Home monitoring network camera and wireless HD how to solve problems
Plagued by civil security market there are many factors in addition to price factors, the large part of the reason lies in its market applications: high definition and wireless when it can achieve? High-definition monitor environment, whether civilian market popularity of high definition still a debatable topic, But fundamentally speaking, the civilian market is high-definition HD Popular important step in chess; while wireless technology monitoring and network monitoring with zero embodies the advantages of cabling.
HD low bandwidth monitoring - image codec
HD IP Camera surveillance to resolve family way can come in handy. Firstly, or to network monitoring point of view, the codec can do to further upgrade. In the field of video surveillance is more mature as H.264 or MPEG-4 codec, on this basis, a number of security vendors to image compression standard for the development of the source code using H.264High Profile DSP chip.
Home monitoring network camera and wireless HD how to solve problems
H.264High Profile and what advantages does? H.264 codec with the ordinary compared to the upgraded technology can be implemented in 2M ~ 4M network bandwidth conditions, reach 1080p/30 frame imaging results; under normal usage under the terms, H.264HP compression standard can be reduced by 30% of the bandwidth, due to the use of fields and industries distinction is possible to achieve 50% reduction in bandwidth.
H.264HP compression standard would be more suitable wireless network, the wireless network bandwidth is low, so in order to achieve high-definition home monitoring system effects, in theory, is a very viable option. In addition, to the wireless network environment to achieve high-definition monitor, for data loss problems must also be addressed.
5% packet loss had no effect on the video image?
For wireless networks, stability is the test of its network monitoring transmission medium as a major problem. Not to mention video surveillance, is also in the daily internet there may be less than the local wireless network coverage, or signal weak, the data packet loss natural that.
For some companies have introduced anti-loss technique, in fact, not entirely without packet loss, packet loss in the range of 5% does not affect the image quality. In front of high-definition IP Camera, embed the technology can do adaptive packet drop policy, IPC real-time monitoring network status, with HTTP functionality. Simple to understand, like everyone QQ online transfer files, once the network unusual or unexpected termination of resend the file can retain the original schedule, while receiving the full range of past data.
Video surveillance storage
For home monitoring, in addition to solve the above two issues, data transfer and storage is a major problem. If a DVR as a data storage device, the cost will inevitably increase, and will face the wiring process. Small advice, wish to purchase specially adapted for civilian use, home monitoring devices, wireless capabilities in support of the premise, the camera can also be achieved 1080p or 720p standard; in storage, either through software platform storage to your computer, but also can be built SD card, real-time monitoring for, 720p image generates about a month 30G, and now the SD card is also fully meet demand video storage a month.
Anyway, in high-definition video compression codec, not only is the bandwidth is reduced, the same token, the back-end storage devices for pressure is also reduced. High-quality compression reduces data redundancy of storage space, the most valuable information is extracted to achieve intelligent storage is the ideal realm.
In summary, the monitoring of civil or other fields, the high-definition to be coexist and wireless technology, the problem seems to be that we must first solve the problem. Especially in the wireless monitoring technology, the low bandwidth of security companies can not solve the problem, but the only thing to do is how low bandwidth and unstable factors to achieve high image storage and transmission.

