Recording Duration Data
Note: Use the AurorAcorD Calculator, found on the AurorAcorD CD, to calculate changes to your recording
duration based on sensitivity, quality and other recording parameters. Refer to the AurorAcorD CD
Programs section of this manual for more detail.
The tables below illustrate the ramifications of each Quality and Sensitivity setting on record duration and
hard drive usage. The first table provides a consumption rate in GB/day based on assumptions of 8 hours of
non-continuous scene activity and a frame rate of 15 fps. The numbers listed in the tables are guidelines only
and can vary greatly based on the amount of scene activity.

The second table shows the estimated number of days that the AurorAcorD can be expected to record before
hard drives of various sizes are filled. “Max” frame rate changes from 18 fps to 24 fps, depending upon the
synchronization of all cameras in the system. All setting in this table are based on a Sensitivity setting of
“Highest” and are worst case. By changing Sensitivity from “Highest” to “Normal”, you may experience
significantly longer recording durations in areas of little or no activity. “Activity” is defined as any motion in the
scene; for example, moving people or vehicles, swaying trees, swinging signs or CRT monitor scan.
Refer to the Programming and Quick Programming sections for more information.
