If system software of needs be upgraded, please contact your JVC dealer. This section shows you how to operate and manage 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 image size, recording rate, and 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 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) operation, please calculate recording time using the table below in accordance your requirement. For a NTSC unit, for example, if the unit is set to record images with BEST quality at 60 fps record rate, normally a 80GB hard-disk drive will be filled in 15 hours (See the gray area table). If total capacity of 240GB hard-disk drives is in use under the same refresh and picture quality, it will be filled in 45 hours (3 times the rate of a 80GB 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, record speed of the multiplexer must be correctly adjusted to match DVR and set MULTIPLEXER option on the setup menu to ON. This can be done by either of methods detailed below. Connect SW. OUT terminal in 9-PIN D-SUB connector on rear panel of DVR to the multiplexer�s trigger contact. The DVR will provide timing signal (Negative/Falling) to the multiplexer. Thus, if DVR changes recording speed, multiplexer will automatically adjust the record to match. A 2-hour 4-hour timing signal NTSC or a 3-hour and 6-hour one in PAL is constantly negative/falling.
