How to Optimize NVR / DVR StorageBy John Honovich, Published Jun 04, 2008, 08:00pm EDT
Megapixel cameras have brought renewed interest in measures to maximize NVR/DVR storage duration and use. Cost is a big factor as the potential storage needed could increase by 10x or more than historical standards. Understanding what options and measures are available is becoming increasingly important to selecting NVRs/DVRs and designing IP video systems. This report surveys common measures used to maximize strorage duration and use.
Recently, interest has risen in new product categories that specialize in optimizing storage use.
Frost and Sullivan has recently reviewed "Video Lifecycle Management Solutions" [link no longer available] and identified TimeSight Systems [link no longer available] as a "young leader" in this space. The release does a good job of identifying the problem and highlighting one potential solution.
As almost all video systems have numerous measures to optimize storage use, I recommend that integrators and end users focus on utilizing existing measures in leading systems. Video system developers have been building tools for years to address storage optimization. Most will be best served by selecting a video management system based on features optimized for your specific security needs. Significant and comparable storage optimization can generally be accomplished on most mainstream NVR / DVR systems.
How Do I Optimize Storage?
This report reviews 8 commonly available storage optimization functions available on mainstream NVR /DVR systems. Though not every system has all of these features, all systems offer a number of them, providing strong storage optimization.
Here is the list:
- Basic Motion Analytics
- Advanced Video Analytics
- Motion Exclusion Zones
- Data Aging
- Recording Schedule
- CODEC Selection
- Dual Streaming
- Storage Clusters
