The Sound Detection feature allows you to determine what actions the recorder takes when there is an increase or decrease in the sound levels on a camera's audio.
Camera
Lists all compatible AI cameras on the recorder.
Enabling Sound Detection
To enable or disable Sound Detection for each camera just tick or untick the Switch check box.
Please note that Sound Detection will only be enabled whenever smart detection features are active as specified in the Smart Schedule.
Trigger When Sound Levels Increase
You can set the recorder to trigger when there is an increase in a camera's sound levels by setting the Rise drop down list to Enable.
You can then use the Rise Sensitivity field to set threshold for what the recorder determines as large enough increase in sound levels to produce a trigger. This can be handy in areas with regular background noise to prevent constant triggers.
1 is the lowest sensitivity level and will only trigger when there is a very loud noise.
100 is the highest sensitivity level and will trigger when there is a slight increase in sound levels.
Trigger When Sound Levels Decrease
You can set the recorder to trigger when there is a drop in a camera's sound levels by setting the Decline drop down list to Enable. This is especially useful in commercial and industrial settings as an alert if equipment or machinery stops working.
You can use the Decline Sensitivity field to set threshold for what the recorder determines as large enough drop in sound levels to produce a trigger. This can be handy in areas with ever changing background noise to prevent constant triggers.
1 is the lowest sensitivity level and will only trigger when there is a large drop in sound levels.
100 is the highest sensitivity level and will trigger when there is the slightest drop in sound levels.
Sound Intensity
The Sound Intensity is how loud the noise has to be for the recorder to monitor it. This allows you to account for constant background noise depending on the environment.
1 is the lowest sensitivity level so Sound Detection will only trigger when a loud noise increases or decreases.
100 is the highest sensitivity level so Sound Detection will trigger even when a quiet noise increases or decreases.
Setting Up A Sound Detection Schedule
You can setup an arming schedule for the sound detection of each camera individually as explained in the Sound Detection Schedule section.
