This is something I have utilized in certain locations for at least 10 years. They are very effective. Don't ask me how I know.
https://www.burglarbomb.comI'd rather have my ADT. They won't get into my house undetected. I'd be afraid of those things going off accidentally. But they might work in some circumstances. Like an out building. And what if you have a fire and the firemen have to get in?
I have ADT, too, in my home. And, I never said they were to take the place of security systems. I'm speaking of outbuildings. As to the fire issues I'm so far away from fire teams (and the outbuildings are heart pine which burns exceedingly hot and fast), that I'm not too concerned for the firemen's safety. It'll be gone long before they get here.
