Traditional surveillance systems, which primarily rely on manual monitoring through CCTV cameras, are often limited in their ability to provide realtime threat detection, continuous monitoring, and intelligent response mechanisms. This research presents the design and implementation of an advanced Surveillance Enhancement System that integrates Artificial Intelligence (AI), Internet of Things (IoT) devices, and realtime monitoring technologies to overcome the limitations of conventional security systems. The proposed system focuses on automating the detection of suspicious activities such as unauthorized access, loitering, object tampering, and abnormal human behaviors through the application of AI-based video analytics and IoT sensor integration. The system architecture includes high-definition surveillance cameras, motion and vibration sensors, acoustic detectors, automated alert generation mech