Ease insufficient bandwidth HD monitoring solution

Ease insufficient bandwidth HD monitoring solution
HD IP Camera to get large-scale application, in addition to passive network operators expect to make some adjustments, but we need to take some proactive alternatives to alleviate HD IP Camera network bandwidth is not enough of contradictions.
The use of advanced video compression standard
Active use of advanced video compression standard, to ensure that with the least amount of data to achieve the best image quality, but by the image coding technology and intelligent technologies, the use of local coding method that can considerably reduce the required HD image transmission network bandwidth. Currently, there are three mainstream compression format, namely, JPEG, MPEG-4, H.264. JPEG is a single-frame image compression, a single picture works best, but a large amount of network bandwidth resources; MPEG-4 and H.264 is a continuum between the frames compressed. Wherein the most popular compression formats H.264 highest compression efficiency, H.264 compressed video data through the network during the transmission bandwidth required less.
Provide dual-stream support
In the realization of high-definition local recording while using dual-stream technology can both reduce the long-distance transmission bandwidth usage and ensure that local better image quality. HD IP Camera remote monitoring environment that provides all the way to high-bit-rate HD stream for local storage, such 720P/1080P coding, all the way to low bit rate streams for network transmission, such as QCIF / CIF encoding, taking into account local storage and remote network. Flexibility to choose according to network bandwidth stream format, to local HD storage, while the back-end low stream network transmission. Users can obtain in the case of limited network resources, to ensure stable operation of the transmission system.
Smart technology to improve added value
Smart technology can improve monitoring efficiency, it can bring value to more than that, through the pre-coding and intelligent analysis, embedded intelligent analysis module definition network camera can grab from the source of valuable information and then spread to the background, can reduce the transmission pressure, truly effective transmission. HD IP Camera capture images on their own to analyze and judge, and the alarm signal is transmitted to the back-end system, which is different from the smart technology to transfer images to the back-end system and then analyzed by software alarm mode. Conventional method needs to occupy too much bandwidth and storage space, and as the image signal during transmission loss exists, prone to false alarms. The HD camcorder since all signal processing inside the camera in the preceding paragraph, the signal is the most complete, so greatly enhance the accuracy of the alarm, while reducing bandwidth.
Complete front-end caching technology
Front-end caching technology designed to ensure the equipment images are not lost. HD camcorder itself data storage capacity is limited, depending on the communication transmission and back-end storage devices. We can front-end caching mechanisms designed to prevent loss of data communications failure. For example, in high-definition network camera system design, optional on-board memory or other storage device, and supports offline. In the case of abnormal network interruption, data can be temporarily stored locally, such as the network returned to normal after the server returns. But also through network technology, network front-end cache temporarily interrupted until the network is restored automatically upload recorded data, thereby ensuring the integrity of the video.
Establish and adhere to industry standards
Monitoring market is necessary to unite the manufacturers to develop some of the prevailing norms, seeking common ground while reserving differences. Currently Onvif, PSIA standardization organizations such as the emergence of people see video products and systems standardization of hope. Video Surveillance "plug and play" era believed to have been far away.
Summary: surveillance network camera represents the future of surveillance cameras. At this stage, our optical transmission system, represented by a high-speed network transmission technology applications are gaining popularity across large geographic range ultra high-speed backbone network and high-speed local area network has become the norm facilities, a large stream through a network of high-definition images real-time transmission has become possible, but also constantly tariff reduction. These are high-definition monitor to open a broad space for development.

Network camera wireless transmission technology

Network camera wireless transmission technology
HD monitor as a front-end covers, transmission, management center and back-end aspects of systems engineering, control systems due to the transmission distance, flexibility, deployment cost constraints bound to network.HD IP Camera as a high-definition monitor front-end equipment, will also move towards network.
Network camera wireless transmission technology
HD network camera provides a clear visual experience to the people, but also for network bandwidth has put forward higher requirements. Real-time video to 720P for example, using the standard H.264 Main Profile compression algorithm requires at least 2Mbps HD Network Camera to get "high definition" of the visual effects, and full 1080P real time video you need 4Mbsp more. Ordinary ADSL upstream bandwidth already unable to meet the needs of high-definition video. With 3G, Wi-Fi, private network and other wireless and wireline broadband technology matures and applications, remote data transfer large flow more easily, which also swept away theHD IP Camera applications in a wide range of transmission barriers.
At present, the safe city, the financial network monitoring and other projects usually self-built fiber network or local area networks 1000M bandwidth networks. This gigabit bandwidth resources, installing 100 road in front 1080P FullHD IP Camera real time (even if 4Mbps per channel footprint calculation), occupy less than 50% of the total bandwidth resources; 720P transmission if it is used, the bandwidth can be reduced by half. This can effectively support the practical application of high-definition network camera.
Wireless transmission, 3G network speeds up mobile Internet speed, so that video telephony, mobile games and other applications in full swing. But in security video surveillance industry, still no substantive application. The reason, first 3G network construction is lagging behind; Second 3G tariffs still too high. The face of high bandwidth requirements for video surveillance, 3G is not make it. To realize high-definition wireless video surveillance, but also need to wait until the 4G promotion. Currently, TD-LTE appears, for the 4G era we opened the door to high-definition video surveillance.
TD-LTE TD-SCDMA is the IMT-Advanced (4G standard) direction and evolution based on both inherited and developed China's independent intellectual property rights TD-SCDMA technology, also received broad international support. The TR25.913 defined by 3GPP, LTE peak rates of demanding, uplink 50Mbps, down 100Mbps. From the perspective of spectrum efficiency, either upward or downward spectral efficiency are our current network of 3-4 times. LTE technology development has attracted the participation of different institutional norms, including UMTS (ie 3GSM), there CDMA2000 camp participation so that LTE 4G wireless networks gradually become a possibility.
In the Shanghai World Expo, China Mobile to build TD-LTE demonstration network's coverage Expo 5.28 square kilometers, to build a TD-LTE outdoor station 17, the realization of the nine venues indoor coverage, including seven venues in Pudong and Puxi 2 venues. TD-LTE demonstration network based on the movement of high-definition conferencing, mobile high-definition video surveillance, mobile high-definition video on demand biography, business presentations and other portable VXIS are open to the public, and have achieved good results.

