Alarm triggered Notification to sound like an Amber Alert

the ability of the app to bypass the phone volume and set off a loud alarm when triggered. Similar to an amber alert.My alarm was triggered when I was out shopping and all my phone did was a light vibration and make a soft chirp. That is not enough indication that my alarm is going off. I had no idea what the sound was. Until i looked at my phone and look through my notifications and reviewed my cameras and had to deactivate before the police was notified.
