Analyzing and Anticipating Storage Usage
DW Spectrum provides a way to estimate and predict storage usage. This feature allows users to plan their systems
and store recorded data more accurately.
This data is displayed per Server and broken down by individual camera.
Some common ways this information can be used:
 Identify camera(s) that stream at extremely high bitrates
 Estimate amount of time that Server can store recording (Days and Hours)
 Understand the storage space that each camera consumes
 Predict the amount of time that Server can store recording if add X terabytes.
To access Storage Statistics for a Server:
1. Open the Server Settings.
2. Click on Storage Analytics:
 Camera – Camera Name
 Space – the amount of storage consumed by recordings from this Camera
 Calendar Days – the amount of recorded data that is available for this Camera. DW Spectrum uses special
algorithm to keep the same amount of time stored for different Cameras. However a user can set minimum or
maximum storage duration in days for individual cameras. See "Configuring Maximum and Minimum Recording
Time for Camera".
 Bitrate for the Last Recorded – the average bitrate of the camera. It is possible to specify the amount of time the
average bitrate is calculated for, by specifying it in the upper-right dropdown list (i.e last 5 minutes or last day).