Redefining Megapixel Network Camera

Redefining Megapixel Network Camera
Megapixel IP Camera is a network monitoring system main equipment, and some well-known manufacturers to give it a new definition for intelligent monitoring brings a useful inspiration. We usually think of one million high-definition network camera is a device generating image information, IPC is to produce a digital image information flow devices. IPC The new definition is: generating image information and value-added information devices. Added information include: information on image quality, image defocus inadequate illumination, image (lens) caused by pollution of image quality deterioration; image detection information, image content analysis functions, the image is not found in the normal case, with the relevant ( alarm) information; equipment status information, IPC status monitoring and network environment, the fault self-diagnosis can be adaptive to the environment, and issues relevant information. With these features, IPC has a smart, intelligent monitoring systems become the basic (minimal) unit.
More innovative is, IPC added when information can be passed to the adjacent IPC (interconnection, transmission probe information, sensor networks): to achieve between IPC, IPC and monitoring interconnection between the target and the real perception and interaction, This is the sensor network (IOT basic unit) concept. Such as the monitoring of multiple IPC target tracking; comprehensive IPC IPC discovered targets fixed automatic tracking. Such a system is the real things. So: video surveillance intelligence is the key technology to build things; IPC constitutes an important element of things.
The framework for determining the image of intelligent system architecture also has a good inspiration, indicating that the image is the best structure of intelligent systems: Distributed Enhanced Processing Architecture (DEPA). Detection function is performed by both the front-end video equipment to complete, and comprehensive analysis of the image information, the information associated with the system background. It is consistent with the characteristics of the image signal in the image before compression, and space image data stream to keep the image in time and space correspondence between the individual identification, content analysis of the best mode, the compressed data stream, without it kinds of correspondence, and with the injury, the above process is very difficult. So IPC image signal is generated while producing value-added information technology is the most reasonable route. Again, the front IPC sensor network monitoring system is also designed to monitor the area the best explanation. Monitoring system can not a point, a point of isolation to design IP Camera, to establish the concept of monitoring area, the surveillance zone Megapixel network camera configuration (number, selection, function), monitoring results and objectives of the overall planning.
Monitoring area will be designed to enhance the system capacity and efficiency of real-time monitoring; improve the system quickly capture events for complete information. Businesses in the real summary of the "eight wars Law", usually with manual control or programming designed and implemented. The former low efficiency, which is the lack of interaction with the control objectives. IPC may constitute an intelligent sensor network monitoring area, the monitoring system through the analysis of the target image, self-realization of the above tactics.

