PREFACE The Digital Disk Recorders WJ-HD316A/309A 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-HD316A, 9-input for the WJ-HD309A). 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 overwriting will not experience deterioration of the recorded picture quality. Up to 16 cameras can be connected to the WJ- HD316A directly (up to 9 cameras to the WJ-HD309A) 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 single digital disk recorder even if the operating environments 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 cameras on a single monitor (multi-screen) splitting the monitor screen into 4, 7, 9, 10, 13, or 16 sections using the WJ-HD316A, and into 4, 7, or 9 sections using the WJ-HD309A. While monitoring a multi-screen, each camera picture will be displayed as a moving image. 8 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 password) allows users access to a predetermined selection of the available functions. Up to 32 users can be registered. • 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 mirroring 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 camera such as the WV-CS850 using only a coaxial cable but not other devices. Using a coaxial cable also compensates for transmission loss. • It is easy to establish the surveillance system by connecting a PS·Data compatible system controller and peripherals.

PREFACE
The Digital Disk Recorders WJ-HD316A/309A 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-HD316A, 9-input for the WJ-HD309A).
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-
HD316A directly (up to 9 cameras to the WJ-HD309A) and
it is possible to record their camera pictures. It is also pos-
sible 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-HD316A, and into 4, 7, or 9 sections using the
WJ-HD309A.
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.
