Why Window Sensors Are Critical for Home Security
Most break-ins happen through windows — not doors. Smart sensors provide early warnings, trigger sirens or routines, and give you peace of mind even when you’re not home. Some models even double as temperature or humidity sensors.
What to Consider When Buying
Look for easy setup (no hub required), good battery life (6+ months), reliable app alerts, tamper protection, and integration with your existing smart ecosystem.
