How Much Storage is Needed for Video Surveillance?

Author: John Honovich, Published on Aug 15, 2009

How much storage is needed for video surveillance is an important question for planning new system deployments and for determining total installation cost.

In the last few years, fears have increased dramatically that the amount of storage needed was exploding and that video surveillance systems would need 10 times or 100 times the amount of storage they historically used. Coming from a world where 250GB or 500GB DVRs was common, this created a lot of anxiety and questions.

Rules of Thumb

The following two metrics should provide a range:

  • 80% of surveillance cameras use between 60GB to 600GB of storage
  • 99% of surveillance cameras use between 6GB and 6TB of storage

Such broad ranges may seem surprising but there are a dramatic number of factors that influence video surveillance storage (see our calcuating storage report).

In this report, we examine a number of common scenarios to help you better understand whether you are likely to need 6GB, 60GB, 600GB or 6TB.

Fears Over-Stated

Despite the complexity, the good news, though, is that fear of explosive storage growth are unfounded. While more storage will be used per camera in the future, it will match the natural decrease in storage prices that happens continuously.

In this report, we project how changes in storage pricing, cameras deployed, CODECs used and evidence quality required will impact storage utilization.
