.
Intelligent Video Surveillance System with respect to traditional monitoring the most essential difference is that the information to understand and analyze links. Theoretically understanding and analysis can occur at various stages of the data stream, it formed a different intelligent analysis solution. Understanding and analysis of information collected in the distal end unit perform the smart conferred camera, to form a smart camera, and includes analog cameras and IP Camera; understanding and analysis of information is performed in the intermediate unit is formed intelligent DVR devices; understanding and analysis of information of course can also be in the backend The server performs a centralized intelligent monitoring system.
Different solutions have different characteristics, system design requirements are not the same. With respect to the the backend centralized deployment, we think that the front-end processing, distributed processing more competitive, the following reasons: First, the problem of the processing capability. Intelligent analysis requires the image pixel-by-point analysis, a huge amount of computation, when the input video channels more centralized processing processor bandwidth can not support. Distributed processing a single processor capability is not strong, but only handle all the way bandwidth is enough.
Followed by the problem of network bandwidth, the centralized processing need all the video data are transmitted to the server, and distributed processing can be selective transmission according to the analysis result.
Finally, there is the issue of cost distributed processing on the basis of the original hardware without increasing the cost or only very small increase in cost can be realized intelligent analysis of the large ones of the same video is clearly more centralized processing increased costs.
In summary, the IP Camera is the best equipped platform for intelligent video analysis.

E-commerce sales model to explore the establishment of a security IP Camera

E-commerce sales model to explore the establishment of a security IP Camera
      Some products have been trying to e-business models, such as CCTV, DVR, IP Camera, but not all security products are suitable for online sales. Because security products e-commerce biggest drawback is the actual customer experience and after-sales service problems can not be solved, some security products due to the characteristics of its products, requires the existence of pre-planning. Therefore, the need vendors to provide a good user experience to attract customers.
  In addition, I found that some manufacturers just change the sales channels, network sales product packaging, features are 100% consistent. Able to meet customer needs? System in the civil security market has not yet formed, Internet sales of security products, if not end-user demand, whether it will affect the user enthusiasm? Vendors and channels to note that: The product is suitable for the network sales? whether based on the market to customize or modify the upgrade?
  The author believes that do IP Camera security of e-commerce, the following points are essential: professional sales consultants to understand the product, have good communication skills; perfect after-sale mechanisms; supporting rapid logistics support system; complete and effective the supporting marketing system, specializes in microblogging, promotions, and user interaction; systematic user feedback gathering process and the reverse process, from the user, marketing, research and development to further promote a civilian market for security products.
  How to locate the e-commerce business planning security?
  E-commerce operations are independent operations and outsourced operations both by characteristics from the security point of view, whether it is the product technology and after-sales service, outsourced operations relatively difficult, so be sure to independent operators. Security products, alarm products, network video surveillance, independent building visual intercom products are suitable for online sales, but not the entire product line so Do not equated the needs of the needs of end users and contractors, distributors, subtraction should be appropriately targeted modifications in accordance with the civilian market demand the 1-2 product packaging, functionality, configuration, and to adapt to the needs of end users.
  The promotion of e-commerce current popular spike + buy, buy may be a great way to sales growth, in fact, once again into the price war siege. Line and off-line products to fight to the homogenization, there is no profit margin, online continue to fierce price competition, leading into a vicious competition again infinite loop. If this is not as good as do not do e-commerce.
  Future impact on the pattern of traditional security market?
  Development problem is that the security of e-commerce and the traditional channels Contractors conflict, such as price, channel conflict. Reduce these conflicts will make the channel profit, cause serious Chuanhuo. But little impact on the traditional security business model, and not forming due to the Chinese consumer security industry, especially the civilian market, its impact is limited. Consumer security era truly arrived, Internet e-commerce, Internet of Things applications, smart home together to promote.

Security for high-definition monitor the effect is really nothing to do with the camera chip?

