A True Doomsday Prepper
I finally put up my motion sensors yesterday. 800' wireless range, 4 zones, with 16 total sensors. Cheap, and they work great. I've used them for years. When something moves in a zone, the unit tells you which one. Get these now, if you can. You can buy additional sensors for under $25 a piece. Make sure you get a lot of 9v batteries too.
