DVR Storage Calculator for Analog Security Cameras

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

How to use this tool

  1. Enter the number of cameras on the system (typically 4-16)
  2. Enter the frames per second (fps) of the cameras. Typically customers choose to record between 7 and 15 fps. Over 25 fps is normally considered 'real time' but not needed for most applications
  3. Enter the type of encoding for your video.
  4. Enter the screen resolution you want for your video.
  5. Enter the number of hours that your system will record each day. Using scheduled recording and/or motion detection can dramatically reduce this time.
  6. Enter the number of days of storage you wish to maintain on the hard drive.
  7. The results will be in gigabytes (1000GB = 1TB).
