Abstract: In the design of video monitoring engineering, the video storage capacity depends on the number of video channels, storage days and the formats of video storage. However, these are all variables and each change of quantity must be recalculated. Aiming at the above problems, this paper develops a video monitoring storage capacity calculator by using VC++ environment program. A large number of tests and applications in railway engineering design show that the calculator has good robustness.

摘要： 在视频监控工程设计中，视频存储容量的大小取决于视频路数、存储天数以及存储格式。而视频路数、存储天数、存储格式全部都是变量，且每变化一个量都必须重新计算。针对上述问题，利用VC++环境程序，开发一个视频监控存储容量计算器。通过大量测试及铁路工程设计应用表明，该计算器具有很好的鲁棒性。
