3.2.4.2. Recording Capacity
The EX4 DVR uses
MPEG-4 video compression to extend the recording time on
the hard drive. The recording time varies, depending on the settings for frames per
second (speed), resolution, and picture quality.
The picture quality option lets you determine the amount a picture is compressed
versus the amount of memory the picture takes up on the hard drive. Table 3-5
shows the range for the picture quality settings where setting 1 is the standard
quality and setting 6 provides the highest picture quality. A higher picture quality
(6) means lower compression and therefore a higher memory requirement. A
lower picture quality (1) means higher compression and a lower memory
requirement.
Table 3-6 to Table 3-9 show the estimated recording time in hours for four
different hard drives, from 40 GB to 160 GB. The tables show the estimated
recording time in hours with one camera at the different settings for frames per
second (FPS), resolution, and picture quality.
