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 drive. 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 drive(s)
in operation, please calculate the recording time
using the table below in accordance with your
requirements. 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 be filled in 3.7 hours (see the
gray area in the table). If the total capacity of
80GB hard-disk drive 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 are estimated in the tables
below. For the actual available recording
time of a recording configuration, please
refer to the system information of the DVR.
(Please refer to section 2.3 system
information for more details.)
2. No audio function at the refresh rate in NTSC:
2.7 frames/sec ~ 1 frame/ 16 sec .No audio
function at the refresh rate in PAL: 2.7
frames/sec ~ 1 frame / 16 sec.
