The audio level detection filter allows you to search for event logs triggered when cameras recognize that the audio level is too high or too low.
To add the filter, click on Manage Filters, then click on the Audio Level Detection tab.
To activate the filter, simply click on the checkbox to the right of the filter.
You can select the devices you want to filter, as well as the type of detection event, either High Level or Low Level. Select the items you want by dragging from the left list to the right list.
