Intrusion alarm system - experiences?

The worst thing each time is the property damage and loss of earnings. I wanted to install a fogging system, very effective! But the installation company doesn't want to because the smoke detectors would then go off. I say, it doesn't matter then, maybe even good. But they won't do it .....

here are some pictures of the EMA installed in a school once again. Sorry, only managed to do it today.

Cool and thanks!!! I will discuss it right away over the weekend. Have a great weekend!

Oh, the doors are also additionally secured with magnetic contacts

Hello just out of curiosity, have you already decided on a system?

It turned out to be a Honeywell with 24-hour emergency service. It was ultimately the insurance requirement. But it works for now.
