Perfect for small rooms, bedrooms and safes. - Simtek StealthALERT Wireless Alarm

I purchased this alert system originally for my vehicle when I have expensive or valuable items with me when I'm out and about. But Although zi do have a car alarm that isn't as sensitive as I would want it to be, I instead keep it in my bedroom around my firearm work area where zi store a lot of ammo and guns. It functions just as expected and is very alert and sensitive to intruders. I have tested out the various functions multiple times and it has delivered very accurate results each time. The are sent directly to your phone fast enough and the app is pretty easy to use. I recommend thoroughly testing out each function to get a feel for it. Motion detection, lighted from a dark room and vibration detections etc. I am happy with. It can definitely be placed anywhere you don't want someone to intrude.
