NVR is not a replacement for the DVR

NVR is not a replacement for the DVR
DVR appeared on the stage of the digital video surveillance technology is a mature product after years of development . DVR in video codec technology, network transmission technology , embedded technology, storage management technology and personalized application technology has a profound accumulation. Meanwhile DVR rich experience and specific applications , but also created many kinds of product form .
NVR appeared in the digital stage , access to the network development stage . Many major technology directly from the DVR, such as memory management , on-demand, network transmission , embedded technologies. Inheritance of mature technologies , making NVR can quickly reach the practical level, but on a mature technology with a heritage not just talk about it can be done , it needs to produce a higher level of technology companies and deep technology , the accumulation of experience . In addition , NVR DVR on the basis of inheritance as well as the development of high-definition is a typical example.
With the technology development phase of change, there are many views on the development stage of the network NVR deemed born in stage DVR digital alternative , of course , and the "replacement DVR" as NVR existence of " mission" and "target" . But this view ignores the fact that , intentionally or unintentionally , that is - DVR and NVR products are suitable for different needs , their goals are different designs , different problems , not the same trajectory , so although developed in a different era , but does not affect both meet the needs of multi-level marketing . If the NVR locate alternative location on the DVR , then I am afraid that ignores the true value of NVR 's lies.
NVR fog
NVR ( Network Video Recorder ) , is on the market in recent years gradually rise of a product form . Its main function is to record online video streaming , video -on-demand and provide other functions. If we trace the origin of the concept of NVR , you will find that it does not appear much later time than the DVR. But until recently NVR frequently enter our field of vision , the reason is due to a network camera NVR IPC backend supporting products, network camera in recent years with the rise of the IP Camera , its value gradually concern for people .
For network camera industry prospects IPC has almost reached a consensus , however, understanding the NVR as well as its future development ideas , the industry rarely have the same voice. For now seen to analyze the situation , one is involved in a number of vendors and their market position, technology and technical background is different. On the other hand is the way to achieve a variety of NVR , the software in the form of pure NVR software, pure hardware in the form of embedded NVR, as well as to show people the face of the disk array storage type NVR, the road to a few small -scale stand-alone NVR to the platform level NVR-Server ...... difficult to use a uniform standard or form to summarize. Finally, from motives of view, some manufacturers in accordance with the law of the development of industry and technology, the NVR system in their products as necessary to supplement and improve long-term planning , but some vendors will as a kind of short-term profit growth , acute for this piece in the newly opened "battlefield" on " to regain lost ground ."
All this created a flourishing NVR market today , contending situation. This situation vaguely shadow then just started some DVR . But experience tells us that - any kind of product , regardless of its position on how , what was given advanced concepts , its core values ​​should be based on user demand as the center, otherwise it is difficult to escape the fate of being eliminated . This article from the perspective of a brief analysis of the needs of the real value lies NVR products , for information .
