Storage Duration for Surveillance

Author: John Honovich, Published on Apr 15, 2012

How long should video surveillance be stored? 1 week, 1 month, 1 year? This is a fundamental question for security systems. Store for too short a time and you could lose critical evidence yet record too long and it could waste a huge amount of money.

In this report, we share in-depth survey results of security integrators from around the world, examining how long and why real world deployments choose to store surveillance video.

This is part of our unique series on storage fundamentals, helping users make the right decision on the surveillance designs. Related reports include:

The Average

The most common storage duration, by far is 1 month; The next most common is 2 weeks. The histogram below charts the breakdown of integrator responses:

While that's the big picture, we captured many nuances in our survey results, allowing us to answer important questions such as:

  • Why do customers choose a specific storage duration?
  • How does use of megapixel impact storage duration?
  • Do larger projects average lower or higher storage duration lengths?
  • How long are the longest storage durations?
  • What drives long storage durations?
  • What markets are most likely to have extreme storage duration requirements?
