If decorative glass is part of your front entrance, don't let your alarm company install the control pad where I can see if it's set. That makes it too easy. And by the way; why would you pay all that money for a fancy alarm system and leave your house without setting it? A good security company alarms the window over the sink and the windows on the second floor, which often access the master bedroom - and your jewelry. It's not a bad idea to put motion detectors up there too. Even if you have and use your alarm avoid announcing your vacation on your Facebook page...It's easier than you think to look up your address.
