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 80GB 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
requirements. For an NTSC unit, for example, if
the unit is set to record images with the
BEST
quality at a
30 Frame/Sec
record rate, normally a
80GB hard-disk drive will be filled in 38.7 hours
(see the gray area in the table). If the total
capacity of 240GB hard-disk drives is in use
under the same refresh rate and picture quality, it
will be filled in 116.1 hours (3 times the rate of a
80GB hard-disk drive).
NOTE:
Recording times on the tables below are
estimated.
For the total available time of the
current recording configuration
, refer to the
system information of the DVR. (Please refer to
section 2.3 system information for more
details.)
