I agree that the more deterrents you can throw in their way, the better. As for my doors, no rope, no glass, automatic locks, video cameras and phone warnings should the door open without my knowledge. Garage door openers are getting smarter and smarter all the time, but then again, so are crooks!
Plus I turn on the car alarms and other security devices in my cars, even when they're parked in the garage. If they want MY stuff, they're going to have to WORK for it!
