Industry Analysis: NVR will eventually become a replacement for DVR

Industry analysis: NVR will eventually become the replacement of DVR With the rapid development of the Internet era, video surveillance industry has gradually entered the all-digital, network era. In the process of video surveillance being fully digital and networked, DVR has played an extremely important role. It can be said that DVR has created a digital surveillance era.

However, with the increasingly fierce competition in the video surveillance market, homogeneity of products has become more and more serious. People are increasingly demanding the networked monitoring. Not only do they have to implement monitoring locally, but they also want to be able to monitor remotely or even wirelessly, and these can only be networked to meet the needs of users. Digitization and networking of video surveillance are the trend of the times. Some major manufacturers such as Kodak and Ruihu Technology have all launched higher performance, more humanized new products, NVR, “replacement of DVR”.

In fact, NVR can also be said to be a networked upgrade of DVR. NVR is a digital, networked monitoring system. With networked front-ends, it can build a complete set of network video surveillance systems. NVR also has multiple advantages over DVR.

First, when traditional DVRs are deployed, they cannot be remotely deployed due to factors such as transmission distance and analog signals. The NVRs can be deployed arbitrarily regardless of geographical restrictions. Secondly, we all know that DVR's recording and storage functions are very powerful, but it cannot always achieve front-end storage; NVR products and systems can support central storage, front-end storage, and client-side storage, and can realize mutual backup between the center and the front-end. In terms of storage capacity, NVR also has a large-capacity hard disk that can satisfy mass storage. In addition, the management module, because the center to the front end of the DVR is an analog transmission, it cannot realize the real-time monitoring and centralized management of the transmission line and the front-end equipment; and the NVR can not only realize the monitoring and management of transmission lines and transmission networks, but also Can realize the whole process monitoring and centralized management of all IP front end.

In the security industry, network monitoring and digitization of video surveillance have become an unavoidable trend. It is a trend that the establishment and improvement of security infrastructure is of utmost importance. The development of NVR has brought greater hope to the security industry. With the continuous development of many technologies, it will drive the further development of NVR, and will become the market leader and even the replacement of DVR.
