Is there a way to activate an audio notification to play on speakers when an object (i.e. package) or person (i.e. mail carrier / delivery driver) enters a configured box (IVS-like) in Blue Iris? I've played around with the audio notification settings in the main display area, but it doesn't seem to trigger any sound even with motion detection enabled (the motion detection markers are still visible though during playback), even though I have the output set to my speakers. I've been relying on PIR Motion Detectors, but the sensitivity varies especially when I have creatures (small, medium, and large), crossing paths of the PIR. I'd rather rather try digital detection instead seeing that Blue Iris purportedly triggers less false results and better motion detection overall. Thanks
