PREFACE

The Digital Disk Recorders WJ-HD316/309 are designed for
use within a surveillance system and are a combination of a
hard disk recorder and a video multiplexer (16-input for the
WJ-HD316, 9-input for the WJ-HD309).
The digital hard disk recorder is a recording device using a
hard disk drive to record camera pictures instead of using
videotapes so that pictures recorded by repeated overwrit-
ing will not experience deterioration of the recorded picture
quality. Up to 16 cameras can be connected to the WJ-

FEATURES

Various Recording Functions
• Multi-Recording
It is possible to perform multiple recordings using a sin-
gle digital disk recorder even if the operating environ-
ments are different, for example, recording pictures of
cameras in different places at different times.
• Schedule recording
It is possible to perform recording automatically at a
scheduled time on a designated day of the week.
Schedules can be set on each camera.
• Emergency Recording
In the case of an emergency, emergency recordings
will be given a higher priority than other recording
modes by operating an external switch.
• External Timer Recording
It is possible to perform recording automatically using
an external timer.
• Event Recording
At an event occurrence, such as when an alarm signal
is supplied, the recording mode (quality and recording
rate) can be changed to high quality to record pictures.
• Motion Detection Function (VMD)
It is possible to start recording automatically when
motion is detected in a shooting area.
Frame Switcher Function
• It is possible to display pictures of four or more cam-
eras on a single monitor (multi-screen) splitting the
monitor screen into 4, 7, 9, 10, 13, or 16 sections using
the WJ-HD316, and into 4, 7, or 9 sections using the
WJ-HD309.
