An intrusion alarm is an automated security system designed to detect unauthorized entry or suspicious movement within a restricted area. It typically utilizes a combination of door and window contacts, motion sensors, and glass-break detectors to trigger a loud siren or silent alert upon a breach. Modern systems often integrate with mobile apps, providing property owners with instant notifications and the ability to arm or disarm the system remotely. By creating a high-decibel audible deterrent and notifying monitoring centers, these alarms play a critical role in preventing theft and ensuring the safety of occupants.
