近年来,随着安防、交通、监管等领域对视频显示质量的要求越来越高,高清IP摄像机正逐步取代传统模拟摄像机成为视频监控的主流,而DVR作为模数转化存储设备,由于其布线繁琐、使用限制大以及难以适应网络架构等因素,无法配合高清IP摄像机的使用。在此情况下,应运而生的NVR以其使用便捷,可以完全适应有线、无线等网络传输方式,直接通过数字视频流进行视频存储等优点,契合市场对于高清网络摄像机的发展,必将在更多的领域取代DVR成为主要视频监控系统。
In recent years, as the demand for video display quality in areas such as security, traffic and regulation is getting higher and higher, HD IP cameras are gradually replacing traditional analog video cameras as the mainstream of video surveillance. DVR, as an analog-to-digital storage device, Tedious use of restrictions and difficult to adapt to the network architecture and other factors, can not meet the use of high-definition IP cameras. In this case, NVR came into being, with its easy to use, can fully adapt to wired, wireless and other network transmission methods, directly through the digital video streaming video storage, etc., fit the market for the development of high-definition network cameras, will be more Many areas to replace DVR as the main video surveillance system.
