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.

    "Also, it seems as if the outdoor sensor is not accurate as compared to an old hanging thermometer and Apple Weather. ...We have many AcuRite products and we love them; with the exception of the dual alarm clock - the one we purchased originally was replaced under warranty and eventually that one died so we purchased another only to have that one die as well (outside of the warranty period, of course).

    "Initially, the light was very bright, but I turned it down and it's fine. I haven't used the alarm yet and the forecast is still in learning mode. ...Put a hinge where the bottom and back one together so it can be folded for easy traveling. The alarm feature is of little value for me; I set the alarm on the phone and use your device to charge the phone. "
