For most people, a door contact sensor is the most popular choice as a sensor to guard your door and window, probably because it’s a handy choice as using for years and by many people. Is that a perfect choice? I am without doubt so far until I think about a shock vibrator.

I was asked by customers frequently for both door sensors and glass break detectors to guard their window? why? because the door contact sensor protects the window from being open and the glass break detector protects the window from being broken! Can you catch my thought?

Why don’t just install one shock vibrator on your window so one device protects your window from both case effectively? not only minimize the cost but also simplify your system!

Take one as a trial. You’ll like it.
