Interesting question! The most important factor is to not make it EASY for anyone to break in. That means keeping shrubbery away from windows, having your home well lit, keeping it secured with good locks and making it appear 'unpredictably occupied'.
I just had a client show me a 'device' she bought through the Airmall catalogue (the one you get on airline flights). It was a motion detector (that detects motion through closed blinds even...) It sounded like a large german shepherd barking when someone walked near the front of the house. After a break in they'd bought this item that they turn on when they leave the house. Their postman is convinced that they really have a dog after two years, and thinks that it doesn't bark when they're home.... they haven't had a problem since!
