I don't have numbers, but I don't think there is much home burglary as a crime of opportunity in Switzerland. The places worth entering, usually have good enough security measures, that you need to come prepared and it is going to take you some time. What you usually hear is certain neighboorhoods being scouted for lights being off for longer time, indicating the people are on vaccation. But I don't know in what regards crime predictions systems are useful for that, what value they add.
