I would like raising alarm, meaning the alarm will go louder and for longer time when more and more persons are detected.

For example a person triggers default 5 seconds alarm.

When second person is detected within one minute, alarm will go louder for 15 seconds.

Third person and more within next minute, will trigger loudest alarm for 30 seconds.

After 10 minutes alarm would reset to 5 seconds, normal loudness.

Please add also alarm loudness control to smart actions.
