In my experience, they add an extra layer of protection by alerting me the moment a door or window is opened unexpectedly.
Types of Door and Window Sensors I Look For

Durability and Build Quality
I like sensors that feel sturdy and are made to last. Since they may be exposed to frequent opening and closing, I look for products with good build quality. If I plan to use them on outdoor-facing doors or windows, I also prefer models that can handle temperature changes better.
My Budget Considerations

I try to balance cost with reliability, features, and long-term use. For me, paying a little more for better performance is often the smarter choice.
