Choosing Sensitivity & Quality Settings for Most Recording Time and/or Least Hard Drive Usage
MENU

Set Sensitivity to Highest. This will
enable you to test the Quality settings
more effectively, as the update will not
be dependent upon motion.
Change the quality
for camera 1 and
observe the quality
of the camera video.
Change the quality setting and view the video at the
new setting. Repeat for all five settings: Lowest, Low,
Normal, High, Highest and choose a setting for this
camera. The Normal setting is the factory default.
Select the next camera and
repeat the procedure.
Continue until Quality is set
for all cameras.
The following tables 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 settings 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, moving or swinging signs or CRT monitor scan.

Note: Recording and playback stops.
Recording is simulated during loopback
mode so that you can set record quality.

Sensitivity was set to Highest in a previous step.
Observe the video update with motion in the
field of view of any camera. Note that
Sensitivity is a global, not per camera, setting.
Change the Sensitivity setting
and observe the video again.
Repeat for all settings and
choose the optimal setting.
Note: Disable Loopback Mode after you have made
Quality and Sensitivity settings. It is important to realize
that if Sensitivity is set to Highest and Normal Rate is
not set to Off, recording will take place continuously.
