What to Look For in Door and Window Sensors
Before you pick a set, think about how each sensor fits your home. Understanding how door and window sensors work helps you match the right type to your entry points.
Alert Type and Volume
Some sensors sound a chime. Others trigger a 90 dB or 120 dB siren. Louder alarms deter better. Chime modes help with daily routines.
Power Source and Battery Life
Most standalone models run on button or AAA batteries. Check whether batteries are included so you know the real cost.
Installation and Mounting
Double-sided tape is fastest for renters. Screw mounts are more secure for permanent setups. Placement matters, so review where to place door and window sensors before mounting.
Smart Home Compatibility
Zigbee sensors need a compatible hub. SimpliSafe sensors need a SimpliSafe system. Standalone alarms need nothing beyond batteries.
Monitoring and App Features
Some sensors only sound locally. Others send phone alerts or work with professional monitoring. Decide if you need remote alerts before you buy.
