Built-in 9-input multiplexer functions
With the number of operational cameras increasing, the combination of unit and multiplexer has become standard.
In our pursuit of the high-quality image playback characteristic of digital recording and a way to make the recording
operation more ideal, we have included a versatile multiplexer capability in this unit.
• Camera switching and split-screen display
Throughout terminals for non-simultaneous connection of 9 cameras. Split-screen modes of Single screen, SPLIT
4, or SPLIT 9 screens for sequential display.
• Timer Program link function
Registration of 3 kinds of camera recording operation patterns.
User-specifiable alteration, through use of the timer recording program, of the number of operational cameras by
schedule.
• Electronic display enlargement function
Electronic display enlargement of user-selected areas within the currently displayed image. For example, display
enlargement of the cash payment counter using the main unit’s controls.
Unit with built-in, large-volume hard disk drive
This unit realizes high-resolution playback of over 400 horizontal lines thanks to digital technology using JPEG
compression. There are 5 user-selectable image quality settings. The main device also features a built-in, large-
volume 30GB hard disk for both high reliability and high-speed operation. Users can select from 12 recording
intervals ranging from 25 frames-per-second to one frame per 8 seconds, and up to a maximum 2,197,000
frames can be recorded consecutively.
Non-stop recording capabilities and recording media
To handle applications requiring long-term storage of recorded images, this unit is capable of using supplementary
devices to create backups and copies without interrupting hard disk recording. Used in conjunction with the wide
selection of media, this unit can handle many different kinds of non-stop recording.
• ARCHIVE media
Backup capability using the recording devices available on the market – such as DDS, DVD-RAM, and MO – as its
supplementary peripheral recording device.
• Backup while recording
Backup and copying operations without interrupting the non-stop recording operation.
Convenient maintenance by using the Timer Program to designate the time of simultaneous backup operation; for
example, to create a complete backup on a given day of every week.
• Peripheral hard disk expansion
With 9-camera input capability, up to 3 peripheral hard disk drives (max. 132GB) can be added to supplement the
built-in hard disk when extended recording time is needed.
User-friendly operation
Because of the internal structural differences between standard Unit and time-lapse VCRs, there has been a
weakness in the area of intuitive operability. With consideration to this point, a control panel featuring the same
control key layout of time-lapse VCRs and a JOG /SHUTTLE have been used for this unit.
Versatile functions to support surveillance
• Audio recording function
1-channel PCM audio recording mode included. Along with clear surveillance images, clear audio quality of cash
register operation, customer conversations, etc.
• Image-alteration recognition function
Processing of each image recorded with this unit using a proprietary image-alteration recognition method.
• Versatile high-speed search operation
Easy searching using a proprietary searching algorithm. Options include searches through alarm input-time list,
designated days, skip/index searching, etc.
• Excellent expandability
Standard inclusion of RS-232C interface for remote PC control, and various control terminals. Flexible use even for
high-level security systems.
• Pre-alarm Recording function
Recording of images recorded before the alarm sensor detects disturbances. Enhanced surveillance effect through
the capture of the decisive moment before the alarm.
• 4-character year display
In consideration of the Y2K problem, a time-date generator using four characters for the year display is included.
