Intrusion detection is a crucial facet of contemporary security systems, designed to identify and respond to unauthorized access or malicious activities within a protected environment. These systems employ a variety of technologies and sensors, such as motion detectors, cameras, and door/window sensors, to monitor and analyze the surroundings in real-time. When unusual or suspicious behavior is detected, the intrusion detection system triggers alarms, alerts, or automated responses to notify security personnel or take corrective actions. Intrusion detection plays a pivotal role in safeguarding not only physical spaces but also digital networks, where specialized software monitors for unusual patterns or anomalies in user behavior. As a proactive security measure, intrusion detection systems contribute significantly to minimizing the impact of security breaches, enabling swift responses to potential threats and reinforcing the overall resilience of the security infrastructure.
