Traditional door locks rely on mechanical structures for passive defense, while a new generation of smart door locks is achieving a comprehensive upgrade to active security, becoming the first intelligent line of defense for families. Current mainstream products generally integrate functions such as abnormal loitering detection, anti-pry alarm, wrong password lockout, duress alarm, real-time snapshot, and remote push notifications. When someone lingers at the door for a long time, forcibly pries the lock body, enters the wrong password multiple times, or attempts unauthorized access, the door lock will automatically sound an alarm and synchronize the information to the user's mobile phone, realizing pre-warning, in-event intervention, and post-event traceability. At the hardware level, Grade C lock cylinders have become standard, meeting the requirements for anti-technical opening time, and the panels are made of high-strength alloy materials to enhance anti-destruction capabilities. At the software level, local encrypted storage, offline availability, and communication encryption designs reduce network risks and the possibility of privacy leakage. Some high-end models support scenario-based functions such as door not fully closed reminders, door ajar alarms, and child departure notifications, comprehensively covering the details of home security. Industry experts stated that active security is a sign of the maturity of the industry's technology. Smart door locks are no longer just "door opening tools" but have evolved into home security hubs integrating identification, perception, judgment, and linkage, promoting home security from "post-event remediation" to "pre-event prevention" and significantly enhancing residents' sense of security and peace of mind.
