I talked to the alarm guy today would you be surprised to hear that they are very busy?
Some points of interest.
He said that about 80% of break ins come through a door.
A conventional door is childs play to get through

and it wouldn't necessarily make much noise.
The guy I talked to didn't like outside equipment which he thought gives too many false alarms and breaks down in the elements and is subject to tampering by bad guys

I had thought the ideal thing would be to catch bad guys while they were in the yard.
He was doubtful of the value of outside lighting.
I guess I wasn't too surprised to learn that the existing system is totally obsolete and would need to be replaced except possibly the wires.
He didn't think too much of surveillance cameras but of course he would be happy to install them if thats what I really want.
He also thought there was too great a chance of most people shooting somebody they didn't intend to so he wasn't a big fan of guns.
Looks like everybody has their own ideas about how to best defend the home.
