Preface
Features
The Network Disk Recorders WJ-ND300A series are designed for use within a surveillance system, and perform
recordings and playbacks pictures from network cameras in the system.
The network disk recorder is a recording device using a hard disk drive to record camera pictures instead of using
video tapes so that pictures recorded by repeated overwriting will not experience deterioration of the recorded pic-
ture quality.
Up to 32 cameras can be connected via a network and it is possible to record their camera pictures. It is possible to
perform the settings or operate the WJ-ND300A (this unit) using a web browser installed on a PC connected to a
network. Up to 8 PCs (web browsers) can access this unit concurrently and it is possible to perform the settings and
operate this unit.
WJ-ND300A is the generic name of the network disk recorders WJ-ND300A series.
Various Recording Functions
• Multi-recording
It is possible to perform multiple recordings using a single network 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 a week. It is also
possible to perform recording at a different recording rate according to time range.
• 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 an alarm signal is supplied, the recording mode (quality and recording rate) can
be changed to high quality to record pictures.
Downloading/Transmitting Images
It is possible to download (save) the currently displayed image in the web browser window onto the hard disk of a
PC. By establishing an FTP server, it is possible to transmit images to the designated FTP server periodically. When
an event occurs, it is possible to transmit images from the camera installed in the place where the alarm occurred.
Event Notification Function
When an event occurs, it is possible to send e-mails to designated addresses to notify of the event occurrence.
It is also possible to send an e-mail with an image recorded when the event occurred.
Security Function and Reliability
• User authentication function (registration of ID and password) allows users access to predetermined selection of
the available functions. Up to 32 users can be registered.
• Host authentication function restricts devices from operating this unit if their IP addresses are not registered.
• If a hard disk crashes, the RAID 5 function prevents any recorded pictures loss.

Terms Used in these Operating Instructions
HDD
Refers to a hard disk drive (mass storage medium). The unit records camera pictures on a hard disk rather than on
video tape.
Recording rate (ips, I-Frame)
Refers to the unit that determines the smootheness with which the recorded images are played back. ips is used to
express the number of frames recorded per second. The higher the number, the smoother the movement, but the
available recording time becomes shorter. I-Frame is used to express the refresh interval set on the camera.
Resolution
Resolution refers to the degree of fineness and quality of the camera pictures recorded by this unit. This unit dis-
plays the resolution in number of dots. For example, if the number of horizontal dots is 720 and the number of verti-
cal dots is 480, the display reads 720 x 480. 
M-JPEG
A video codec that compresses video fields from the camera into independent JPEG images sequentially by query
from the unit.
Network load will be reduced comparing with the method that obtains JPEG images independently from the camera.
However, the transmission rate will fluctuate depending on the state of the camera.
Some cameras phrase this video codec as just JPEG.
Manual recording
Function for starting and stopping recording manually by clicking the recording button or recording stop button.
Schedule recording
Function for starting and stopping recording automatically at a preset time.
Event recording
Function for starting recording automatically when an event occurs.
Event recordings are divided into pre recordings (pictures before the event occurs) and post recordings (pictures
after the event occurs).
Emergency recording
Function for performing priority recording in emergency situations, etc. through an external switch connected to the
unit.
SD memory recording/SD memory data
Function featured in some Panasonic’s cameras that saves images on the SD memory card on the camera when
communication with the camera failed in the period set for the schedule recording of this unit. Images saved by the
SD memory recording are described as SD memory data on these operating instructions. The recording time of SD
memory data will be displayed based on the clock of the camera. 
						

							6
External recording mode
Function for changing the programmed time schedule through an external switch connected to the unit.
Event
An event is a phenomenon which triggers a specific operation (event operation) in the unit. Events are divided into
terminal alarm, command alarm, and site alarm. 
Event Action
Event action refers to a specific operation performed when an event occurs. Event operations are divided into ALM
(Alarm Mode), ADM (Activity Detection Mode), and are selectable. In ALM, the occurrence of an event is announced
by screen display, LED, or buzzer (Alarm Operation). In ADM, the occurrence of an event is not announced, but the
unit starts event recording, performs the preset operations, and enters the event into the event log. In OFF mode,
the unit only enters the event into the event log. 
Sequence
Sequence refers to automatically changing the displayed camera picture in a preset sequence. Sequence display is
possible while the unit displays live pictures.
Electronic zoom
Function for enlarging live and playback pictures. While the camera uses the camera zoom function to enlarge pic-
tures, the electronic zoom function enlarges the picture electronically in the unit and displays it.
Camera control
Camera control refers to controlling the functions of the combination cameras connected to the unit. These functions
include Pan/Tilt, Zoom, Focus, Brightness, Preset Operations (moving the camera to a preset horizontal/vertical
position), and Auto (for example, automatic panning).
A-B repeat playback
Function for playing back repeatedly between a set start point (A) and an end point (B) in playback mode.
HDD safety mode
Function for turning off the power supply to the HDD to prevent damage of the HDD due to vibration and shock if the
unit is mounted in or dismounted from the rack with the power turned on.
Disk config
When an HDD is replaced, removed, or added, the HDDs need to be newly configured. Disk config refers to the
menu for performing these HDD settings.
RAID (RAID5)
This stands for Redundant Arrays of Inexpensive Disks. It refers to a technology to implement a high-speed large-
capacity and high-reliability disk unit by distributing access to multiple HDDs. If trouble occurs in one of the HDDs,
the data on the faulty HDD can be recovered based on the error correction data recorded on the other HDDs.
(RAID5 is used when 3 or more HDDs are connected. If trouble occurs simultaneously in 2 or more HDDs, the data
of the faulty HDD cannot be recovered.)
System Administrator
This refers to a person who has the responsibility and authority to operate the unit and perform settings.

