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 (Recording + Playback + 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. For models with a
single hard disk (versions with model number suffix -08, -1, D08 or D1), the mirror mode is available only
when the hard disk expansion unit is connected.
The possibility of data loss due to hard disk failure is greatly reduced, increasing reliability.
