Pelco C690M-E operation manual Disk ALLOCATION/DISK Partitions, Approximate Hard Disk Space Tables

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.)

Table A. DX2008 Recording Times at Different Quality Settings

Quality	GB/Day	160 GB HDD	320 GB HDD	480 GB HDD	640 GB HDD
		Days	Days	Days	Days
Quality 8	28	5	11	16	22
Quality 7	21	7	15	22	30
Quality 6	18	9	18	27	36
Quality 5	14	11	22	34	45
Quality 4	11	14	28	42	56
Quality 3	9	17	34	52	69
Quality 2	7	22	45	67	90
Quality 1	5	32	64	96	128
Quality 0	3	45	90	135	180

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.
