Smart Door Receptionist with Smart Lock System Using IoT

• Security and safety are increasing day by day and with improvements brought in the past decade and innovations to bring comfort in our lives. In today's world technology has become a part of an integrated part of society and therefore the security of an individual's home, office, or organization had to be considered with utmost priority. Smart Receptionist with a smart lock system is therefore mainly designed and developed for security system purposes. The smart security system is used in situations to see visitors when the main door of an office or organization is closed. The purpose of this system is to control the door lock using Blynk 2.0 Mobile Application and Raspberry Pi.
• In this system whenever a person rings the bell, the image of the person is captured by the camera and then the smart lock system will send the image to Blynk 2.0 Mobile Application. Once the image is uploaded on the Blynk 2.0 Mobile Application, an option will be available to either unlock the door or keep the door locked. If the person accepts the permission to enter, then the system will open the door, and if the person denies the permission to open the door, the door will remain locked and the system will display as well as speak out a message as “Access Denied”.
