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.

Arlo - Home Security System with Wired Keypad Sensor Hub, (5) 8-in-1 Sensors, and Yard Sign - White
Model: SS1501-100NASSKU: 6517937Top comment"UNBOXING & INSTALL: - As seen in the picture, this unboxing is straight forward which I like. the keypad is nice and low profile and I love the look of the sensors. - Overall the install was very easy. You plug in the sensor hub first, and once that is setup via your Arlo Home app, it’s very easy to connect the remaining sensors. - The sensors go on with a sticky pad which makes it easy to go on any surface and also makes them removable if you ever move or want to place the sensors somewhere else. - Let me also add, you are not required to have a subscription to use this alarm system. ...Such a huge upgrade from my old alarm. What my husband liked the most is that he didn't have to install so many pieces compared to other security alarms we looked at, and it gave us lot more detection options."
