AXIS M5065 PTZ Network CameraAbout applicationsAbout AXIS Audio Volume DetectionAXIS Audio Volume Detection is an application that triggers an event if the audio volume rises above or falls below the set volumereference level for a specified time period. The generated event can be used, for example, to record a video or alert security staff.ConsiderationsBefore using the application, consider the following:• To avoid false triggers, try different gain and threshold settings to optimize the performance for your environment.• Adjust the audio input gain to a level where the background noise covers approximately 30-50% of the application’s audiolevel graph. To access the Input gain setting, click the Audio Settings link on the application page.How to set the detection threshold and durationNoteTo disable detection during PTZ operation, select Detection automatically disabled during PTZ movement.1. To set the detection threshold to a level where the gray line is just above the background noise level, enter a valueor move the slider for Threshold.2. To set the time required for the audio volume to be above the detection threshold before the trigger is activated, enter avalue or move the slider for Above Threshold (s).3. To set the time required for the audio volume to be below the detection threshold before the trigger is deactivated,enter a value or move the slider for Below Threshold (s).4. Click Save.An active trigger is indicated by a red color bar in the trigger status area. For more information on how to setup an event for thetrigger, see How to set up action rules on page 34.About AXIS Scream DetectionAXIS Scream Detection is an application that triggers an event if a scream is detected. The generated event can be used, forexample, to record a video or alert security staff.An active trigger is indicated by a red color marker in the trigger status area. For more information on how to setup an event for thetrigger, see How to set up action rules on page 34.ConsiderationsBefore using the application, consider the following:• The application is mainly intended for detecting screams in a generally quiet environment. The difference between thebackground sound level and the scream must be at least 15-20 dB for the application to function effectively. Considerthe proximity to the expected sound source, the background noise level and the audio input gain level when installingthe product.• Adjust the audio input gain to a level where the background noise covers approximately 30-50% of the application’s audiolevel graph. To access the Input gain setting, click the Audio Settings link on the application page.• If the interval between screams is less than 3 seconds, the application regards it as one scream.About AXIS Removed Object DetectionAXIS Removed Object Detection is an application that triggers an event if an object in a set area is removed. The generated event canbe used, for example, to record a video or alert security staff.31
