HD network NVR will become inevitable

Posted: December 29, 2013 |
Given the domestic market is still analog video surveillance system led,its market demand will remain within a certain period of time is very obvious.Validated in a variety of market sectors, NVR has been fully reflected in its excellent network of video surveillance,which will gradually become the future of video surveillance storage and management market a shining"star".Based on network construction and upgrading quality,NVR products will also be applied to a broader market.For example,the promotion of the business combination NVR network operator has gradually begun to show the advantages,with the network operators have in terms of home users , businesses and other deep resources , network development in these areas has greatly promoted the development of the NVR.In addition to gradually expand the market application surface,NVR system applications from small systems to large-scale system change is also very noteworthy.As can be seen from the traditional analog-digital combination,its system architecture by limiting matrix structure has been very obvious. Modulus combine the traditional way , the expansion has reached a bottleneck,while expanding the scale of manageability requirements are getting higher and higher , and now works as a safe city for the most demanding massive video surveillance storage areas , in the areas of high demand , therefore , is precisely to solve the above problems NVR solution program is currently emerging as the preferred safe project.
Future of video storage will no longer be just a recording and storage of data associated with the video index information , as well as storage and intelligent control relevant additional information , these smart applications will be introduced cloud-based framework for high-definition video surveillance monitoring system . Video surveillance system architecture will provide cloud clustered applications , grid computing and distributed file systems and other features of the device between the networks of different types of storage devices through a collection of software applications to work together , provide external data storage and business function access , in this framework , NVR will further enhance the scope of its application , will play storage node in the cloud architecture , but also will become the compute nodes to achieve more intelligent applications. In this thought cloud storage , video data for each NVR storage on each other back up , not only the greatest degree of assurance of timely and efficient concurrent read and write , but also to ensure the security of stored data and reliable. This efficient and reliable in the future will be to monitor the industry to subvert the traditional business model , by the operator to invest in the construction of the monitoring system, and then provide cloud monitoring service to users, specifically video surveillance cloud services may have the following three modes: platform hire : NVR by remote operators to deploy to build cloud -based NVR surveillance management platform, customers only hire operators monitor cloud service platform and Internet access bandwidth for remote video surveillance broadband network , to achieve real-time image preview, cloud mirror control , historical images inquiries and remote device management functions ; space rental : NVR by remote operators to deploy , building rented storage space operators NVR -based management platform , customers, digital image storage capabilities ; equipment leasing : leasing customers operator's complete set of equipment , such as surveillance cameras , platforms, storage space. Meanwhile , also in conjunction with other professional HD NVR IT storage devices, towards energy saving, low power consumption trends , in addition to energy-saving design of the device itself , it will also increase the MAID storage applications , so that the non -writable disk in a non- working state , to reduce power consumption by optimizing the write mode while recording , decrease or reduce the hardware configuration of the device in the system to save energy . NVR video surveillance as a new industry standard in the near future will gradually replace the monitoring server plus disk array storage architecture , a new generation of video surveillance storage standard solution.
Development and front-end development NVR inseparable IP cameras , IP camera mainly to solve the problem of data acquisition , converted into a compressed bit stream transmitted over the network to the back-end equipment. NVR mainly to solve the transport stream over the store , preview , playback , forward and so on. A few years ago , we may still in the concept stage speculation that the future direction of security.Some manufacturers may only IP cameras, highlighting its high performance, very little research back-end equipment , support for the front-end equipment rarely , can not really form a practical application ; Due to factors such as market demand, many manufacturers are in the increased investment in research and development of terminal equipment , to the present, many manufacturers can provide total solutions based on high-definition , many are also applied to the actual project. But now the problems are: 1, based HD solutions , the cost is still relatively high , can only be applied to the real needs of HD occasions , it can not spread ; only be applied to the project , it is difficult to go channel sales . If you want to spread, in terms of reducing costs , the need to develop and consider ; 2 , due to the standardization of IP camera and NVR Internet is still relatively lagging behind, currently organized in an effort to do the work in this area, such as : onvif, pisa , etc., but the application to practice, there is still a way to go. Development of back-end equipment is now differentiated into two directions: one is the centralized storage direction , major equipment for IPSAN, NAS , etc. ; another is a distributed storage direction , the main equipment for the NVR. Centralized storage is mainly the existence of network bandwidth requirements, capacity requirements for switches to exchange high performance server for central storage requirements, so the overall cost will be very high. Another problem is insecurity centralized storage of data , because it is centrally stored , if the storage server is a problem, the entire data may be lost , the engine room is relatively high ; relative to the centralized storage , distributed storage of data are stored in a single on the stage of NVR, only the center needs to see a preview and playback data, only need to connect the NVR, so the network bandwidth requirements is relatively low , the cost of the entire project will be lower . I believe that from a long-term development trend, distributed than centralized storage advantage.
PC-based NVR NVR currently divided and embedded NVR. PC, PC-based NVR is mainly based, running a NVR management software on it ; embedded NVR is mainly embedded hardware and software platform to achieve NVR. Comparison of two up PC -style NVR difficult to develop a small , easy access to different IP cameras manufacturers, just follow the SDK access to ; rather difficult to develop embedded NVR relatively large , access to different manufacturers need to follow the IP camera protocol access, but embedded NVR low cost, the system is stable . And with the applicable security chip maker launched a series NVR developed chips, such as Hass , TI, Trident and other companies , the development of embedded NVR difficulty is gradually reduced.
