These are the latest in a series of alleged crimes caught on camera. Intruders crossing the threshold in to the place where we are supposed to feel safe, our own homes. In San Jose, California, this homeowner watched on multiple home security cameras as an intruder broke in to her home. Even pulling on the door to her bedroom where she was hiding. In central Florida, men dressed as ninjas breaking in to this home, tying up the homeowner. There are an estimated 1.2 million break ins every year. A home burglary happening every 16 seconds in the U.S. High-tech security cameras and alarms are little match for a trained criminal.

Reporter: Once he is sure it is empty. Walk back here. Perfect. An unlocked window is invitation. I'm in. I'm going to make sure the doors are unlocked in case I need to get out of here quickly. He said this homeowner, like so many of us makes it a snap. It doesn't matter race, nationality, income bracket, age, almost every single person puts things in the same place as the next one. Up to the master bedroom. First place I like to check. Common knowledge to all burglars, master bedroom first. That's where the jewelry's at. That's what a burglar is looking for. When I opened her top drawer it was filled with jewelry bags and box. They group it together. It is matter of organization or ease for them. If it is easy for you, it's easy for me. Crime knows no boundaries, no demographic. No such thing as a safe neighborhood. You never know who's casing your neighborhood. Now a security expert, Kathleen Baty was once the victim. A man tried to kidnap her from her own home. I came home from work and was listening to my answering machine and he was in my home behind me with a knife. Reporter: Her attacker went to prison. From that day she never let her guard down. I lived the rest of my life in wait for it to happen again. Reporter: She wants others to be vigilant, too. Baty says many houses that appear safe are vulnerable. Houses like louisas. He can't get in. I'm sure of it. Something I saw for myself when I spent the day with another convicted criminal. He told us he is reformed and wants to help people protect their homes. The window's open. Reporter: First point of entry the car in the driveway with windows down. Bingo. The garage door opener in plain sight. Within 45 seconds he's in the garage and finds the door to the house unlocked.

You thought maybe it has a garage door opener in it. Keys, garage door opener. They will leave -- they won't think about it in a hurry to get in the house. Just leave it all sitting there.

First Baty says never leave your garage door opener in plain sight. They are watching and waiting if that are moment. Don't make it easy. Reporter: Better yet, lock the garage. You want to disengage the motor of your garage door opener and manually shut your garage door and bolt it. So no one can open it from the outside. Reporter: It turns out 73% of home break-ins are by kicking in a door. Baty says there is an easy solution for that too. You want to install a strike plate, a metal plate that goes all the way down and makes it more difficult. In other words you don't want the door to break apart. Exactly.
