Since I work on the road, I have an alarm system. It's wireless my sheds/barn, and shop. All controlled from the house. All doors and windows have sensors on them. Then there are motion detectors set at 3 ft above the floors. i have timers I can set to allow how many seconds it takes before the sherriff and security people are called. And how many seconds before an ear screeching noise goes off. All of my phones are on the system too so when something happens, all the phones will cancel for a period of time selected, and the main system makes the calls to the authorities. Also have a panic alarm wireless and mechanical push button. It's all silent and the authorities are notified to come asap.
We only had 1 incodent. It involved a spider for 3 nights at 430 am. It was small enough to crawl inbetween the sensor contacts with it's catch and set the alarm off. Drove me nuts till I found it and removed it.
Each sensor is set to tell you verbally which door or window is open or not working
