A, flexible deployment
Huicong security network due to the use of network architecture, between the monitoring equipment with NVR can be any IP network through the internet. Therefore, in the NVR system, an arbitrary position monitoring point can be located in the network, and achieve rapid deployment, not subject to geographical restrictions

While the DVR system, between the monitoring point and the center of DVR by means of simulation interconnection, affected by the transmission distance and the analog signal loss, monitoring point position has great limitations, unable to realize remote deployment.
Two, the wiring is convenient, low cost
Center point:
NVR only then 1 cable wiring, installation can be completed, and access all monitoring points all control signal; and DVR for each monitoring point cloth video, audio, control and alarm of multiple cable. So NVR in the center of wiring and maintenance is very simple, convenient

Monitoring point:
Monitoring of NVR network hard disk video recorder system was a IP front end, and therefore only 1 cable wiring can be completed, and through the IP network access center of NVR; and the front end of the DVR system for analog devices, each monitoring front-end to the center need to video, audio, control and alarm multi-channel signal cable. Therefore, the front wiring NVR system is very simple, and the wiring cost is very low, the existing network

The use of PoE technology, NVR network hard disk video recorder system IP front-end equipment of the power supply can also through the Ethernet, and through the IP front output power signal, as other peripheral equipment power supply, which can be further simplified wiring. The front end of the DVR system must be single power supply, PoE power supply can not realize.
For monitoring point is not convenient wiring, wireless transmission of wireless IP front of subordinates can make monitoring signal, no wiring. The front-end DVR system for analog devices, not wireless deployment.
Three, installation is simple
An important advantage of DVR attract contractors is setup is simple, without complicated configuration. NVR network hard disk video recorder also has the advantage, but also more convenient.
Central NVR equipment and remote monitoring point IP front-end equipment only plugged in, turn on the power, then all processes can be automatically completed, including automatic search all front-end equipment, automatic NVR external display device automatic multi-picture display all monitoring points image using IP address allocation, front-end equipment

Therefore, NVR innovation realization network video monitoring system in the installation of plug-and-play. Project developers and users need not worry about network monitoring brings difficulty to its deployment.
1 ) connected, open the power supply cable
2 ) automatically search all IP front-end equipment, and dynamic allocation of IP address
3 ) automatically local screen all front-end display
Four, flexible and reliable storage
One of the features of convenient DVR video storage also attract engineering business. Video storage characteristics of convenient NVR also have highly integrated, the local hard disk, can achieve centralized storage, but also can satisfy the demand for mass storage by expanding peripheral storage devices.
Further, the IP front-end equipment NVR system can also support the front storage through the deployment, storage mode to provide a more flexible, and can realize the storage and driving recorder center storage backup of storage reliability requirements, meet the application requirements are very harsh. While the front end in the DVR system for analog devices, unable to realize the front storage.
Five, security and encryption
Many people think that the network video monitoring system is not safe, in fact, NVR is more secure than DVR. In the NVR system, IP front-end upload stream can be AES encryption on the stream, intercepted even in the network, also cannot decode. The analog video, DVR front-end upload audio signals without any encryption mechanism, can easily be intercepted and displayed. In addition, authorization, the telecom user authentication mechanism, NVR can effectively prevent illegal user login system.
