I have a system , wireless door sensors on all main floor doors, water leak sensor in laundry room , motion sensors in the 2 garages, and a camera on the main floor that takes 5 photos when the front door is opened and a 5 min video when an alarm is tripped that gets sent to my smartphone instantly. It pays for itself with the insurance discount. It also lets me keep tabs in my wife .
I haven't had a false alarm yet and if Alarm is tripped the monitoring company calls me , and my wife before sending authorities .
But this guy is my best deterrent
