The VideoJet 8008 uses a special recording mode for alarm recording to

optimize the use of the memory capacity. As soon as a time slot for alarm

recording begins, continuous recording starts on a segment the size of a

complete alarm sequence (pre- and post-alarm).

This segment on the partition works like a ring buffer and is overwritten again

and again until an alarm is actually triggered. After that, recording on this

segment will go on for the time predefined for post-alarm recording, and then a

new segment will be used in the same way.

For this reason the recorded alarm file is always saved at its full length to the

partition and the recording space required for each alarm recording can be

calculated easily.

Number of alarm tracks:

Here you set the number of alarm tracks on the partition. One alarm event can

be recorded on each alarm track. The specified number of alarms can be

recorded and archived accordingly. A partition can contain a maximum of

128 alarm recordings.

If the Ring mode option is set for the partition (see page 82), the predefined

number of the latest alarm recordings will be stored. If the Linear mode option

is set, recording will stop as soon as all the alarm tracks have been written.

Pre-alarm duration:

Select the period to be covered by the pre-alarm recording.

Alarm recording duration:

Select the duration of the alarm recording.
