The Internet of Things (IoT) improves home security systems by allowing devices to communicate and share information seamlessly. Connected **sensors** and cameras enable real-time monitoring, allowing homeowners to receive instant alerts and access live feeds via mobile apps. IoT devices can also automate responses to threats, such as locking doors remotely or sounding alarms when movement is detected. By integrating various components, IoT enhances the comprehensive security measures available to homeowners, providing peace of mind through increased situational awareness and control.
