Glass break sensor mount and quantity recommendation

Here is the layout of the living / dining and master bedroom.

I'm no expert user, but after two years, its getting close. Lol 🤔

I sat a couple in the basement. What I'd try is the clap test they outline, see testing link below & at the bottom of that page.

I have since added Zigbee vibration sensors to my other DIY system, stuck to the center of some windows for my own testing purposes. It breaks or rattles enough, I'll know it. 🚨

So, one for each per room, position to cover the area you defined, do the clap test from each window area. Go from there as needed. Dining & living is a large room. Or just buy several, your call.

Be aware, because I'm old and don't remember, they have sensitivity settings, low, medium and high perhaps for adjustment. But high might be more sensitive to false alerts.

And also that anything similar to glass breaking sounds, shatter, thumps, etc on TV or in the dining room, dishwasher  etc., "might" set off the alarm if armed home for example in the evening.

They don't have to be stuck on, they can sit on something for better angle. Children or animals could readjust the angle though.

20 feet is the recommended max distance, but with heavy curtains, less, 5 or 10 perhaps. Closer may be better, requires some testing.

Thanks and greatly appreciated your recommendations!
