For example, the audio content is “Hello”; the device is intsalled at the door. When people enter, it will say “Hello”; when people leaves, it will still say “Hello”.

Let’s suppose that here are two audio files in the device, one is “Hello”, the other is “Goodbye”. Then you can set: when people enter, it plays “Hello”; when people leave, it plays “Goodbye”.
