With the hardware integrated into SISTORE MX, it is possible to record video
sequences from different cameras when using network or IP cameras. Signals
which are fed into the recording system from outside are used to control the
operation of the SISTORE MX during this process.
The following recording modes are available:
Event-triggered recording
Long-time recording
All configured cameras operate initially in long-time recording mode and supply live
images. Time settings and events assigned to the respective cameras determine
whether the cameras are recorded or not.
Long-time recording is a recording mode where videos are saved on the hard disk
until this is completely full. After that, the oldest pictures will be overwritten
continuously (time lapse mode).
There are two possible modes of event-triggered recording:
without pre-alarm history
with pre-alarm history
Recording without pre-alarm history means that the recording is triggered either via
an alarm contact, through motion detection, or via the software interface.
Recording with pre-alarm history means that the camera must already be
recording. If no alarm occurs, the recording (pre-trigger time) is overwritten after a
preset period of time. If an alarm is triggered - either through an alarm contact,
motion detection or the software control -, the post-alarm time is recorded
automatically. When this preset period of time has expired, the pre-alarm and post-
alarm sequences are saved and a new pre-alarm recording is started.
It is possible to activate a write protection for event-triggered recording.
NOTE
Please note that pre-alarm images will be saved permanently only after an alarm is triggered. If no
alarm is triggered, then the pre-alarm images will not be saved permanently. An alarm may be
triggered either by an event (e.g. motion detection) or by an operator, for instance when pressing the
alarm button during or after a bank robbery.
