Abstract:
Traditional surveillance systems in the modern context of security is pretty passive and thus always needs human supervision to monitor the accidentalities. Such dependency is usually characterized by slow reactions and unidentified security attacks, which makes such systems ineffective in proactive mitigation of threats. In this project, the proposed system is called Guardian, an autonomous AI-based smart surveillance system aimed at moving the security infrastructure past passive recordings and moving it to real-time active intelligence.
The main goal of the study is the creation of a cost effective and scalable solution that can recognize authorized personnel, intruders and recognize suspicious objects without human intervention. The architecture is based on a strong Edge AI platform, with Raspberry Pi as a processing device to process video on the device and thus reduce bandwidth consumption and latency.
In case of facial recognition, it uses Haar Cascade and HOG (Histogram of Oriented Gradients) classifiers to detect faster and then the Deep Learning-based encoding model to identify the accurate identity. The system incorporates YOLOv8 (You Only Look Once) which is a modern object detection algorithm to increase situational awareness by registering possible security threats like suspicious baggage or weapons.
The hardware architecture has a dual-camera logic (Entry and Exit nodes) which facilitates the accurate recording of entry/exit timestamps and computing of durationof-stay of each person. Firebase coordinates all the detection activities in real-time and delivers actionable alerts to a cross-platform application built using Flutter and can be viewed on the web and mobile platforms. The system is user-friendly to a Software-asa-Service (SaaS) model, differentiating between personal and corporate users, thereby opening superior AI-powered surveillance to a wider group of individuals. As it has been tested, the system has a high detection accuracy in under one second latency, which confirms its ability to be a reliable substitute to the traditional security measures.
