Preface
Features
Network Interface Unit WJ-NT304 is designed to capture images from analog cameras and compress the images in JPEG or
MPEG-4 files.
By connecting to a network (LAN) or the Internet, images and audio from the camera can be monitored on a PC via a
network.*
1
*1 It is necessary to configure the network settings of the PC and its network environment to monitor images and audio from
the camera on the PC.
It is also necessary that a web browser is installed on the PC.
• Video input signals from up to 4 analog cameras can
be converted to stream files (JPEG or MPEG-4 format),
and a system can be established in which MPEG-4
images can be monitored while recording JPEG
images.
• Interactive communication with audio (transceiver type)
is available.
• Transceiver type communication is established by
transmitting and receiving audio when a user controls
the receiver button and transmission button inter-
changeably.
Transmitting and receiving audio are unavailable at the
same time.
• Panning/tilting platforms and lenses of combination
cameras (option) can be controlled with coaxial com-
munication.
• The FTP backup function and recording of each log on
an optional SD memory card are available using the
featured SD memory card.*

Precautions
• Do not block the ventilation opening or slots on the
cover.
To prevent the apparatus from overheating, place it at
least 5 cm {2 inches} away from the wall.
• Do not drop metallic parts through slots.
This could permanently damage the apparatus. Turn
the power off immediately and contact qualified service
personnel for service.
• Do not attempt to disassemble the apparatus.
To prevent electric shock, do not remove screws or
covers.
There are no user-serviceable parts inside. Contact
qualified service personnel for maintenance.
• Do not expose the apparatus to water or moisture.
Do not try to operate it in wet areas.
Take immediate action if the apparatus gets wet. Turn
the power off and refer servicing to qualified service
personnel. Moisture can damage the apparatus and
also cause electric shocks.
• Built-in backup battery
Before the first use, charge the built-in backup battery
(lithium battery) by turning on the power for 48 hours or
more. If it is not charged enough, in a case where the
power goes down, the internal clock may keep bad
time or the operative condition may be different to that
before the electric power failure.
The built-in battery life is approximately 5 years as an
indication of replacement. (This is just an indication of
replacement. We are not providing any guarantee of the
built-in battery lifetime. Replacement cost of the built-in
battery is not covered by the warranty even if it needs
to be done within the warranty period.) Ask the shop
where you purchased the unit when replacement of the
battery is required.
Use this product for indoor use only.
Do not expose this product to direct sunlight for hours and
do not install the product near a heater or an air condition-
er. Otherwise, it may cause deformation, discoloration and
malfunction. Keep this product away from water.

• Parts of this product may deteriorate and it may shorten
the lifetime of this product when using in locations sub-
ject to high temperatures and high humidity. Do not
expose the product to direct heat such as from a
heater.
• Use this product at temperature within 5 °C to 35 °C 
{41 °F to 95 °F} and humidity below 90%. (When using
this product without turning the power off)
The input power source for this apparatus is 120 V AC,
50 Hz/60 Hz.Use only the supplied power cord or AC adapter.
Use the power cord that is suited to your locality.
Handle the appliance with care.
Do not strike or shake, as this may damage the product.
Failure to observe this may cause trouble. 
About the PC monitor
When displaying the same image on the PC monitor for a
long time, the PC monitor may be damaged. It is recom-
mended to use a screen-saver.
When an error is detected, the unit will restart automati-
cally.
This unit will restart when detecting an error caused by any
reason. The unit will be inoperable for around 2 seconds
after the restart just as when the power is turned on.
About SD memory card
• Before inserting a SD memory card into the SD memory
card slot, turn the power of the unit off. Otherwise, it
may cause malfunction or damage data recorded on
the SD memory card.
Refer to page 16 for descriptions of how to insert/
remove a SD memory card.
• When using an unformatted SD memory card, format it
using this unit.
Recorded data on the SD memory card will be deleted
when formatted.
If using an unformatted SD memory card or using a SD
card formatted with other device, the unit may not work
properly or performance deterioration may be caused.
Refer to the Network Setup Instructions (PDF) for
descriptions of how to register users.
• Use Panasonic’s SD memory card. Otherwise, the unit
may not work properly or performance deterioration
may be caused.
About the self-diagnosis function
When the unit malfunctions due to exogenous noise, etc. for
30 seconds or more, the unit will automatically reset and
will return to normal state. When the unit is reset, initializa-
tion will be carried out as when the power of the unit is
turned on. When the unit repeatedly resets, exogenous
noise level around the unit may be high and that may cause
malfunction. Contact your dealer for instructions.
Cleaning
Turn the power off when cleaning the unit. Otherwise it may
cause injuries.
