As soon as an alarm event is taken into processing, the alarm event recording is played back automatically one time, at 1X speed. Playback is launched either from the moment of the beginning of the alarm event, or from the moment corresponding to the position of the alarm event flag (only when the alarm event is initiated automatically—see Initiating an alarm in the system).
If the alarm event was initiated automatically, the visual element set for the detection tool which initiated the alarm event will be displayed in the Surveillance window: or a detection area or virtual tripwire, which triggers the detection tool when it is crossed. The object which caused the trigger will be outlined with a red frame.