The use of HD IP Camera trick

The use of HD IP Camera trick
With the rapid development of science and technology, HD IP Camera has become increasingly popular, functional and image clarity is also clearer. As the top three security brands in North America, Chile Metroplex, the development of HD IP Camera is its extremely important directions. Following on from the technical staff for HD IP Camera how to use are introduced.
HD network camera installation and commissioning
In the daily video security projects, high-definition cameras and surveillance cameras ordinary household installation and commissioning is basically the same, but must pay attention to good lens optional, because the poor quality of the lens, or bad option, will largely affect the clarity of the screen, such as infrared night vision camera system best selection of infrared camera, and 1/3 inch CCD generally equipped with 1/3 inch lens, 1/2 inch CCD generally equipped with a 1/2 inch lens, installation and commissioning, commissioning must focus the lens a good tune, especially the back focal plane of the camera to be aligned, often focusing lens can cause image blur unclear, reach high-definition requirements. Another shield the camera can not be ignored, gun-type glass can not shield the distal end of the normal glass, but must use the good optical glass, the glass of the image generally has a very powerful weakened resolving effect, the choice Ball casing should note that the spherical curvature to smooth the transition, it is best not to the camera lens at the upper edge of the shell, where the refractive power of light is large, even seriously affect the image sharpness. It is important that no matter what kind of cover, the best light as low as possible within the enclosure, the lens to cover the distance as short as possible, so make front of the camera to minimize light pollution, help to improve the image clarity.
In addition to HD IP Camera attached to the tip and the selection must be noted, also must have a transmission system, the intermediate system and terminal display system can be achieved with the use of high-resolution actual results.
On the transmission system, the transmission of video images will generally choose coaxial cable, twisted pair, UTP cable (ie, network transmission), radio transmission, cable transmission, etc., regardless of the manner in which transfer, you must transfer the image from the front to-back in the entire system bandwidth of each looping> 6M, so as to ensure high-resolution image to achieve the requirements and comply with anti-technology engineering and testing is requested. Under normal circumstances coaxial cable over 150 meters or 200 meters, the image quality will be significantly decreased, which is due to the characteristics of the coaxial cable itself, it must take all measures to ensure that their end bandwidth is not less than 6M, if necessary, to give extra Video compensation amplifier to solve general video amplifier plays a minor role. The indicators should ensure that the compensation amount of high-frequency compensation, frequency characteristics, SNR, common mode rejection ratio, differential phase distortion, crosstalk delay, width chroma gain and so reached the relevant cable loss or attenuation caused defects are compensated into the system in order to ensure a high-definition image.
Currently, as copper prices are rising, the video image using fiber optic cable transmission costs continue to decline in the longer transmission distances or multiple images, the use of optical fiber transmission may well staffed programs are widely used. Since cable bandwidth, attenuation, high noise immunity, small size, strong security features, image transmission can be well assured of the indicators. When using other ways to transfer images, you must also ensure that the channel bandwidth. High-resolution images also must rely on good terminal display device to show in front of people's vision, it is the best choice for progressive scan monitor. Because in actual use interlaced monitor image flicker serious, it could produce visual fatigue. If the low-resolution monitor overall clarity is also not up to the requirements. Because the monitor's resolution by the monitor, the video channel bandwidth and CRT dot pitch, will be at the decision. According to statistics, the channel bandwidth and clarity between the theoretical upper limit for the 1M/80 line translated around, if more considered high definition
In line with the use of high-definition Network Camera, intermediate processing equipment, including matrix, DVR, video server, video encoder, etc. are all kinds must meet the requirements of bandwidth and image compression, to make high-definition camera to its full intrinsic effect. Rely on the use of high-definition Network Camera while ignoring other ancillary equipment used is not up to the real purpose.
Therefore, in complete security surveillance system, HD IP Camera plays a very important role, so buy HD IP Camera must be comprehensive consideration before use must consult relevant experts, so as to the correct use of monitoring systems .