Restrictions when operating MPEG-4 images
There are following restrictions when MPEG-4 is selected for the image compression method on the setup menu
(advanced) (NW camera setup under Camera).
1. When displaying live images
qBlack screen may be displayed for the first few seconds (
*) when the following operations are performed while
displaying live images.
•When MPEG-4 live images are displayed (by switching camera channel, etc.)
•When MPEG-4 image is enlarged (or when enlarged MPEG-4 image is resized to the original size)
wIt may take several seconds (
*) for refresh interval of MPEG-4 image when displaying images on a 4-screen.
Example: When 3 seconds is selected for the refresh interval on the camera, MPEG-4 image will be refreshed
in 3 seconds intervals.
eWhen QUICK is selected for REC Type under REC Setup of the setup menu (QUICK), MPEG-4 live image
will not be displayed. To display MPEG-4 live image, select ADVANCED.
2. When displaying images sequentially
When MPEG-4 is selected for the image compression method of the camera selected for a camera channel on the
setup menu (advanced) (Sequence Setup under Camera), the respective sequence step will be skipped.
3. When playing recorded images
qDisplayed playback time may be fast for several seconds (
*) when the following operations are performed while
playing recorded images
•When MPEG-4 recorded images are played (by changing camera channel, etc.)
•When MPEG-4 image is enlarged (or when enlarged MPEG-4 image is resized to the original size)
(When operating to zoom in/out a paused MPEG-4 recorded image, image of several seconds later than the
displayed image may be enlarged.)
•When the [PLAY] button is clicked again while playing MPEG-4 image
•When the first frame is displayed by clicking the [NEXT IMAGE] button during pausing
wPlayback may be performed in several seconds intervals (
*) when the following operations are performed while
playing MPEG-4 image.
•Reverse playback
•Fast playback/fast reverse playback
•Reverse frame playback

4. When recording images
qTime and date displayed on the recording event list (actual start time of recordings) may not exactly indicate the
actual time of recording trigger (event occurrence time, start time of the schedule recording, etc.), and also the
recording duration may be shortened for seconds worth two times of the refresh interval set on the camera.
Example:When the set recording duration and the set refresh interval of the camera are 10 seconds and 1 sec-
ond respectively
10 – (1 x 2) = 8 (sec)
The minimum actual recording duration is 8 seconds.
wWhen pre-event recording is set to be performed, pre-event recording duration may be longer than the set dura-
tion.
Example:Depending on the size of the image data, pre-recording duration may be around 10 seconds even
when setting 5 seconds for the pre-event recording duration.
eWhen QUICK is selected for REC Type under REC Setup of the setup menu (QUICK), MPEG-4 images will
not be recorded. To record images in MPEG-4 format, select ADVANCED.
5. When copying images
Copying may start from a point several seconds (
*) later than the designated start time when copying MPEG-4
images. To copy the desired images for sure, designate start time several seconds earlier than the time when the
desired images are recorded, and set time range for copying longer than the refresh interval set on the camera.
6. When downloading recorded images
Download of recorded images may start from a point several seconds (
*) earlier than the designated start time. Set
time range for download longer than the refresh interval set on the camera.
7. When transmitting images recorded at an event occurrence to the FTP server
Duration of images to be transmitted to the FTP server, which are recorded at an event occurrence, may not be
exactly the same as the duration set for Duration-Pre and Duration-Post. Set Duration-Pre and Duration-Post
longer than the refresh interval set on the camera.
8. Other
MPEG-4 images will not be attached to alarm mails.
Even when images are to be transmitted to the FTP server periodically, MPEG-4 images will not be transmitted.
*: Time (seconds) differs depending on the refresh interval set on the camera (1 – 5 seconds). To shorten time lag,
set the refresh interval on the camera shorter. Refer to the operating instructions of the camera for how to config-
ure the refresh interval.
