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 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 60 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 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).
Set up the REC Time Mode when a multiplexer is connected
If a multiplexer is connected, for optimum image recording and playback, the record speed of the
multiplexer must be correctly adjusted to match the DVR and set the MULTIPLEXER option on the
setup menu to ON. This can be done by either of methods detailed below.
(1) If an IDVIEW multiplexer is connected for use, you can program the REC time mode of the multiplexer
by referring to the table below (each refresh rate refers to one REC time mode).
(2) For a multiplexer other than IDVIEW. Please, Connect the SW. OUT terminal in 9-PIN D-SUB
connector on the rear panel of the DVR to the multiplexer's trigger contact. The DVR will provide
the timing signal (Negative/Falling) to the multiplexer. Thus, if the DVR changes the recording
speed, the multiplexer will automatically adjust the record to match. A 2-hour and 4-hour timing
signal in NTSC or a 3-hour and 6-hour one in PAL is constantly negative/falling.
