Why Door and Window Entry Alarms Matter More Than Ever
Our doors and windows are the most common points of entry—not just for us, but unfortunately, for intruders too. With break-ins often happening in under 10 minutes, the presence of a smart entry alert chime can be a powerful deterrent. For households with children, these alarms also act as silent guardians, alerting you when kids open a door they shouldn’t. And in business settings, they help track foot traffic and improve responsiveness at entry points.
