Artificial Intelligence (AI) and the Internet of Things (IoT) have significantly transformed the landscape of physical security in facilities, making it more proactive, intelligent, and efficient. Traditional security systems largely relied on manual monitoring, isolated devices, and reactive responses, which often resulted in delayed action and human error. The integration of AI and IoT has shifted this paradigm toward automated, interconnected, and predictive security frameworks that enhance the safety and protection of people, assets, and infrastructure. IoT plays a foundational role by enabling a network of interconnected devices such as sensors, cameras, access control systems, alarms, and environmental monitoring tools. These devices continuously collect real-time data from different parts of a facility, creating a comprehensive and dynamic picture of the environment. For example, motion detectors, smart locks, surveillance cameras, and fire detection sensors communicate with each other through a centralized system, allowing seamless coordination. This interconnectedness ensures that any anomaly, such as unauthorized access or unusual movement, is immediately detected and communicated across the system. AI enhances the capabilities of IoT systems by adding intelligence and analytical power to the vast amount of data generated. Through machine learning algorithms and data analytics, AI can identify patterns, detect anomalies, and make informed decisions without human intervention. For instance, AI-powered video surveillance systems can distinguish between normal and suspicious behavior by analyzing movement patterns, facial expressions, and object recognition. Unlike traditional CCTV systems that require constant human monitoring, AI-enabled cameras can automatically flag unusual activities, such as loitering in restricted areas or the presence of unauthorized individuals. One of the key applications of AI and IoT in physical security is smart surveillance. Advanced cameras equipped with AI can perform facial recognition, license plate recognition, and behavior analysis. These systems can maintain watchlists and alert security personnel when a known threat or unauthorized person is detected. In large facilities such as airports, shopping malls, or industrial complexes, this capability significantly improves situational awareness and reduces the burden on security staff. Moreover, AI can
