Audio Detection with the Admiral and Imperial NVRs

Audio Detection Modes

Sudden Rises: An alarm is reported when the rise of volume exceeds the difference.

Sudden Fall: An alarm is reported when the fall of volume exceeds the difference.

Sudden Change: An alarm is reported when the rise or fall of volume exceeds the difference.

Threshold: An alarm is reported when the volume exceeds a threshold.

Threshold: After a volume is set as the threshold, an alarm is reported when the threshold is exceeded.

Difference: the difference between two volumes. When the rise or fall of volume exceeds the difference, an alarm is reported.

Note:The scale in the audio detection area is used to measure sound volume.

Audio detection results are shown in real time. The red part indicates that the volume of the audio alarm has reached the threshold and the alarm does not necessarily reports.

Audio Detection is available on these NVRs when combined with SCW Admiral Line Cameras with Audio Inputs or Microphones:
