Analog Security Cameras DVR Storage Calculator

Use this calculator to determine just how much storage space you will need for your surveillance system.

Tips on how to use this tool

  • When entering the frames per second (fps) of the cameras, consider that residential and small-scale security customers usually choose to record between 7 and 15 fps. Higher fps is typically only needed for commercial applications.
  • When entering the number of hours that your system will record each day, consider that employing scheduled recording and/or motion detection can dramatically reduce this time.
  • The results will be in gigabytes (1000GB = 1TB).
