This section shows you how to operate and 

manage the DVR when it gets in the way.   

   

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 

requirement. For an 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).   

 

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 the two 

methods detailed below. 

 

(1) If an APPRO 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 APPRO, please 

connect the SW. OUT terminal in the 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.
