 This calculator can be used to determine just how much storage you will need based on how many days storage you want.

How many days of video do you want to store?  

Number of cameras recording?  

Number of frames per second you would like each camera to record?  

How many hours per day does your facility operate?  

How many days of the week does your facility operate?  

You will need approximately       of hard drive space to meet your storage needs.

  DVR Surveillance Tips:

  • 1 frame per second is the lowest frame rate recordable and 30 frames per second is the maximum which is real time
  • There is no real need to record in real time unless there are regulatory reasons as in case of government facilities or casinos
  • Recording at 1 frame per second is what traditional analog systems record
  • You can always rewind in high speed so the lower the frame rate the faster it is to playback an entire day
  • At 3 - 5 frames per second recording you will not miss any activity (remember this is per second)

  These are just estimates as a variety of conditions can substantially change the storage requirements.
