PREFACE

The Digital Disk Recorders WJ-HD316/309 are designed for
use within a surveillance system and are combination of a
hard disk recorder and a video multiplexer (16-input for WJ-
HD316, 9-input for WJ-HD309).
Digital hard disk recorder is the 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 cause deterioration of recorded picture quality
anymore.

FEATURES

Various Recording Functions

• Multi-Recording
It is possible to perform multiple recording using a sin-
gle digital disk recorder even if operating environments
are different, for example, recording pictures of cam-
eras in different places in different time.
• Scheduled recording
It is possible to perform recording automatically at a
scheduled time on a designated day of a week.
Schedules can be set on each camera.
• Emergency Recording
In case of emergency, emergency recording 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, 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 monitor
screen into 4, 7, 9, 10, 13, 16 using WJ-HD316, and into
4, 7, 9 using WJ-HD309.
While monitoring a multi-screen, each camera picture
will be displayed as moving image.
Up to 16 cameras can be connected to WJ-HD316 directly
(up to 9 cameras to 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 cam-
era pictures, and to operate cameras using this unit.
Remote Operation via Network
It is possible to operate this unit using a PC connected to a
LAN (Local Area Network) or the Internet by featured net-
work function.

Security Function and Reliability

• Authentication function (registration of ID and pass-
word) restricts users available functions to be operated.
Up to 32 users can be registered.
• If alteration of a recorded image data is made by any
reason, the alteration alert function notifies it.
• If a hard disk clashes, the backup function

ing function and the RAID 5 function
data loss.

: 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's combination cam-
era such as WV-CS850 using only a coaxial cable but
other devices. Using a coaxial cable also compensates
transmission loss.
• It is easy to establish the surveillance system by con-
necting PS·Data compatible system controller and
peripherals.