Several commonly used IP Camera networking

Several commonly used IP Camera networking
Although the Network Camera is easy to install, but due to complex network environment, or will encounter a lot of problems, especially with regard to network for remote monitoring, because of its convenient features welcomed by consumers, has gradually replaced traditional analog surveillance cameras trend. So today we say IP Camera for networking problems.
         1 About Auto Dial
Many of my friends are taking the Network Camera comes with auto-dial feature, but due to fault-tolerant Network Camera dial relatively poor conditions often occur dropped seriously affect the stability of the control system, and in this we recommend you, if the conditions permit, preferably through good stability router to dial.
        (2) on a dynamic IP
For some reason, in general we are using dynamic IP, which gives us a remote login IP Camera cause some problems, the following is a common solution.
(1) through DNS.
Domain analysis of two kinds: own and third-party DNS domain name resolution.
Manufacturers need to set up its own DNS resolution server or set up their own, the advantage is resolved relatively stable, of course, the cost is relatively high, ordinary users can not afford.
DNS through a third party, is more famous peanut shell, the advantage of mature technology, relatively low cost disadvantage if the network link is sometimes not very stable.
(2) Buy a fixed IP
While the cost of this approach is more expensive, but the stability is good, the transmission speed.
(3). Himself set up the server.
Not recommended for normal users adopt this method.
        3 With regard to residential broadband, MAN
Former home monitoring most troublesome is met residential broadband, LAN type of problems, because the average person is not very clear on the network settings, residential broadband ports and the like can not be mapped, so it became home monitoring of an obstacle.

Teach you how to care for IP Camera

Teach you how to care for IP Camera
IP Camera in our lives are more and more widely applied, because it can be a good thing to record the development process, usually used to control a region or something dynamic. Life, HD IP Camera is everywhere, such as elevators, shopping malls, roads, banks, etc., many places will see its shadow, it's like time recorder around us.
No matter what items will have some useful life, everything has its own shelf life, for HD IP Camera is no exception, it also has its own life, but as long as it with good storage, can be a good increase its service life, the following share with everyone the maintenance of IP Camera.
1 Before using the network camera, they must be careful not to over-collision, not to fall, or the lens is easy to go wrong.
(2) after a period of use network camera, the lens surface will be stained with a lot of dust, affect the imaging results, so when in use must pay attention to intermittent use alcohol to wipe the lens, do not rub random, but alcohol also If industrial alcohol.
3 To pay attention to the packaging of the camera, even when in use must also be careful not to let it be wet with water, or easy to malfunction.
We can find everywhere around the size of the network camera's figure, which regulate some of our habits, in social development plays an important role.

What are the advantages and disadvantages million HD IP Camera

What are the advantages and disadvantages million HD IP Camera
Megapixel network cameras monitoring almost become a mainstream product, not knowing that one million HD IP Camera has its unavoidable shortcomings.
1, the first is occupied by storage capacity. If you press 2M stream computing, each image will occupy 0.9G space per hour, the same ratio D1 network camera than doubled. Demanding that the computer again, because of the high definition image decoding to consume more CPU resources, decoding an HD network camera, roughly equivalent to four standard definition decoding network cameras.
2, some of the high-definition network surveillance cameras SD illuminance is less than good. This mainly refers to the majority of CMOS HD products, but this problem has been dramatically improving, and before long, this problem does not exist. The CCD HD network camera illumination problem does not exist, but the cost is too high, so the current is still the mainstream of CMOS products.
3, more bandwidth. 1080P HD network camera by calculation, the amount of information that is 5 times D1 cameras by optimizing encoding compression, bandwidth of about 2M, D1 network camera than twice as much. If used within the network is also a big problem, but to long-distance transmission, you have to use the line, ADSL is not enough.
Even HD IP Camera have these disadvantages, but we still have a lot of ways to circumvent, some issues such as bandwidth, even if the current is not a good solution, but development point of view, it will certainly be solved.
Let us say that it is the application of advantage.
Network Camera not only computer-based local area network for regional monitoring, such as monitoring residential, office buildings, banks, shopping malls and other traditional monitors; but also through the INTERNET across the region for the new remote monitoring and online display, remote child and elderly care , unattended monitoring communications room, tourist attractions online telecast, products, online exhibitions.

