We have a security system that calls the cops if anyone tries to break in. You need a password to get in or the monitoring call center calls your cops right away.. I thought it would really be expensive but its not. its called Simplisafe abd costs $25 a month for them to monitor it (and you dont have to take the monitor and can do it yourself, but the monitor will call the cops if anyone is there). Cost us about $200 up front but I feel very safe and just being able to see your house on it tje makesphone is easy to miss an intruder. We also have that. And we have motion lights all over the house. Lights up like sunshine if anyone passes a sensor even at midnight. Detours would be dope robbers. Depends on how hard you want to keep people out. Our town has almost no murders but lots of drug use and as we all know drug addicts, even high school kids, break in to homes that are vulnerable. So we decided to play it safe. But anything beats nothing and DO call the cops if anyone breaks in your house, even a loved one! No one has the right ti break into your house. It is especially horrific and a betrayal if it is one's beloved child. I am so sorry for your angst.
