What specific security system are you using with PIR?
One cheap and simple option is perhaps the Yonomi App with one of the compatible sensors.. without the need for a smart-hub, but you may need a device at the premises with the app running in the background… at least it used to require that but it’s been a while since I have used it.

This will be a completely new system, so I can purchase a new Smart Hub / PIR / laser beam etc
I plan to use the Smart Hub to integrate with Shelly lights as well.
With SmartThings, you can create an automation in the app for a triggered motion sensor to play music at a specific volume out of a specific Sonos speaker. Although it doesn’t seem to allow you to choose a specific track. If you want the “dog barking” track to play, you would have to set it as the current song in the queue on that speaker.

I have a Hubitat hub and am very pleased. :) I have various rules that range from speaking a warning that their image is no stored in the cloud, from playing music, to a warning siren. All straight forward and unlike Alexa, it also has the ability to backup all of your rules etc.
It also has the advantage that it runs locally, rather than in the cloud.
