3. Storage Matrix
The HDD Capacities and Recording lengths are determined by capacity of the installed HDDs and the selected
image level.
The following storage time is based on the average use for HDD space for single channel recording.
Note: Adjustable frame rates, from 1fs to 30f/s can be selected. User can choose based on own needs.
Using other than 30f/s (Real time), HDD (Hard Disk) space can be greatly increased.
Following are storage calculation guidelines (in the number of Days):
Img
Quality 30F/S 1-ch 4-ch 8-ch
80G 1(128kb/s) 128kb/s 61 15* 8

5(768kb/s) 768kb/s 10 3 1
6(1024kb/s) 1024kb/s 8 2 1
* This reads that with a 80G harddisk, at CBR (constant bit rate) and Image Quality 1, DVR will be able to
record 15 days for 4 camera inputs.