Security for high-definition monitor the effect is really nothing to do with the camera chip?
There are media reports that the security for high-definition monitor the effect of the camera chip has nothing to do, "the article caused the industry a sigh. The article said: "At present the development of IP-definition, or HD evaluate the pros and cons, is to choose what chip, with emphasis on what kind of applications based on off-the-shelf programs can make." This perspective has helped many professionals speechless, security HD monitoring the effect is really no relationship with the camera chip?
The answer is no doubt the negative, it is well known, the core components of the surveillance IP camera is an image sensor and a video processing chip, to achieve good image quality, in addition to the distal end lens camera processing, the image processing section, the sensor portion of the light is also not be ignored. ring. Chip as the core processor, the effect of high-definition monitor is plays an important role.

ISP join hands DSP chip to enhance the monitoring quality
The ISP (imagesignalprocessor, image signal processor) is an important device in the CMOS and CCD camera, the main function is for processing the charge information of the CCD (or CMOS) accumulation in the imaging process, including the linear correction, noise removal, removal of dead pixels , the interpolation, white balance, auto exposure control, and so on.
DSP (digitalsingnalprocessor) is a unique microprocessor based digital signal processing large amounts of information devices. Directly from the image sensor is bad, regardless of color or detail of the actual image, can only see the broad contours of the objects in the image. Using a dedicated DSP chip as the ISP can greatly improve the camera's video processing and operational performance. ISP processing, including interpolation, de-noising, go to the dead pixel edge enhancement, color correction, white balance and other operations, you can make the images more delicate, closer to the image of the real world.
Camera with low-light, wide dynamic through the fog often using a dedicated DSP chip for processing. Thus what kind of image sensor processing DSP chip impact effect, thereby affecting the results of monitoring. Thus, monitoring the effect of the camera chip is closely related to the not unrelated.
HD IP Camera inside the compression chip and CPU processing power are higher, and the processing power of the chip is mainly reflected in the resolution, low bandwidth, multi-stream applications. HD IP Camera vast majority of IPC, IPC video codec and compression inevitable loss, there are also different in different video codec and compression processing chip compression ratio and image quality. Processing chip compression ratio is greatly affected high-definition monitor quality better or worse.

Chip upgrade only to improve the monitoring results
The chip has been restricting the development of China's electronic industry, for many years has been the people's heart disease, people have been eager to get rid of "foreign chip" to contain. Terms of security, the chip has been a key factor in restricting the definition of monitoring, in recent years, in order to enhance the image effect, some companies actively developing chips to enhance the functionality. Sony, for example in order to enhance the CMOS chip image effects, including sensitivity and wide dynamic, in particular, has developed a new feature - View-DR. This function contains three advanced technologies: multiple exposures wide dynamic technology, enhanced visibility (VE) technology developed by the professional security monitoring high sensitivity ExmorCMOS.
Generally wide dynamic open sensitivity will be reduced, but by opening the View-DR function, not only the wide dynamic range over 120dB, and compared to traditional wide dynamic sensitivity 2-fold increase, while the contrast increased four times, the image effect greatly enhanced and improved in low light and strong chiaroscuro. Noise control in high-definition surveillance IP Camera, Sony also has a unique Super Dynamic Noise Reduction the technology (XDNR), while noise reduction can be guaranteed of moving objects sharp edges trailing.
With the development of millions of HD IP Camera chip, the degree of integration also getting higher and higher, along with peripheral devices will be less and less, will be getting lower and lower power consumption. In order to achieve the system with digital high-definition IP camera have both suitable for image sensors for security applications, also supported by the decoder chip technology for docking with the back-end, back-end decoder chip performance has yet to be a bigger breakthrough. Therefore, innovation and upgrade of the chip to become the focus of the industry.

Security chip high-definition intelligent direction
Prospects for the development of China's chip industry, the State Council released late last year "speed up the cultivation and development of emerging industries of strategic decision" clearly the chip industry as the core of basic industry.
