Archiving; Backup; Restore; Playback - American Dynamics Intellex Intellex DVMS Operating Instructions Manual

Chapter 1 — Introduction 9

Archiving

Archiving provides image backup, restore and playback on all
units equipped with a Digital Audio Tape (DAT) drive.
You can back up images in foreground or background mode.

Backup

In foreground mode, the unit stops recording until it finishes
backing up the database.
In background mode, the unit saves images to tape as it records.
Background mode is slower than foreground mode, but it does
not interfere with unit processing or the configured record rate.

Restore

You can copy up to 50 video segments from an archive tape to
the unit for review. Video segments contain images from each
camera recorded during the segment.

Playback

You can play back restored video at any time. Later you can
restore other video segments for review.

Alarm Processing

The Intellex unit provides one alarm input and one alarm out-
put for each camera, for a total of either eight or 16 (depend-
ing on model). You can select the polarity for each alarm in-
put.
The unit also performs a number of functions whenever an
alarm input is activated. It displays an on-screen alarm mes-
sage, permanently saves pre-alarm images to the image data-
base and activates the associated alarm output.
