Well my motivation started when I found an uncoiled coat hanger on top of my car. So I bought two cameras (both with IR illumination) and pointed them to the two sides of my car. Even a casual observer will notice the two cameras (with 2 rings of glowing red lights) pointed at them when they enter my driveway. I figure it's a $120 worth of prevention... hopefully. The cameras can read the license numbers of cars going up and down my dead end street, and have a NTP synced time stamp on them. So I have reported license plate numbers to the police a few times when various neighborhood issues have come up. But no, I don't think it will magically arrest someone breaking into my house. But they are still pretty useful. Did someone leave a package on my front door? Is my kids friend's parent here for pickup/drop off? Did the garbage truck get here yet? WTF is that loud truck noise out front? Is that knock at the door someone with a clip board? Or someone trying to get me to believe in their god? One thing it does help, is that at least in my area it's common for a thief to knock to see if anyone is home, then break down that door or force a rear door to enter the house is nobody answers. So being able to see and even respond to the knocker might well prevent a breakin, even if you aren't physically there.
