Reliable home security is vital for progression of our societies. Traditional methods to protect house premises against intruders include security guards and CCTV cameras which is labor intensive, expensive and unreliable. In this paper, we propose a wireless, intelligent, affordable and portable IoT based home security system. The input unit consisting of multiple sensors is placed at the entry points of the house. The SONAR, motion and sound sensor capture the situation at entry points. The sensor data is collected and wirelessly transmitted by NodeMCU to the Raspberry Pi server via an online database. The server uses logistic regression classification algorithm to detect human presence at the gate. Once intruder is detected, alerts are generated to the user and camera mounted on the input unit is turned on to take pictures. Facial recognition unit is also incorporated to detect known versus unknown faces. The information of intrusion including image and timestamp are send to the Shield's mobile application.
