Event triggered recording
50,000 events can be stored for each camera. Each event consists of an alarm
image and the pre- and post-alarm sequences.

For event triggered recording, recording is controlled by the corresponding
control input and/or integrated motion detection. Event triggered recording
creates a separate entry in the image database for each event, as opposed to
continuous recording. Later evaluation uses camera selective display. For
event triggered recording, recording speed and recording duration can be
specified separately for pre- and post-alarm sequences.
Event triggered recording has two advantages over continuous recording:
■
Event triggered recording with defined pre- and post-alarm sequences
allows for a more precise evaluation of images based on event selection.
The alarm image and events before and after the alarm can be analysed
directly.
■
Event triggered recording, as a rule, only records relevant data. Evaluation
is therefore to the point and much faster.
