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
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.
