I would love to know that too. Maybe someone has some experience in that field and will share his opinion. I am most interested in information about anti-burglary systems and fire protection systems. On the internet, you can find a lot of useful information, but it's hard to separate the truth from falsehood.
I've recently heard about Nest Protect [link removed]. It looks like a good system, but I have never tested it and have no comparison.
I am particularly concerned about how the application connected to the device works - whether it reacts on the fly, does not bog down with false alarms? Has someone good advice? I would be very grateful for any information.