Buy HD IP Camera need to pay attention to several aspects

Buy HD IP Camera need to pay attention to several aspects
Now people in the choice of surveillance cameras, HD Network Camera is the first one first thing to consider, too many brands of HD IP Camera, you often do not know how to choose, well, it would only buy u guys elaborate definition surveillance cameras several key factors, allowing users to judge it.
Monitoring Performance
When the purchase of surveillance cameras, must be clear what kind of monitoring required to achieve results. If you need to see the facial features, and license plate number, counter, etc., then select HD IP Camera is wrong. But the demands of everyone is not so high, it is not necessary to choose a HD Network Camera, choose a standard definition can, after all, still more expensive HD IP Camera.
Definition and function
In determining good to buy high-definition surveillance cameras, you need to look at the camera's functionality. First look at the camera screen clarity, here to note that both static images and dynamic images need to watch to see Gao Bugao color reproduction, the picture is clean, natural and realistic. In addition to these, you also need you to look at this network camera products have the following features: wide dynamic, automatic white balance, image sharpness adjustment, super digital noise reduction, intelligent digital automatic metering compensation. Check the wide dynamic transition is to see whether natural clear light. Illumination is in a dark environment to see more of an index object, for night monitoring, the smaller the better.
When looking good at several functional parameters, that is not their own to HD IP Camera should be very clear. Finally some of the details of that. For example, when the camera operator simply do? Menu is rich? And this camera it has several environmental models? Data Interface There are several? Lens what? Software system how? Service this brand how? Ah, and so there is no technical support .

Advantages of using IP Camera monitoring

Advantages of using IP Camera monitoring
IP Camera are now in many industries have been widely used, changed in the past simply to monitor activities on human behavior, it can be said that the birth of a new era of development must, its body has many advantages, the following come and we explore HD IP Camera is widely used, its main advantage is.
1 IP Camera are electronic products, love that is more delicate, but the network camera is rarely demands on the environment, it was adapted to any environment, less demanding on the environment because of his comparison, we will generally quick to some the human eye is very rare, or a lot of places to see it.
2 It's like a pair of human eyes behind when people happen after some unpleasant things, it can always play fair and equitable results, can be very effective to restore the truth.
3 Its resolution is particularly high, even under harsh environment then it can also play a role in a good, clear image.
4 also has a network of intelligent front-end focus on the effect, in the present life, it has played a good role in monitoring, security personnel are now sitting in control room directly observe the development of things.
5 cost is relatively low, like in the past a lot of eh need a lot of manpower to come forward to deal with, but now with it then you can significantly reduce labor costs, and with the development of science and technology, and its production cost is gradually reduced.

