Aaron, first off I'm sorry to hear this BS that you and the family are going thru.... Second, they sell mock cameras that have a red LED blinking on top of them too give them a sense of being legit.... I mounted 5 of them around the garage and house on my last deployment and you'd be surprised at the number of people who made comments too my neighbors about them....
Made some of them down right paranoid..... They did the trick, the wife felt better, I felt better why being gone and at 15 a pop I saved a ton of money as well.... Win, win.....
I know you have the little ones, but as Rick asked does the wife carry? Or would she if trained???
