Banks monitor five important factors that replace NVRs with DVRs

Banking monitoring and networking has been discussed for many years. Various solutions have emerged in the middle. It is only gradually becoming more consistent nowadays. It adopts a networked architecture and uses a monitoring and management platform (CMS) as the core to realize multi-level interconnection and provide alarms. The integration of other security subsystems, such as access control, access control, etc., ultimately achieves the purpose of integrated security that can be both unified and hierarchically autonomous.

However, all discussions have overlooked an important link, or that no unified and thorough solution has been formed in this link. This is the transformation of outlets. We know that the object of bank monitoring and networking is the network. If the problem of the network is not solved, all the networking will be empty talks, and it will leave huge hidden dangers.

At present, most bank monitoring and networking solutions adopt the DVR system in their outlets. The superior branch or branch management platform accesses these DVRs through secondary development. The greatest benefit of doing so is to fully protect existing investments and reduce the cost of networking. However, with the further popularization of network construction, the further expansion of the networking scale, and the further extension of networked services, this method of retaining DVR will bring a series of problems due to the inherent limitations of the DVR's own network performance.

Now, NVR is becoming the best solution to replace the DVR to realize bank outlet monitoring and construction.

What is NVR? NVR is a network video recorder, which can cooperate with network cameras to achieve surveillance video access, browsing, storage, playback and management through IP networks. Since NVR adopts a fully networked solution, it has unmatched innovation advantages in terms of cabling, monitoring point deployment, video transmission, scalability, and manageability, while NVR has inherited DVR integration. Due to the simplicity and convenience of video recording, browsing, and management, the NVR was generally known as the "DVR Terminator" in the industry as soon as it was introduced in 2008.

Five reasons why bank outlets choose NVR Why NVR is the best solution for bank outlet monitoring and reconstruction? The reasons come from many aspects, such as the nature of products and solutions, and the demand for bank networking, as well as the bank's monitoring of future trends.

First of all, the NVR's full network features make NVR has a very obvious advantage in the deployment of network monitoring.

The networked features of the NVR will greatly simplify the internal deployment of network monitoring. With the existing local area network of the network, access from the monitoring point to the monitoring room can be realized without complex video, audio, control, and alarm transmission cables. The network cable solves all signal transmission problems and even requires no wiring when using wireless transmission.

Second, the openness and networking features of the NVR greatly increase the coupling and reliability of the entire networked system.

NVR itself is born for networking, so the performance of NVR up networking is far better than DVR. On the one hand, NVR is not a simple storage device, but an integrated aggregation management platform. It can autonomously manage all subordinate monitoring points and monitoring resources. It can also access the upper management platform, and all subordinate monitoring points and monitoring. Resources can be freely managed and invoked by superior management platforms. On the other hand, NVR's networked open architecture makes it uniquely compatible with other management platforms. Due to the inherent defects of the DVR, the current DVR access schemes for various management platforms have relatively many hidden troubles in terms of coupling degree and reliability.

Third, the popularity of network cameras has made the NVR a natural hub for network monitoring.

With the acceleration of network monitoring and control, the market for network cameras is growing at a double speed, and its applications are becoming more and more widespread and more and more popular. ,

For bank monitoring, deploying network cameras at outlets is an inevitable trend. In the era of analog cameras, centralized access, storage, and local browsing of network monitoring images were completed by DVRs. Then, in the era of network cameras, who will monitor, access, store, browse, and manage the network monitoring images? Must be NVR.

If the network bandwidth is sufficient, then the network points can not be aggregated locally, and all monitoring point network camera videos are directly uploaded to the sub-branch or branch monitoring and management platform, and centralized storage is performed. However, the actual situation is that at present, the bandwidth of most bank branches to sub-branches or branches is very limited, regardless of whether it is a business network or an office network, and leasing of high-bandwidth lines alone will incur relatively high costs, so it must be carried out at the outlets. Convergence. For the network convergence of network cameras, NVR is certainly an inevitable and most cost-effective solution.

Fourth, the trend of high-definition makes network monitoring must use NVR.

With the advent of 720p, 1080p high-definition surveillance products, the era of high-definition surveillance is coming. Banks have always had special requirements for the definition of surveillance images, such as the monitor-based supervision system, so HD surveillance will soon be widely deployed and applied in banks.

The high-definition monitoring must be networked, and the first is to start networking from the front end, that is, high-definition network cameras. Why HD must be networked? To achieve true high definition, the acquisition of video sources must first be HD. Uncompressed high-definition video signals after capture have both analog and digital transmission modes: analog transmission generally uses YPbPr component transmission, and all HD video signals need three coaxial cables to transmit at the same time; digital transmission generally uses DVI, HDMI, or HD-SDI. Transmission, where DVI or HDMI transmission distance is only a few meters, is not suitable for monitoring transmission, and HD-SDI can transmit about 100 meters, but the demand for coaxial cable is very high, the price of the cable is also very expensive. It can be seen that, whether it is analog or digital transmission, the transmission cost of high-definition video signals will be significantly higher than standard definition video signals. In addition, the current high-definition video sensor is mainly CMOS, and the CMOS sensor directly outputs a digital video signal. In the camera, this digital high-definition video signal is directly compressed and encoded by the DSP or ASIC, and then transmitted in a networked manner, which is more economical than the camera directly outputting the high-definition signal. Therefore, the front end of high-definition monitoring must be an HD network camera. In addition, to be truly high-definition, it is necessary to fully support high-definition video in all aspects such as video browsing and storage playback.

That is, banks must deploy high-definition surveillance. Network cameras must use high-definition network cameras. In order to achieve centralized access, management, recording, playback, and browsing of high-definition network cameras, NVRs must also be used, as well as high-definition NVRs. In the era of high-definition surveillance, the traditional DVR will no longer exist.

Fifth, the inheritance of DVR features by NVRs will retain the operating habits of network workers.

In addition to the series of innovative advantages brought about by the network, NVR also inherits the simplicity and convenience of the DVR in terms of operation and deployment, enabling the staff of the network to quickly adapt to the new environment and reduce the The cost of training and management.
