When multiple alarms are triggered the annotated cameras display snapshot, pre-alarm recording and live video stream on the alarm monitor in individual rows based on the selected layout, for example 4x4. The video footage (that is snapshot, pre-alarm recording and live video stream) of the most recent alarm is displayed on the first row and previous alarms in the rows down below. For example, if four alarms are triggered simultaneously, the video footages of the alarms are displayed in the four rows of the alarm monitor in the order of alarm priority. For each alarm an incident is shown in the Incidents list.
When an operator selects an incident the related video footage is also displayed on his spot monitor.
When an operator acknowledges the incident, the snapshot, pre-alarm recording and live video stream moves from alarm monitor to spot monitor and the video footage of alarms on the alarm monitor is rearranged.
Example Scenario 1
Display of video footage of alarms on an alarm monitor with a 4x4 layout. If an alarm is acknowledged, it moves to spot monitor and alarms on the alarm monitor are rearranged.
No video footage on alarm monitor.
A new alarm comes in. Video footage for Alarm 1 is displayed on the first row.
Three more alarms come in. Video footage of Alarm 1 moves to the last row.
Operator acknowledges Alarm 2. Video footage of Alarm 2 moves to spot monitor.
Video footage of Alarm 1 moves one row above.
Example Scenario 2
If an alarm monitor is full and a new alarm comes in, the video footage in the last row moves out and remains in standby. The video footage of the new alarm moves to the first row and the rest of the video footage is rearranged. If an alarm is acknowledged, the video footage of the standby alarm moves back to the last row.
Alarm monitor is full.
A new alarm comes in. Video footage of Alarm 1 moves out. Video footage of Alarm 5 moves to the top row.
Rest of the video footage is rearranged.
Alarm 4 is acknowledged. Video footage is rearranged and video footage of Alarm 1 moves back to the last row.
