This section shows you how to operate and manage the DVR when it gets in the way.

3.1Configuring Recording Settings

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).

Note: 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 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.
