SINGLE-CHANNEL DIGITAL VIDEO RECORDER FUNCTIONS

■

Pre- and Post-Alarm recording

Since the C-DR0101/C-DR0100/C-DR0105 are all digital units, they are able to offer advantages that analog systems cannot such as the pre-alarm feature which allows setting a time in eight increments from 0 second to 5 minutes. If an alarm is generated, the unit has already been recording from the preset time period. This makes sure nothing is missed when viewing footage from the alarm. A post-alarm function with similar time increments is also provided.

The C-DR0100 incorporates a 120GB HDD while the C-DR0101 is equipped with 240GB (2 X 120GB) HDDs and C-DR0105 is equipped with 500GB (2 X 250GB) HDDs. Large capacity hard disk drives such as these make it easy to achieve extended recording times for effective monitoring.The use of large hard disk drives eliminates having to change tapes and perform periodical maintenance as such tasks are essential when using

conventional time-lapse VCRs. In addition, only digital recording can offer such high picture quality, extended recording periods and effective high-speed searching.In order to achieve the most extended recording times while maintaining picture and audio quality for recording and playback, digital compression is utilized. Motion JPEG compression is employed for pictures of 720 x 240 pixel resolution.

500GB storage with 2 250GB HDDs built-in

■

(C-DR0105)

An immense storage capacity of 500GB is provided in the C-DR0105 that features two 250GB disk drives built-in. This allows recording over many hours, raising overall system effectiveness and significantly adding to ease of use for monitoring applications. If less recording capacity is desired, the C-DR0101 equipped with two 120GB disk drives built-in and the C-DR0100 equipped with a single120GB hard drive can be used.

■

High picture quality

Advanced digital compression technology provides picture quality with a resolution that exceeds 400 lines. Full digital operation means picture quality with clarity that easily surpasses S-VHS. Since all video is recorded directly to the HDD, there is no picture deterioration even with repeated playback.

■

Versatile recording with a choice of three

■

modes:

general recording, internal timer recording and

alarm recording.

• Picture quality from a choice of levels and recording interval from can be set independently in each mode.

• Picture quality can be selected from 5 different file sizes ranging from a standard picture quality file size of 16KB to a high picture quality file size of 64KB.

• Internal timer recording allows setting up to 10 different timer programs.

• Alarm recording offers two different alarm input modes, each allowing different items to be set to suit different monitoring requirements.

Comprehensive high-speed search functions

Because the hard disks can store a significant amount of recorded data, it is important that sophisticated search functions provided:

Time Search

Inputting the date and time desired activates searching by date/time. Once a value is input, the frame starting at the time selected will be displayed. This makes it easy to search forward and backward from that point.

Block Search

Selecting a block* of dates/times performs searching by block. Once a block is selected, it will playback repeatedly.

Time Shift Search

Increasing or decreasing the amounts of time as desired from a designated time activates searching by time shift. The frame at the designated time will be displayed, facilitating searching.

DIGITAL VIDEO RECORDERS & MULTIPLEXERS

DIGITAL VIDEO RECORDING

Multi-Channel Digital Video Recording System

Cost-effective and high-performance digital video recorder systems to meet a user's specific requirements can be assembled. A maximum 16 channel recording system can be flexibly configured by combining a C-DR0105/C-DR0101/ C-DR0100 single-channel recorder with a TOA multiplexer such as the C-MS91D and C-MS161D model by utilizing the RS-232C interface to link the units. Such a system comprising TOA digital video recorders and multiplexers offer significant system advantages such as automatic mode switching by the multiplexer on playback and automatic time synchronization between the digital video recorder and multiplexer.

9-Channel Digital Video Recording System

The full screen is divided into 192 frames (16 horizontal x 12 vertical) which do not appear on the screen. Size of the object for detected can be set by selecting horizontal and vertical frames and inputting these values.

Motion Detection Area setting

The full screen is divided into 16 areas (4 horizontal x 4 vertical) and motion detection can be set to activate in any of the 16 areas.

For example, when wishing to eliminate constantly moving portions such as trees swayed by wind from the motion detection area, set the corresponding area to OFF(- -).

Sensitivity Setting

To minimize detection errors, five levels of sensitivity settings are provided to allow fine adjustment control.

The multiplexer detect the change of brightness in the area that is larger than the set object size in the activated areas.

Alarm Recording

The number of recording frames for the camera that detected motion can be set to increase.

For example, when wishing to detect a person but not wishing to detect a dog, set the object size to be larger than the dog and smaller than a person. If the object size is set for 2 horizontal x 5 vertical frames, such as in the figure at right, a person's motion can be detected, but motion of the dog will not be detected.

Maximum 1,000GB recording time possible.

To gain the very maximum recording time possible, two TOA C-DR0105 digital video recorders can be set up for serial recording in conjunction with a TOA multiplexer. Connected in this manner, a digital recorder will signal the second digital video recorder when its hard disk drive is full, automatically starting the second recorder so nothing will be missed. .

When first digital video recorder storage is full, the second unit will start to record.

When the second digital recorder storage is full, recording starts again on the first unit by recording over what was previously recorded.

Versatile Alarm Functions

TOA multiplexers offer many alarm functions that are easily set in the setup menu.

Sensor Alarm: Each camera connected is equipped with a sensor input terminal. Alarm activation triggers a buzzer while onscreen display warning and video recording speed is automatically set to standard speed. Multiple Alarm Inputs allow prioritizing cameras when an alarm is generated. When multiple alarms are generated, video image switching is suspended and the alarms are put on hold so that the operator can select the alarm’s corresponding camera’s images to view in desired order. In addition, each alarm terminal can be set to notify on a break-or-make or make basis.

Digital Video Recorder Reproduction Alarm: A buzzer sounds when playing back the part of a recording that contains a sensor alarm event.

Video Loss Alarm: Alerts when power or signal from a particular camera is lost. Letters "VL" and the camera ID number will be displayed.

Alarm Information: Dates, times and camera ID number of sensor and video loss alarms can be reviewed on an independent alarm information screen. A maximum of 64 events will be recorded and a new event will record over the oldest event.

Multi-Language Ability

Offering flexible use for multi-language environments, TOA multiplexers will show onscreen information and allow menudriven set-up and operation in English, French, and Spanish.

Summer Time (daylight savings)

The timer function can be adjusted for summer time and can also be set to adjust automatically for it.

Key-lock function

A key-lock function can be set to prevent unauthorized access to unit controls and tampering.

Remote control

Each multiplexer is equipped with an RS-232C port on the rear panel so that it can be linked for control externally from a remote location. The C-RM500 Remote Controller can be used to switch and select cameras individually or by group, sequence-display, multi-split screen modes. It connects to the multiplexer via the remote control terminal on the rear panel.

Frame Recording Function

The frame recording system switches cameras for each frame while recording. For every frame, a multiplexer sends a different picture taken by a different camera to a Digital Video Recorder so that a single Digital Video Recorder is able to make recordings for multiple cameras. Continuous images can be reproduced during replay by reading corresponding frames for each camera. Recorded images may be viewed as full-screen display for each

independent camera or in a split-screen display that shows multiple camera views at the same time. A conventional sequential switcher changes camera feeds every few seconds,making continuous motion replay impossible. Allocating a Digital Video Recorder for each camera is also prohibitive in terms of costs. Multiplexers that use the frame recording system records images from all cameras and are cost-effective.
