3. FEATURES
High Picture Quality
Digital compression system ensures high-quality picture, audio recording, and playback.
Extended-Time Recording
Built-in 120 GB (C-DR0100), 240 GB (C-DR0101) and 500 GB (C-DR0105) large-capacity hard disks permit
extended-time recording.
Can Be Used In Conjunction With Switchers
Can be connected to TOA’s switcher system and used in place of analog time-lapse VCRs. In systems that
use a Multi-switcher (C-MS91D and C-MS161D), the Series Recording function that permits continuous
recording with the connection of two Digital Video Recorders can be enabled, and the switcher’s motion
detection function can be used as an alarm input to provide efficient surveillance by means of Alarm
Recording.
Simultaneous Recording/Playback
Recorded images can be played back without interrupting recording.
Pre-Alarm Recording
Pre-Alarm function performs retroactive recording to a maximum of 5 minutes before alarm activation.
Search Function
Three search functions Date/Time Search, Block Search, and Time Shift Search permit desired scenes to be
quickly found and viewed.
Mirroring Recording (C-DR0101, C-DR0105)
The C-DR0101 and C-DR0105 has two built-in hard disk drives. Mirroring refers to the simultaneous recording
of data onto the two hard disks. Even if one of the disks fails, recording and playback can still be performed
using the other disk. The possibility of data loss due to hard disk failure is greatly reduced, increasing
reliability.
Networking Function
An RS-232C interface and a 100BASE-TX Ethernet port are standard.
Note: The RS-232C control software is not standard.
6
Indicates a potentially hazardous situation which could result in
moderate or minor personal injury, and/or property damage if ignored
or mishandled.
CAUTION
When Using the Recorder
• Do not place heavy objects on the unit. Such object may fall or the unit may tip over, possibly resulting in
personal injury.
• Clean the unit periodically. Contact your TOA dealer regarding the cleaning. If dust is allowed to accumulate
in the unit over a long period of time, a fire may result.
• Clean the power supply plug and wall AC outlet periodically. If dust accumulates on them, a fire may result.
Insert the power supply plug into the AC outlet securely.
• Switch off the main power and unplug the power supply plug from the AC outlet for the safety purposes
when cleaning or leaving the unit unused for long periods of time. Doing otherwise could cause fire or
electric shock.
2. GENERAL DESCRIPTION
The TOA C-DR0100 (C-DR0101, C-DR0105) is a single-channel Digital Video Recorder with 1 channel of
video input, and permits connected camera images to be recorded onto its large-capacity internal hard disks
using a digital compression system. It can simultaneously play back recorded camera images while continuing
to record images onto the hard disk. The Digital Video Recorder can also be easily connected to an existing
switcher system, replacing previously installed analog time-lapse VCRs. Mounting in EIA-Standard equipment
racks can also be easily performed with the addition of optional rack mounting brackets.

