The opportunities that HD surveillance brings to NVR
This article refers to the address: http://
In the video surveillance industry, in the past two years, in addition to the network represented by NVR, the other should be high definition. In fact, for video surveillance, image sharpness is indeed the most critical feature. Because the clearer the image, the more obvious the detail, the better the viewing experience, and the higher the accuracy of application services such as smart. It can be seen that the introduction of high-definition performance will bring a series of all-round and dramatic improvements to the practical application of the video surveillance service, and the importance of HD to video surveillance is self-evident.
Although NVR has many innovative advantages, the real popularity also needs a core competitiveness to pull, and based on the high-definition technology, high fluency and large-screen, wide-screen display, etc., can greatly improve monitoring. The ease of use of the system and the user's image browsing experience are in line with the NVR's core competencies. At the same time, because the basic premise of high-definition monitoring must be networked, the combination of high-definition and NVR is also natural and natural.
Finally, with the excellent quality of the NVR itself, including the integrated functions that are well-known and recognized, such as access management, video storage and decoding display, I believe that in the era of high-definition surveillance, NVR will face unprecedented opportunities for development. .
Win-win - NVR in turn promotes the popularity of HD surveillance
The dilemma that NVR is facing
However, the NVR's road is not easy. Although its development prospects are good, but to truly replace the DVR and grow into the mainstay of the video surveillance industry, NVR still faces many problems.
First of all, to really replace the DVR, NVR also has an important obstacle to overcome: that is how to turn the abstract concept of networking into the actual needs of users.
The most basic functions of the video surveillance system include real-time browsing of surveillance images, front-end management, recording and storage, etc. Although traditional analog surveillance has been exposed in the current practical applications, it is still possible to implement these simple basic functions. . On the other hand, although NVR has many innovative advantages based on the characteristics of networked deployment, for end users, especially most enterprise/commercial users, they are not willing to change easily without absolute premise. With a new generation of products. That is to say, NVR does not have an important performance with core meaning to promote the popularization of market popularity. Therefore, users are not fully motivated to switch to NVR. They still need a process to accept the new concept of NVR.
NVR is the core to promote HD adoption
As mentioned above, HD must cover all aspects of front-end, central management, video storage, decoding and display, and the most important thing besides the front-end is the central management. In the traditional monitoring system, the central management mainly falls into these categories: NVR, management platform, DVR, PC+ management software, and so on. Among them, DVR and PC+ management software can not achieve high definition due to many key performance obstacles such as image and management. The rest is only the NVR and management platform with full network design. The difference between NVR and management platform is well known. The former belongs to small platform products and adopts integrated design, which is more suitable for the construction of small and medium-sized monitoring systems or the end access of large multi-level systems; while the latter has very good management performance and Powerful resource integration and deployment capabilities, and large scale, the front-end access capability of a single device can reach more than 10,000 channels.
It is usually used in large-scale multi-level cascade monitoring systems such as Safe City and Finance. Correspondingly, its construction cost is also higher than that of NVR.
For high-definition surveillance systems, NVR is a key factor driving its popularity.
First of all, the high-definition network camera cooperates with the high-definition NVR, which has the best cost performance, and can provide image effects unmatched by the conventional standard definition system on the basis of the overall cost difference, thereby removing the obstacles in the cost of high-definition popularization.
Secondly, for a large number of small and medium-sized HD surveillance applications, HD NVR can provide integrated central management applications without the need for a large management platform. In large-scale industrial network monitoring systems such as safe cities and banks, the end uses NVR to aggregate, and the architecture of the upward access platform is also the most reasonable solution. On one hand, the cost of terminal aggregation can be reduced, and on the other hand, the bandwidth pressure of the backbone network can be reduced. .
The flexibility of the NVR and the low-cost features of the integrated design greatly enhance the ease of use and practicality of HD surveillance, which greatly promotes its popularity.
