A smart door lock system is a system which uses digital password for opening and closing the door. With the advancement of modern technologies areas related to robotics and computer vision, real time image processing has become a major technology under consideration. So here a try has been made for a novel approach for capturing images from the Pi Camera in real time environment and process them as we are required. Here in this project depicts a basic and simple equipment execution of face location framework utilizing Raspberry Pi, which itself is a minicomputer of a small estimate and is of a low cost. The framework is modified utilizing Python programming language. The destinations of the face recognization are to recognize appearances and its spatial area in any pictures or recordings .The proposed framework distinguishes the faces present in a grey scale and colored image. Here in this project the idea of identification has been built up by composing distinguishable code for dataset generator, trainer and indicator. Effectiveness of the framework is examined by as certaining the Face recognization rate for every one of the database. At last the data that will be shown alongside recognized photograph has been put away on database. This concept has a higher scope on security and surveillance projects and various operations.

INTRODUCTION In the proposed approach, a smart door lock and lighting system using IOT for smart home is presented with the additional add on feature of facial recognition. A smart door lock system is a system which uses digital password for opening and closing the door. The door lock is the foremost and endmost thing people come across in entering and leaving their homes respectively, the home automation function in digital door lock system allows users to comfortably control and monitor home environment and situation all at once. It also allows users to remotely overlook the situation inside the house through World wide web or any other public network. A smart lighting is proposed which can be remotely controlled using Internet. Nowadays, technology is an integral part of everyone's lives. It influences several facts of everyday life and allows improved social synergy, easy transportation, the capability of indulging in entertainment and media and helps in the advancement in medicine. Internet has played a pioneering role in providing immediate solutions for various problems and has given the ability and has connected all the remote places which has contributed to significant reduction in cost and also energy consumption. Home automation or intelligent home is defined as initiation of technology inside the home surroundings to provide ease and safety to its inhabitants. The technology of the Internet of Things is used to examine and execute home automation. GPRS, GSM, Bluetooth, Wi-Fi and cellular networks support remote data transferring and are used to enter abundant levels of acumen within the home. Home automation has the ability to greatly assist and improve the quality of life of older people. IOT also greatly contributes to supply management and observance with ease of control. The user can remotely control the gate, home appliances, etc. comfortably and conveniently anywhere and anytime. The Internet of things (IoT) is known as connecting objects like cell phones, personal computer and other devices to the world wide web, which introduces a new era in the area of communication, where objects communicate with each other without human intervention. Most of the equipment and gadgets are controlled and monitored to help and assist humans. Moreover, various wireless technologies assist in communicating with remote places which play a great role in the intelligence of house surroundings. IOT is a sophisticated network of nodes with the unique ability of exchanging data and knowledge wirelessly which enables communication between two objects thereby making them smart and omitting the need of humans for machine to machine communication.