4. HANDLING PRECAUTIONS
• Use the Digital Video Recorder in locations with ambient temperature of between +5°C and +40°C, and
humidity levels of less than 80% to ensure that no condensation is formed.
• When moving the Recorder, first switch off the main power and then wait at least 30 seconds before moving.
• Avoid moving the Recorder suddenly from a cold location to a warm location, or installing it in close proximity
to an air-conditioner outlet, as internal condensation could result. When condensation occurs, do not switch
on the power until the Recorder has sufficiently dried.
• Avoid installing the Recorder in humid or dusty locations, or in locations exposed to direct sunlight, sooty
smoke or steam. Note that even in locations which are not particularly dusty, dust may accumulate at the
Recorder’s ventilation slots. Because this could cause an extreme rise in temperature inside the Recorder,
be sure to clean the ventilation slots periodically after switching off the main power and disconnecting the
power supply cord from the AC outlet. It is highly recommended that the ventilation slots be cleaned once a
year.
• The socket-outlet shall be installed near the equipment and the plug (disconnecting device) shall be easily
accessible.
• To clean, be sure to first switch off the main power and then wipe with a dry cloth. If the Recorder is
particularly dirty, use a cloth damped in a neutral detergent. Never use benzene, thinner or chemically-
impregnated towels, which may damage the Recorder’s surface.
• Do not block the ventilation slots or cooling fan, which could cause the temperature inside the Recorder to
rise, possibly resulting in unit failure. Install the Recorder at least 100 mm away from the nearest wall
surface.
• Since the Recorder is equipped with a cooling fan, a motor sound is generated.
• Do not install the Recorder in locations influenced by strong electrical or magnetic fields, as monitor screen
pictures may become distorted or the Recorder could fail.
• Avoid jarring or striking the Recorder. The Recorder is a piece of precision equipment and accidentally
dropping it or subjecting it to strong impacts could cause its failure. When transporting the Recorder,
carefully pack it in the supplied carton to protect it from shock.
• Do not use the Recorder in locations exposed to vibration to avoid failure. Avoid installing the Recorder
vertically or tilting it at extreme angles, since it is designed to be used in a horizontal position only.
• About the hard disks
Hard disks other than those specified by TOA cannot be used. Since the hard disks are pieces of precision
equipment, take special care in handling not to accidentally drop, bump or jar them, lest they should fail.
If a hard disk on which condensation is formed is used, it could fail. Therefore, when brought into a warm
room from the cold outdoors, be sure to leave it unused for at least half a day before using it. If the hard disk
fails, recorded data cannot be restored.
• TOA takes no responsibility for any incidental damage, such as loss of sales opportunities, that may result
from the Digital Video Recorder’s failure.
• The standby function is used to enable transportation of the unit from one place to another when
circumstances do not permit its main power supply to be turned off. While in standby mode, power continues
to be supplied to the unit, but its hard disk and fan are stopped. If the unit is left in standby mode for long
periods of time, heat can build-up inside the unit, potentially shortening its operating life. To avoid this, be
sure to turn off the main power supply when the unit is not in use.
Underwriters Laboratories Inc. (UL) has not tested the performance or reliability of the security aspects
of this product. UL has only tested for fire, shock or casualties as outlined in UL's Standard(s) for
Safety. UL Certification does not cover the performance or reliability of the security hardware and

Note
• Avoid mixing both Normal Recordings and Mirroring Recordings on the hard disk. If mixed, block advance

the disk when changing the Disk Mode Setting. Note that all recording data are deleted when formatted.
(Refer to p. 26; "Disk Formatting.")
• Setting the Clock Setting’s Time Sync to "SLAVE" and the Recording Mode to "SERIES" places the
Recorder in Disk Full mode and causes the Disk Full indicator to light. Perform this setting when using the

• About Mirroring Recording. (C-DR0101, C-DR0105)
Setting the Disk Mode to "MIRRORING" permits the same recording to be performed simultaneously on the
two built-in hard disks. Should one of the two disks fail, the other disk will continue recording or playing back
to ensure automatic backup. Be sure to first format both disks before performing Mirroring Recording to
make their available recording times equal.
When a difference in available recording time between the two disk drives exists, recording can continue if
one of the two disks becomes full, provided recording time remains available on the other disk. However,
this will no longer be Mirroring Recording. The maximum available Mirroring Recording time can be checked
by setting the remaining time display to "MIN."

7.5.4. About the Alarm Input Mode
The Alarm Input mode for Alarm Recording can be set to "EDGE" or "LEVEL."
Each input mode operates as follows:
[Recording period when input mode is set to "EDGE"]
Performs continuous recording during Pre-alarm Recording and Alarm Recording Periods.
[Recording period when input mode is set to "LEVEL"]
Provides continuous recording during periods of time of Pre-alarm Recording, alarm activation, and Post-
alarm Recording.
Note
Pre-alarm recording is operated by the Alarm Recording Setting. It does not operate even if an alarm is
activated during General Recording or Internal Timer Recording since they are operated by their own settings.
