　　• DVR板卡是音视频的采集和编码卡，NVR板卡是独立CPU或独立CPU+编码芯片的主机板

　　• DVR板卡通过PCI插卡方式和工控主机共同构成系统，NVR板卡独立自成系统

　　• DVR板卡相当于PC中的显卡模式，NVR板卡相当于PC中的主机板

　　• DVR板卡构成的插卡式DVR在稳定性方面弱于嵌入式DVR，NVR板卡形成的嵌入式NVR在稳定性方面不弱于嵌入式DVR

　　• 两者的主CPU大都采用X86体系，开放架构，便于开类视频应用

　　• DVR板卡通过模拟方式接入摄像机，NVR板卡可独立或同时接入模拟/网络摄像机

　　• DVR板卡是SDK+应用模式，NVR板卡是视频中间件+应用模式

　　• NVR板卡继承了DVR板卡的开放特性，但更为稳定

• DVR board card is the acquisition and coding card of audio and video, and NVR board card is the host board of independent CPU or independent CPU+ coding chip

• DVR board card forms the system together with the industrial control host through PCI card insertion, and NVR board card is a system independently

• DVR board card is equivalent to the video card mode in PC, and NVR board card is equivalent to the host board in PC

• the plug-in DVR formed by DVR board card is weaker than the embedded DVR in terms of stability, and the embedded NVR formed by NVR board card is not weaker than the embedded DVR in terms of stability

• the main cpus of both adopt X86 system and open architecture, which is convenient for open class video applications

• DVR board card is connected to the camera through simulation, and NVR board card can access the analog/network camera independently or simultaneously

• DVR board card is SDK+ application mode, and NVR board card is video middleware + application mode

• NVR board card inherits the open characteristic of DVR board card, but it is more stable

布线便捷，成本低中心点： NVR仅需接1根网线即可完成布线、安装，并实现所有监控点所有监控信号的接入;而DVR需要针对每个监控点布视频、音频、控制以及告警等多路线缆。因此NVR在中心布线以及维护上非常简单、便捷。监
车载DVR发展方向

近两年来，市场上出现了各种各样种类繁多的车载硬盘录像机(车载DVR)，作为传统嵌入式硬盘录像机的细分市场，车载硬盘录像机也迎来了诸多安防企业的亲睐。车载硬盘录像机继承了普通嵌入式硬盘录像机的网络化、智能化技术
从TV Decoder组件看960H的DVR设计

自从Sony于2010年宣告其自家的CCD Sensor与ISP(DSP)支持960画素以来，960H架构为CCTV模拟安防监控开启了一个新纪元。由于960H摄影机渐渐普及，使众多DVR厂商相继投入系统开发。笔者因涉足CCTV多年，并且较早接触960H领
