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: DVR0414 supports 30 frames per second recording in total for the whole machine. Users may chose to
record a single channel in real time (30 fps) or split the system resources evenly among several channels. Under
the LIMITED mode, every one of the four cameras will be recording at a fix rate of 7.5 fps. Under the AUTO
mode, depending on the number of channels that are recording, a channel can take 30, 15, 10 or 7.5 fps.
Following are storage calculation guidelines (in the number of Days):
Image
Quality 30F/S Days
80G 1(128kb/s) 128kb/s 61
2(256kb/s) 256kb/s 30
MP4(CBR) 3(384kb/s) 384kb/s
20*
4(512kb/s) 512kb/s 15
5(768kb/s) 768kb/s 10
6(1024kb/s) 1024kb/s 8
* This reads that with an 80G harddisk, at CBR (constant bit rate) 30 fps and Image Quality 3, DVR will be able
to record 20 days.
