Considering that a lot of house robberies take place during the day when no one is home, hardening the perimeter is another option.
Clarification- you make the same mistake a lot of the media make.
Burglary-entering a building with the intent of committing a crime inside-building may be occupied or not.
Robbery-taking the property of another from them by force or threat of force. Someone comes into your home-sticks a gun in your face and takes your stuff-a home invastion robbery.
Theft-taking someones property without their permission.
Hope it helps.
