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-
HD316 directly (up to 9 cameras to the WJ-HD309) and it is
possible to record their camera pictures. It is also possible
to display four or more camera pictures on a single monitor,
to switch camera pictures, and to operate cameras using
this unit.
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.
While monitoring a multi-screen, each camera picture
will be displayed as a moving image.
Remote Operation via Network
It is possible to operate this unit using a PC connected to a
LAN (Local Area Network) or the Internet with the featured
network function.
Security Function and Reliability
• Authentication function (registration of ID and pass-
word) allows users access to a predetermined selection
of the available functions. Up to 32 users can be regis-
tered.
• If alteration of a recorded image data is made for any
reason, the alteration alert function will announce it.
• If a hard disk crashes, the backup function
*1
, the mirror-
ing function
*2
and the RAID 5 function
*3
prevent any
data loss.
*1
: Only when the recommended DVD-RAM drive, DVD-R
drive or CD-R drive is used
*2
: The mirroring function does not work with an external
hard disk drive such as an extension unit.
*3
: To use the RAID 5 function, an optional extension unit is
required.
Transmission with Coaxial Cable, PS·Data and
RS485 Compatible
• It is possible to control a Panasonic combination cam-
era such as the WV-CS850 using only a coaxial cable
but not other devices. Using a coaxial cable also com-
pensates for transmission loss.
• It is easy to establish the surveillance system by con-
necting a PS·Data compatible system controller and
peripherals.
