IoT Based Multi-layered Security & Automated Monitoring System

This paper presents a multi-layered security project consisting of laser, ultrasound, heat, fire and gas detection with fault-tolerable monitoring and alarm system, that is fully automated and targeted to achieve minimum cost with maximum effectiveness. It redefines and improves security concepts like automated intruder detection via multiple security layers, such as-Laser and Ultrasonic detection systems. When one security layer fails to provide detection, the other layers remain effective. Also, it provides security monitoring via multiple network layers such as - TCP/IP communication and Blynk server and the monitoring remains active via any of the two layers when the other one fails. Security monitoring has become an essential part of achieving effective security at home and office. But, the cost for popular security solutions like closed-circuit television (CCTV) and internet protocol camera (IPCAM) are very expensive and quite complicated for installation and maintenance. Therefore, the entire project proposed in this paper focuses on developing a sustainable security solution that comes at a minimum cost. In this project, many features of internet of things (IoT) are utilized to design and configure a security system that requires no additional requirements for maintenance once installed. Most importantly, the overall cost of implementing the system is way below any currently available consumer security solutions. Consequently, it becomes easier for the average consumer to afford cost-efficient security systems. The following project is developed in a manner that it can be manufactured on a large scale in future.
