I always thought glass break sensors were a waste of money for residential jobs

For years I skipped them, figuring motion detectors and door contacts were enough. Then I did a job for a friend in a quiet part of town where they had a big glass sliding door facing the woods. I finally agreed to add one just to be safe. Two months later, a rock thrown from the woods set it off before anyone even touched the door, and the cops got there fast. It completely changed my view on layering protection. What's the most reliable brand you guys have found for those sensors in humid areas?

Ever have a problem with false alarms from those things? I've seen them go off from loud thunder or even a big truck rumbling by. In my area, the humidity messes with the adhesive over time, so they just stop working right. I still think good motion sensors and reinforced glass are a better use of the money.

Switched to dual-tech sensors and haven't had a false alarm since.
