4. BASIC OPERATIONS
This section shows you how to operate and manage the DVR when it gets in the way.
4.1 Configuring Recording Settings
Recording Time settings (Recording Rate and Picture Quality Setting)
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 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 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 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).
