2. Calculating Storage Required

As you have had an opportunity to review compression, resolution, quality, and speed of video, all these
factors are needed to intelligently calculate proper storage amount needed for each DVR unit or best
configure each video. Here is a simple mathematical formula for your convenience.
HDD Size Per Day by each Camera = number of frames per second X number of seconds in a day (1Day =
60X60X24) X size of image in bytes (see Table 2 Data size - Image Quality by Resolution on page 92).
With above formula here are some reference figures
