Enable pre-trigger and/or Post-trigger recording - The AXIS 250S MPEG-2 Video Server is
capable of recording directly before and/or after an event occurs. This is achieved by constantly
buffering (and overwriting) a certain amount of the video stream into the internal memory.
When the event is triggered, the memory contents are added to the actual recording.
