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.

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.
