First, easy to use, easy to operate
Network DVRs have very simple and convenient use and operation features, so you don't have to worry about the operation and use of networked monitoring.
Second, flexible and reliable storage
Network DVRs also have highly integrated and convenient video storage features, which can be centrally stored through local hard drives, and can meet massive storage needs through external storage devices. The front end in the DVR system is an analog device, which cannot be used for front-end storage.
Third, flexible deployment
Thanks to the fully networked architecture, the monitoring point device and the network DVR can be interconnected via any IP network. Therefore, there is no geographical restriction in the network DVR system.
Fourth, full management, centralized maintenance
The network hard disk recorder adopts full network management, which can realize the whole process monitoring and centralized management of transmission lines, transmission networks and all IP front ends.

Network DVR Advantages
- convenient wiring, low cost
The network DVR only needs one network cable to complete the wiring and installation, and realize the access of all monitoring signals of all monitoring points. The DVR needs to provide multiple cables for video, audio, control and alarm for each monitoring point. . Therefore, the network hard disk recorder is very simple and convenient in the center wiring and maintenance.
2. secure encryption
In the network DVR system, the IP front end can perform AES encryption on the code stream when uploading the code stream, and cannot be decoded even if it is intercepted on the network. In addition, through the carrier-class user authorization and authentication mechanism, the network DVR can effectively prevent illegal users from logging into the system.
3. the installation is simple
DVR installation settings are simple and do not require complicated configuration. The central network DVR device and the remote monitoring point IP front-end camera only need to plug in the Internet cable and turn on the power. All the processes can be completed automatically, including automatically searching all front-end camera devices, automatically assigning IP addresses to the front-end monitoring devices, and utilizing the network. The display device connected to the DVR automatically displays all the monitoring point images in multiple screens.
Network DVR Advantages.
Network DVR use
The video recorder is an indispensable device in the closed-circuit television monitoring system. It can record the scene of the surveillance scene in real time and in real time, and can conveniently search and verify after the event, providing important clues and evidence for the case detection. With the development of digital compression technology and large-scale integrated circuit technology, digital hard disk recorders (DVRs) have developed rapidly in the TV monitoring industry. Only domestic manufacturers that can develop or produce DVRs by themselves have far exceeded 100 companies. And, the structure and implementation of each DVR are not the same.
The monitoring points of the network DVR system are all IP front-end cameras, so only one network cable can be used to complete the wiring, and the network access to the central network DVR through the IP network; and the front end of the DVR system is an analog device, each monitoring The front-end to the center requires multiple signal cables such as video, audio, control, and alarm. Therefore, the front-end cabling of the network DVR system is very simple, and the wiring cost is very low, and the existing network can be used.
