画面处理器是监控系统的上一个纪元——模拟时代的标志性产物,在DVR数字硬盘录像机诞生前的十年间,矩阵切换器和画面处理器分别牢牢占据了监控系统的高端和低端市场,在那个年代,与矩阵动辄数万的价格相比,画面处理器则价廉实惠得多,因此成为早期民用安防系统的“标准配置”而被大量使用。直至现在,我们还可以看到由摄像机、画面处理器、VCR磁带式录像机组成的监控系统一直在对画质要求不高的项目中充当着主力。在今天看来,了解画面处理器的这段历史如同打开了安防产品发展史的画卷,让我们从中细细品味监控产品的技术演进过程。
Screen processor is the last era of monitoring system - a landmark product of the analog era, in the ten years before the birth of DVR digital hard disk video recorders, matrix switchers and picture processors, respectively, firmly occupy the high-end and low-end market monitoring system At that time, the picture processor was much cheaper than the tens of thousands of matrices, making it the “standard configuration” for early civilian security systems, which was widely used. Until now, we can also see that the surveillance system consisting of a video camera, a picture processor and a VCR tape recorder has always been the mainstay in projects where quality is not critical. From today’s perspective, understanding this history of the picture processor is like opening the picture of the history of the security product development, let us savor the technological evolution of monitoring the product.
