SMART INTRUDER DETECTION

Abstract: The motion detection–based security system, designed by the engineering team, is among the most essential security projects globally, created due to their focus on unauthorized intrusion during restricted time periods (Zhang et al., 2020). The project involves a layered response mechanism, and automated alerts reflect the connection between technology and safety, with elements such as monitoring, alerts, deterrence, and escalation (Patel & Singh, 2019). The designers used motion sensors for monitoring, detection, and vigilance, with repeating cycles from the surrounding environment and the specified night window (Kim & Lee, 2021), and an IoT-based communication module created smooth and slightly immediate notifications, where triggers outline motion and messaging changes to an audible alarm (Gubbi et al., 2013). The response phase contains deterrents such as high-intensity lights, audible alarms, and emergency contacts (Sharma et al., 2022), while the initial phase contains subtle alerts, with layers of automated responses contributing to the secure appearance of the household’s perimeter, operating from 23:00 to 04:20 (Alam et al., 2020). The system implies protection through automated alerts and deterrent actions, with delay for escalation to local security authorities or a police patrol (Borgia, 2014), comprising three stages with a primary contact and two additional emergency contacts, emphasizing residents’ safety and reduced risk of harm (Sivaraman et al., 2018).
