Window Alarm Sensor

No content

Best Buy customers often prefer the following products when searching for Window Alarm Sensor.

You've heard it before: Burglars can sneak into your home through a window that's left open an inch or two. If you're worried about this, consider installing a window alarm sensor, which triggers an alarm if the window is opened and there's no one at home to hear it. The sensors are easy to install and work with any type of window, and they're sensitive enough to detect a slight breeze.
