安防大数据的挑战据IDC预测,2020年全球的数据总量将达到35ZB,并以每两年翻一番的速度在急速的增长。大数据时代的数据不仅仅是数据总量的庞大,同时也是种类的庞大。安防行业有着海量的视频、图片数据,一个大型城市每天产生的数据就可以达到1PB,同时还有飞速增长的特征数据,包括卡口过车数据、人脸抓拍数据、报警数据等等。繁多的数据种类、PB级的数据量、低价值密度的视频数据、快速的数据更新处理需求,这些特性都预示着安防行业已经进入大数据时代。
Security Big Data Challenges According to IDC forecasts, the global data volume will reach 35ZB by 2020, and will rapidly increase at a rate of doubling every two years. Big data era data is not only the huge amount of data, but also a huge variety. Security industry has a huge amount of video, image data, a daily data generated by a large city can reach 1PB, along with the rapid growth of the characteristics of data, including the bayonet car data, face capture data, alarm data and so on. A wide range of data types, petabytes of data, low value-density video data, and fast data update processing requirements all signal the security industry’s entry into the big data age.
