Panasonic WJ-HD316 User Manual

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 cause deterioration of the recorded picture qual-
ity. Up to 16 cameras can be connected to the WJ-HD316

directly (up to 9 cameras to the WJ-HD309) and it is possi-
ble 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.

It is possible to perform multiple recording 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.

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.

In case of emergency, emergency recording will be
given a higher priority than other recording modes by
operating an external switch.

It is possible to perform recording automatically using
an external timer.

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.

It is possible to start recording automatically when
motion is detected in a shooting area.

• 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.

It is possible to operate this unit using a PC connected to a
LAN (Local Area Network) or the Internet by the featured
network function.

• 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 there

being 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.

• 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.
