DVR成为当前主流视频监控最必配设备DVR has become the most necessary equipment for mainstream video monitoring

　　从最初的MPEG1、CIF到现在的H.264、D1，价格一路跳水，现在D1机的价格甚至低于当年CIF机的价格。当前，即便DVR技术已发展得相当成熟、市场竞争十分激烈，但不可否认的是，DVR已成为主流视频监控最必配的设备。就市场现状，不管何种规模的视频监控应用，DVR仍以其较低的成本投入、稳定的本地存储、具小路数视频切换和分割显示功能、宜长时间记录等诸多特点，仍稳据相当的市场份额。
Prices have plunged from MPEG1 and CIF to h.264 and D1, and now the price of D1 is even lower than the price of CIF back then. Currently, even though DVR technology has developed quite mature and the market competition is fierce, it is undeniable that DVR has become the most necessary equipment for mainstream video monitoring. Market situation, no matter what the size of the video monitoring application, DVR still with its lower costs, the stability of the local storage, small ways on video switching and display function, appropriate records for a long time, and many other features, is still stable, according to a considerable market share.
 

　　DVR将怎样发展呢?就当前应用的回答是模数混合、超强网传、整合平台软件、HDMI高清数字接口。现在新型DVR，就符合这个趋势，因此主流厂商纷纷衍生开发出混合型HDVR、NVR。其特点就是能同时接入数字和模拟信号，支持网络管理前端网络设备，并实现录像管理和高清回放。以此支持现阶段大量模数并存的状况，能有效保护用户前期投入。但依据发展趋势，DVR终究会被只支持网络信号的NVR取代，上述的DVR演变过程都始终离不开芯片技术不离不弃的一路伴行。
How will DVR evolve? For current applications, the answer is a mix of modules, a strong network, integrated platform software, and HDMI hd digital interfaces. The new DVR is in line with this trend, so mainstream manufacturers have developed hybrid HDVR and NVR. Its characteristic is to be able to access both digital and analog signals at the same time, support network management front-end network equipment, and realize video management and hd playback. This supports the current situation of large number of modules coexist, can effectively protect the user's early investment. However, according to the development trend, DVR will eventually be replaced by NVR which only supports network signals. The above evolution process of DVR is always inseparable from chip technology.
 

　　所以说，新型的DVR，或说HDVR、NVR，其显著特点是能通过千兆网口或多网络口，配合强大的CPU，具有强大的网传性能;或其还整合了软件平台和前端设备管理、视频转发、视频存储管理等多种功能，从而将进一步简化现有监控系统的组成。且传统的显示输出，如S端子、BNC、VGA等接口已无法满足高质量显示的要求，所以HDMI数字接口也逐渐成为了新型DVR的主流配置。
Therefore, the new DVR, or HDVR, or NVR, has the remarkable feature of being able to pass through gigabit or multi-network ports, with powerful CPU, and has strong network transmission performance. Or it also integrates multiple functions such as software platform and front-end device management, video forwarding, video storage management and so on, which will further simplify the composition of existing monitoring system. Moreover, the traditional display output, such as S terminal, BNC, VGA and other interfaces, has been unable to meet the requirements of high-quality display, so HDMI digital interface has gradually become the mainstream configuration of the new DVR.
 

　　同时，DVR已表现出强烈的定制化应用趋势，比如ATM机DVR要根据ATM机内部空间和支持银行特殊功能的设计;车载DVR则要满足车辆运行环境下的高温、高湿、强振、强电磁干扰等要求;针对司法检察系统，希望DVR具备多光盘同步刻录、画中画录像等特色功能。所以说行业专用也极大地推动了DVR及芯片技术和市场的大发展。监控技术的发展趋势是“数字化、网络化、高清化、智能化”，而这一趋势在DVR的发展上得到了最有力的印证。
At the same time, DVR has shown a strong trend of customized application. For example, the DVR of ATM should be designed according to the internal space of ATM and support special functions of Banks. Vehicle DVR should meet the requirements of high temperature, high humidity, strong vibration and strong electromagnetic interference in the operating environment of the vehicle. In view of the judicial inspection system, DVR is expected to have the features of simultaneous recording of multiple optical disks and video recording of pictures and pictures. So industry - specific also greatly promote DVR and chip technology and market development. The development trend of monitoring technology is "digitization, network, high cleanliness and intelligence", and this trend is most strongly confirmed in the development of DVR.
