IoT based Smart Security and Surveillance System

Internet of Things (IoT) is an escalating trend in today's world, and has proved to be a game changer in the field of technology. More and more sensors and devices are being connected together to develop new systems to solve real world problems. With the increase in technology and automation, security has become a major concern. The first line of defense for any property is always a security system, which alerts the owners regarding intrusion in real time. Currently, there exist multiple security systems, which make use of various motion sensors to detect any motion and notify the owner about the intrusion. However, most of these systems do not provide the features of zone barriers, facial recognition, remote camera surveillance and power failure detection, combined with ease of use, economic viability and power efficiency. The main objective of the proposed architecture is to overcome all these problems by developing a smart security and surveillance system which makes use of multiple ultrasonic sensors to detect intrusion attempts on the property of the owner, in order to notify them of the presence of an unauthorized person. Also, the system provides a warning to the person who has intentionally or unintentionally entered the property, so that they can step back in time, without triggering any alarm. With the help of a remote camera surveillance feature, the owner can monitor the surroundings of their property remotely. This system will issue an alert to the owner in case of a power failure as well. This system provides face recognition as an authentication procedure, in order to allow the valid entrants to enter into their property. All these features combined, create a flexible and reliable security system, which can be used in various properties, such as homes, offices, museums and so on.
