3. OPERATIONS
This section shows you how to operate and
manage the DVR when it gets in the way.
3.1 Configuring Recording
Settings
Recording time will vary depending on the image
size, recording rate, and the capacity of the
hard-disk drives. Generally, the DVR comes with
a built-in hard-disk drive for continuous recording
from one to four weeks under most recording
conditions. The table below shows the possible
recording times based on a 20GB hard-disk drive
at certain refresh rates and the corresponding
image quality. With one or more hard-disk drives
in operation, please calculate the recording time
using the table below in accordance with your
requirement. For an NTSC unit, for example, if
the unit is set to record images with
BEST
quality
at a
30 fps
record rate, normally a 20GB
hard-disk drive will normally be filled in 3.7 hours
(see the gray area in the table). If the total
capacity of 80GB hard-disk drives is in use under
the same refresh rate and picture quality, it will be
filled in 14.8 hours (4 times the rate of a 20GB
hard-disk drive).
NOTE:
1. Recording times on the tables below are
estimated. For the actual available recording
time of a recording configuration, refer to the
system information of the DVR. (Please refer to
section 2.3 system information for more
details.)
2. There is no audio function at the refresh rate
in NTSC: 1.2 fields/sec ~ 1 fields/ 16 sec. There
is no audio function at the refresh rate in PAL:
1.4 fields/sec ~ 1 fields / 16 sec.
