when choosing NVR is more need to carefully consider

Applications and back-end management is currently NVR basic functionality is the most important feature, so everyone in the choice ofip camera surveillance camera products, for both functional surface to focus on. Currently NVR remote management is mainly based NVR built-in Web server , or to watch , record, playback and other basic operations by opening a remote client software, and remote management equipment and systems , alarm linkage and other operations. The admin can be centrally managed operations on the front and back office applications NVR devices through multiple systems management platform , and background data of remote backup , hierarchical management. The so-called "decentralized control, centralized management ," the monitoring of the truth , I believe that is sufficient to meet the NVR and implementation , so they need special attention in the selection . Hardware and software features In the selection , NVR software and hardware features is a rather important aspect when choosing its software can note whether they have the following characteristics : for example, whether to ip camera system NVR Recorder plug and play and requires no setup, support intelligent retrieval queries , support for 3GPP mobile video surveillance services , security systems ip camera system support for multiple alarm linkage , remote data backup , and so regular automatic . These feature-rich while at the same time , how truly simple, user-friendly, reliable and stable is the most critical. And when it comes to hardware features, such as whether to support PoE power supply , whether as a front-end IP Camera PoE power supply and data transmission directly , is not such as construction becomes more convenient . In addition , the availability of support for VGA, analog video output , with or without supporting data stored outside the expansion and so on. For a long period a large number of points and storage project demands, projects and users when choosing NVR is more need to carefully consider . Then he DVR 's relative shortcomings in what areas? 1 affected network systems and bandwidth , bandwidth-intensive , greater impact on network systems . 2 According to practical experience , affected by the network , the delay is severe, the more high-definition , the greater the bandwidth , the higher the system requirements for the entire network , which is contrary to the independence of the security system . 3 is not independent, fully influenced by the web . Once the network is paralyzed ,surveillance camera security systems then paralysis. Safe City is by building a citywide integrated, multi-functional, comprehensive security control networknetwork camera NVR Recorder , helping police department more efficient and more precise control and combat crime , to ensure harmony and stable development of the urban environment. HD video surveillance as a safe city with an important part of a typical cross-regional , cross-industry , cross- application characteristics . Geographically, the entire system involving the Police Station , county Public Security Bureau ( Bureau ) and the Municipal Public Security Bureau three monitoring center networking. At the industry level , the public security monitoring resources covering many internal and external scenarios , including roads, security mount , an important unit , key parts ,security camera security camera system public places and fire , schools, communities , hotels , banks, factories, mines and other industries . In the application, to complete network camera security camera system surveillance system , video playback , intelligent identification, alarm linkage , and other functions. |
