随着全国各地“和谐社会、平安城市”建设速度的加快,每个平安项目监控点成千上万,甚至数十万,根据政府、公安部门的要求,平安城市监控录像资料至少保存15天以上。因此产生的海量数据是非常惊人的,采用传统的硬盘录像机DVR无法满足实际的需求,是不是DVR从此要退出在整个存储市场舞台? With the speeding up of the construction of a “harmonious society and a safe city” all over the country, thousands or even hundreds of thousands of monitoring points for each safe project are required. According to the requirements of the government and the public security department, safe urban surveillance video should be kept at least 15 Days or more. Therefore, the massive data generated is very alarming, using the traditional DVR DVR can not meet the actual needs, is not the DVR from this stage to exit the entire storage market?
