4. GENERAL DESCRIPTION
TOA's C-DR Series Digital Video Recorders feature a digital compression method that permits camera images
to be recorded on an internal hard disk. The C-DR091 Series is designed for 9 channels, while the C-DR161
Series can be used for up to 16 channels.
It can simultaneously play back recorded camera images while continuing to record images onto the hard
disk.
Mounting in EIA-Standard equipment racks can also be easily performed with the addition of optional rack
mounting brackets.
6. FEATURES
• Simultaneous Recording/Playback Function
Recorded images can be played back without interrupting recording.
• Triplex (Rec Pl Live Image) Function
Live and recorded images can be simultaneously viewed during recording in multi-screen display.
• Pre-Recording
Retroactive recordings can be made for up to 5 minutes before the occurrence of an alarm event (alarm
signal input or motion movement) or priority recording, even if no recording is currently in progress.
• Speed Search Function
Date/time Search and Event Search functions permit desired scenes to be quickly found and viewed.
• Mirroring Recording
Mirroring Recording function performs 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.
• High Picture Quality and High Frame Rate
Recording and playback can be simultaneously performed at a maximum of 100 IPS. (Image compression
method: Motion-JPEG.) Picture quality can be adjusted in five levels, allowing high quality recording or
extended recording according to the intended purpose of use. Picture quality and recording intervals can be
freely set for individual cameras and recording system.
• Auto-recording
The Digital Video Recorder starts recording shortly after power on and makes recordings by preset
schedule. The auto-recording function permits Normal recording and Alarm event recording, for each of
which different setting can be performed. (Refer to
p. 79