IP Camera to scale applications

IP Camera to scale applications
Video surveillance systems for the network core equipment, application and popularization of IP Camera network video surveillance represent the extent and stage of development. Needless to say, the network camera is gradually adapting to the diverse needs of current and future, will become the mainstream of video surveillance products. But for most users, network camera, its performance, stability and fusion, but also a clear and thorough understanding enough, the lack of in-depth, systematic analysis and research. Therefore, decisions, often have more concerns and doubts that dare to try, which is also largely affected the HD IP Camera and network monitoring systems and a wide range of universal application.
According to Granville Xindakang application in the industry, combined with the actual business promotion network camera products encountered during the many feedback, Network Camera can basically scale promotion of the application of customary factors summarized as the core technology, network transmission, procurement costs, application value, resource integration and other six areas.
First, the user from the concept has formed a kind of inertia, that the current market liquidity large, wide application, long survival time video surveillance products is the best choice, so market share is still dominant DVR + analog cameras became the most preferred customer or contractor. This network camera view of this new generation of products, it will be in the invisible into a misunderstanding, the user will think of new technologies, new products will certainly be premature, prone to problems, such as the imposition of performance instability, system installation complexity by the external environment impact, operating difficult to master, and so shortcomings. Visible changing concepts is constraining the development of network video surveillance fundamental factor, only look at new things change this concept in order to make faster and more comprehensive IP Camera are understood and recognized, and play its due advantage.
Although domestic network video surveillance products can be said to contending, but most security vendors do not own the core technology, especially video and audio development, monitoring and management software development and image processing technology, still in the "ism" and "Zanji" A low level of technology. Such a unified standard and not really close to the domestic market demand, technological atmosphere, give security contractors and integrators to increase quite a lot of unnecessary trouble, often for a network video surveillance system solution, to find a variety of monitoring equipment manufacturers, patchwork, but also integrated design solutions, not only a waste of time and energy, but also increases the cost of procurement of technology and products, which can not really be achieved with international brands confrontation and competition, not to mention a station style system of solutions and services.
Network video monitoring system, by definition is universal network video surveillance system deployment and application implementation. Network environment is the foundation of the network video monitoring system of the carrier, a good network environment in order to smooth network video and real-time provides a good protection. While the domestic network status is very people can not let go, whether it is green, ADSL, CDMA, 3G, etc., have very limited bandwidth, and the actual and theoretical values ​​vary greatly, compared with developed countries, China's so-called broadband, the vast Most also can only be defined as narrowband, digital video transmission will be faced with the dilemma of narrow roads and vehicles, resulting in the screen quality, screen interruption, delay too long, and so on.
Users for Network Camera, network video surveillance system construction costs have deep misconception that high price of IP Camera and network video surveillance system, compared with, DVR systems, the cost is much lower. However, as users demand gradually to the network, high-definition, intelligent, centralized management, systems integration direction, DVR systems are essentially already appeared to be inadequate. In fact, from another angle, HD IP Camera function, has both analog cameras, DVR functions encoded with analog camera in price has not comparable. If network video surveillance system construction costs, including hardware costs, implementation costs for analysis and accounting, to meet the needs of high-end applications in the premise, network video surveillance system construction cost is usually fairly basic system with DVR. But the reality point of view, many users already have the DVR system in use, if you want to carry out a system-wide network transformation, a lot of monitoring equipment will be dropped, does cause a huge waste of the original investment, it is difficult for users to accept and therefore, although the obvious advantages of IP Camera, but in the actual product procurement and system construction, it is also necessary to protect the user as much as possible the original investment. The good news is that Ray has launched such as the security hybrid DVR, multi-system management platform and other products, you can not change the existing system architecture and products under the premise, network transformation, the maximum guarantee of the user's pre- investment, to meet the economic, compatibility and advanced integrated requirements.
As the trend of more and more IP surveillance vendors, channels, accepted by users, network camera surveillance products as a new trend, so that more manufacturers to join in the IP market. However, the complicated network camera technology also allows the industry chain cooperation between the manufacturers more closely. Lens, sensors, compression processing chip, three are indispensable, must through close cooperation, to improve compatibility with each other, understand each other characteristics and limitations in order to get a better image quality. The video compression part, dependent on the chip makers and camera manufacturers in close collaboration with a software program to adjust and continually optimized in the details necessary for both sides closer cooperation. And network monitoring system openness and integration features, also produced a more unified management and linkage alarm needs, its core is the management platform and multi-vendor network camera product compatibility integration, which requires IP Camera manufacturers and platform vendors joined forces, together with the completion of the construction project as a whole network video surveillance.
Closed with analog video surveillance systems, digital video surveillance system products and product systems to achieve compatibility between It has become severe in practical engineering problems. Different technical standards, will cause the device to search for real-time video, audio, metadata and control information on the interaction difficulties, so the discussion on increasing the standard, the standard setter, can guide even control the entire industry, This is the most lucrative part, for which, ONVIF, PSIA two standards organizations are competing with each other, who the winner is still unknown. To address this situation, such as foreign ACTI, domestic satellite network Ruijie other monitoring vendors, increasing R & D investment, to take all the support both standards strategy to meet the status quo in order to dispel the concerns of users and eliminate hidden dangers affecting the normal operation of the system .
Domestic network video surveillance market is still no scale, facing a huge market, all kinds of camera products allow buyers dazzling, most users still on the sidelines. In some already built or under construction network monitoring system, the actual use of the process, there are still many technical and non-technical factors obstacle, so in the promotion and application of HD IP Camera is facing many challenges and obstacles.
However, we are also pleased to see that Shenzhen Wei Technology Co., Ltd., as the dot-com pioneer determined to do, doing painstaking research and development, launched a series of high-definition, high-noise, high intelligence, low stream, illumination of the high cost of network imaging products, and has been successfully used in many high-end industries and fields, the popularity of the network camera off to a good start. Trends represent things inevitable evolution, I believe that the major manufacturers and industry support and joint efforts, the optimization of Network Camera will be more close to the user's needs and practical environment, and the popularity of IP Camera will be more accelerated progress pace.
