Simultaneous Backup (Copying) method

In Simultaneous Backup (Copying), images input from the cameras are recorded once on the unit’s hard disk and simultaneously copied from the hard disk onto a removable archive/copying medium. Because images are first recorded onto the hard disk, the unit performs well for Alarm Recording and high-quality images needs, and can use “blank time” to backup/copy onto the separate medium. In addition, the unit marks the end of backup recording time through the use of the Archive Pointer.

Archive Pointer

The Archive Pointer is used to mark, on the archive medium, the completion of a backup process. For example, 100 hours of data recorded on the unit’s hard disk is to be transferred to a medium with only 80 hours of available recording space. When the backup process is com- pleted, the Archive Pointer will memorize the hard disk’s 80-hour mark. When the next backup process is initiated, backup will begin at this point.

SCSI Interface

The SCSI interface is the connection used expressly for transferring image data between the unit and its peripheral devices. Each peripheral is connected to the unit in a daisy-chain configuration, and is

given a unique ID number for detection/identification by the unit.

Relation of recording operation to the number of cameras and recording interval settings

The recording pattern of this unit is as illustrated in the diagram be- low. Image data input from all the connected cameras is recorded sequentially at a rate of [number of cameras x recording interval]. (Recording interval for each camera is 25F.)

For example, when four cameras are recording at intervals of 1 sec- ond, the unit takes four seconds to receive one cycle of image data from the cameras. When this data is played back on a single-screen, the display is refreshed once every four seconds.

Copying Device

The copying device is the peripheral device assigned to SCSI ID5. By using the unit’s COPY button, this device can be made to copy (re- store) image data recorded over a designated time frame.

Archive Device

Circuit recording interval per camera [ recording interval x # of cameras ]

1 second x 4 cameras = 4 seconds

The archive device is the peripheral device assigned to SCSI ID4, and performs the following: backup specification using the ARCHIVE button or Timer Program, and backing up of image data using the Restore function in the Copy settings.

Restore

Restore is the process in which image data transferred to the peripheral recording device is restored on the unit’s hard disk. During the Restore process, image data currently stored on the unit’s hard disk is completely over-written.
