This digital recorder is able to record images captured by up to 16 surveillance cameras and audio received by up to 2
microphones to its hard disk. The recorder is equipped with the function to search for desired scenes by specifying the
recording dates as well as the simultaneous recording/playback function that allows playback even during recording. In
addition, using the split display function to display up to 16 camera images on one screen, you can view more than one
monitored area at the same time. This recorder facilitates to configure a monitoring system for constant surveillance.
Realizing long-term recording
By reducing the size of recorded video data using the newly developed video compression engine (MEPG 4 system), the
writing capacity of HDD can be saved about 50% (compared with our conventional models). In addition, this recorder is
designed to connect external HDD to expand its HDD capacity up to 16 TB (when using optionally available DX-ZD6UE). Due
to this, you can construct a long-term recording system to store data for 2 years, for example.
Simple operation and USB mouse connectable
By connecting a separately available USB mouse to the serial bus terminal on the recorder, you can easily control the
recorder and setting menus. For frequently used functions such as search and copy, the simple operation menu allows you
to operate them by simple procedure. This recorder is equipped with the on-screen help function. By clicking the help icon or
pressing the HELP button, you can view various information such as operation procedures on the screen.
DVD/CD drive for data copy integrated
Immediately after retrieving important reference data, you can copy the data to DVD/CD discs (DVD-R/DVD-RW, CD-R/CD-
RW) by the internal DVD/CD drive.
"One touch copy" for easy copying with one button press
The recorder is equipped with the function to copy still playback images to a USB memory device or DVD/CD disc with one
button press. You can select still images or moving images to copy. When selecting moving images, you can specify the
recording duration.
XGA output terminal integrated
You can connect a general PC display monitor to this terminal to use it as a surveillance monitor.
Motion detection search function
By designating certain areas such as doors and windows shown in recorded images as detection target areas, you can
search for recorded data containing scenes having variation (or motion) in those areas and display the beginning of such
data. This function is useful, for example, in searching for intruders into deserted places or scenes where someone painted
graffiti on the wall.
Personal information protection function
By setting passwords, you can classify the recorder operations into 3 levels. You can set a password for deleting data from
HDD to protect them from unauthorized access or to use this function as misuse prevention. The recorder is equipped with
the function to prohibit playback of data recorded before the number of days you specify (auto expiration setting), which
facilitates data management according to your operation standard regarding the data storage period.
Alarm notification of intrusion and system errors
When an alarm signal is input to the recorder from external body sensors or when an error is detected in the system,
the recorder notifies the designated personal computer via TCP/IP command or e-mail. The recorder is also capable of
transferring the alarm-recorded images that is triggered by an external alarm signal to the designated FTP server.

• Don't remove the outer covering of this unit.
• Don't place this unit close to other devices. They may interfere with each other, disturbing video and audio.
• Don't place this unit on a heat source. In addition, don't place this unit near a heat source because this unit has
ventilation openings in its sides and bottom. Otherwise the inside temperature may rise, causing a failure.
• When this unit is placed on or under the monitor, a failure may be caused, such as image disturbance and DVD/CD
disc ejection failure.
• Don't place a strong magnetic object near this unit. It may affect the images adversely and cause loss of recorded
data.
• Don't expose this unit to volatile substances such as insecticide or don't leave this unit in contact with rubber or plastic
products for a long time. Otherwise the surface of the product may deteriorate or the coating may come off.
• When this unit is placed directly on the waxed floor, the adhesion may increase between the floor and the non-slip
rubber pads on the bottom of the product, causing the floor coating to come off or be colored.
• The HDD and cooling fans are motor-driven parts. To ensure stable recording, it is recommended to replace them
every 30,000 hours of use as a guide assuming that the ambient operating temperature is 25°C. When replacing HDD,
also replace the vibration-proof rubbers at the screwed areas. (Note that this period is just for a guide of replacement
interval and isn't intended to guarantee the lifetime of the parts. They may be broken earlier because of shocks applied
to the product and ambient operating temperature.)
• Be sure to use this unit within the allowable ambient temperature range (5° to 40°C) and humidity range (80% or less).
When you use the unit out of this temperature range, the internal parts may be adversely affected or a malfunction may
occur. In addition, when the temperature rises high, the characteristics of the HDD may deteriorate or its lifetime may
be shortened. When you use the unit in a low temperature environment, supply it with power for at least 10 minutes
before use.

Notes for constructing a surveillance system using this unit
• This unit can be controlled by external devices via the external connector, RS-232C connector, or LAN connector. In
addition, external devices can be controlled via the external connector, RS422/485 connector, or RS-232C connector.
These functions allow this unit to flexibly support an advanced security system. However, depending on the settings
of this unit or connection or combination with external devices, this unit or externally connected devices may operate
wrongly, causing adverse effects on the entire surveillance system.
• When constructing a surveillance system using this unit, you are recommended to check its operation by connecting or
combining it with other devices in advance.
• Don't use the alarm function of this unit for the purpose of making serious decisions or for applications involving human
lives.
• When this unit becomes unable to recognize an external device in recording because of a power failure, voltage drop,
or other failure, the recording point may move to the HDD inside this unit or other HDD. To prevent such symptom, it is
recommended to use an uninterrupted power supply or other similar device.
• When you unplug the power cord or turn off the breaker during recording, the HDD may be broken or recorded data
may become unable to be played back. When you turn on and off the breaker every day, program the timer recording
to be performed while the breaker is on and don't turn off the breaker during recording.
• When the user or any third party uses external devices wrongly, or external devices are affected by electric noise or
they are damaged or repaired, the saved data may be lost. Mitsubishi doesn't take any responsibility for damages
related to such data loss.
• By connecting external HDDs to this unit, you can expand the memory or use them as a copy device. However, when
you perform recording, playback, or copy at a high rate using this unit, recording or playback data dropout or other
failure may occur depending on the connected device because of slow data transfer or slow response. Be sure to
check for such failure before starting the practical operation of the unit.
• Don't use the function to control the powers of external devices using the bus power of this unit.
• External devices you want to use may not be suitable for the intended application of this unit. For details, you are
recommended to contact your Mitsubishi dealer.
