When I first moved to this house in 2009 I had trouble at night with knocks on my door & no one there & doorbell ringing & also them trying to get in my back door. So I bought just a cheap video camera from Radio Shack for about $75.00 & my Grandson installed it. We found out right away it was a neighborhood teenage boy messing around. I didn't involve the law but I had a talk with the kid. It never happened again & he now is 20 years old & comes down & does chores for me when I need anything done.
