4. BASIC OPERATIONS
This section outlines the basic operating instructions for the DGR204.
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 80GB 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 requirement. For a NTSC unit, for example, if the unit is set to record
images with
BEST
quality at a
30 Frame/Sec
record rate, normally a 80GB hard-disk drive will be filled
in 15 hours (See the gray area in the table). If a 160GB hard-disk drive is used with the same refresh
rate and picture quality, it will be filled in 30 hours (2 times the rate of a 80GB hard-disk drive).
