Alarm recording:
This is where you program the time spans where the alarm trig-
gered recordings will be active.
The VideoJet 1000 disposes of a special recording mode for alarm
recording to optimize storage capacity utilization: with the begin-
ning of a respective time slot continuous recording starts on a seg-
ment the size of a complete alarm sequence (pre- and post-alarm).
This segment on the partition works like a ring buffer and is over-
written 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 complete in length
when saved to the hard drive and the recording space necessary
for each alarm recording can be calculated easily. A partition can
record up to 128 alarm activations; when the partition is in ring
mode it will always contain the most recent alarm recordings in the
predefined number.
Note
When the time slots for time recording and alarm recording overlap
each other the time recording schedule will always take priority.
Alarm activations that occurred during time recording are specially
marked on the playback bar for easy identification when playing
back recorded sequences.
Properties:
For a quick overview you have access to the properties of the active
partition directly from the recoding scheduler.
Recording activ:
This is a quick way to know if currently recording on the hard drive
is active. In this case the symbol for the hard drive is animated. If it
is not animated no recording is taking place.
