H.264 CCTV DVR Hard Drive Calculator for iDVR-PRO

This hard drive calculator is for iDVR-PRO H.264 CCTV / HD security camera DVRs. It is used to estimate the number of days of video surveillance recording that different sized hard drives will provide given the number of cameras, resolution, frame rate, and hours per day that your security cameras will be recording. Although this calculator is made for iDVR-PRO DVRs, the amount of hard drive space usage is fairly standard for any H.264 video codec DVR, so this can be used as a guideline for any model. Of course, the calculator is most accurate for the iDVR-PRO DVRs that it was developed for. You can find our video storage calculator here.

Using the above calculator, select the hard drive size, video quality, video resolution, frame rate, and number of cameras that you intend to use. If you plan on using motion detection recording, scheduled recording, or alarm based recording, please be sure to estimate the number of hours of recording per day. If your security cameras will be recorded continuously, be sure to select 24 hours per day.
