DISK ALLOCATION/DISK PARTITIONS
The hard disk(s) is partitioned into four sections. It is extremely important to properly configure
the drive(s) on setup. Use this screen to specify how much space will be devoted to the
different recording modes.
Refer to Tables A, B, C, and D to help decide how to allocate disk space.
NOTE:
If you plan on doing any of these—schedule recording, motion detection recording, event
and alarm recording, and data exception recording—you must program them before doing disk allo-
cation. If you have not programmed any of these, you will get a “None Set” error message when you
try to allocate disk space.
APPROXIMATE HARD DISK SPACE TABLES
The numbers of days listed in the tables below are for total hard disk space. This combines all
disk partitions: scheduled, motion, event, and alarm.
(The following tables are approximations. For a more precise estimate, refer to the
Disk Space
Estimate Calculation
section.)
The figures above are for all eight cameras running at 1 IPS (images per second) continuously
for 24 hours a day, 7 days a week. Reducing the recording schedule times will reduce the
GB/day and increase the number of days.
NOTE:
Values indicating video storage capacity are estimates only. These estimates are to be
used as guidelines in determining proper hard drive requirements. Many user selectable factors
such as image quality, recording rate, image content/motion, and video noise will all affect the total
amount of video that can be stored on a hard drive. These video storage duration estimates will vary
based on actual use. These estimates are not an implied or expressed guarantee of actual perfor-
mance.
