IoT-Based Smart Doorbell Using Raspberry Pi

Abstract

Security in home is now being directed from traditional methodologies to automation with the help of Internet. The Internet of things is the network of interconnecting devices (may be physical devices, vehicles, home appliances, etc.) embedded with electronics, sensors, etc., to exchange data. Nowadays, home systems are equipped with computing and information technology which provides them with smartness and intellect. Since doors are the gateway to our homes, therefore it is necessary to make them more secure. Currently available mechanism of providing secure access to doors includes bare-metal locks and some smart locking systems. The smart locking system’s performance can be evaluated on the basis of identification accuracy, intrusiveness, and cost. In this paper, we introduce the idea to provide secure access to home. It will be achieved through smart doorbell which is a cost-effective alternative to currently its counterparts. Our system connects WiFi-enabled Android devices with firebase server using Raspberry Pi and enables user to answer the door when the doorbell is pressed. It learns to identify new user by using face recognition as a unique identity to authenticate the individual.
