, Description:DESCRIPTIONS:

With the advancement of the Internet and Wireless Sensor Network Technologies, a new concept known as the Internet of Things (IoT) has emerged (things or objects like sensors, actuators, RFID tags etc.). Internet of Things (IoT) devices is those that operate without screens or user interfaces in resource-constrained environments. A number of issues, such as battery life and storage capacity, as well as security concerns, must be addressed in the Internet of Things. The Internet of Things (IoT) device collects and analyses data about human behaviour intelligently. Because of the high level of connectivity among these intelligent objects, there are serious security concerns. The Internet of Things (IoT) is a network of sensor objects (sensor nodes) that can communicate with one another via the Internet while engaging in external activities. Any communication device with a unique identifier can connect to the network. The Internet of Things can benefit a wide range of industrial, scientific, agricultural, and transportation systems. According to Gartner, the number of smartphones and tablets sold will reach 7.3 billion by 2020. As the Internet of Things continues to grow at a rapid pace, communication networks are finding it increasingly difficult to handle massive amounts of data while conserving energy, preventing security threats, and maximising the efficiency of cryptographic algorithms. In our day and age, the concept of home security has grown in importance. As technology advances, the world becomes more intelligent in every way. These ingenious devices are invading our lives, but they do so while respecting our right to privacy. The Internet of Things (IoT) allows these devices to monitor anything connected to the internet. In today's digital world, closed-circuit television (CCTV) surveillance cameras are required to record every action. It is impossible to constantly monitor CCTV footage or inspect the door every minute, just as it is impossible to inspect the door every minute. Another requirement is that our premises be monitored; if a stranger is seen standing in front of the entrance door, an alert must be sent to our staff immediately. When a visitor knocks on the door, our Smart Doorbell can send a notification to the owner's smartphone. When someone knocks on the door, our Smart doorbell uses the Internet of Things (IoT) to send a notification to the home's resident's smartphone. The smart doorbell can be networked and used to collect visitor data, which it can then send to the cloud or any other storage device of your choice. If there is a break-in at the house, we will have video evidence because we have it on hand. These systems serve only one purpose: surveillance. In the event of an unexpected event, the camera's footage can be used to provide eyewitness testimony for post-event analysis. The system can notify the homeowner when a visitor arrives at the front door. Because this surveillance occurs around the clock, the system requires a large amount of storage space in order to keep track of all the footage. Because these devices are linked to wireless networks, continuous video capture necessitates a higher memory requirement for the device in question. The Raspberry Pi's small size makes it simple to create intelligent communications for motion-detection applications. When a member of the family is frequently away from home, the Smart Doorbell can be used to remotely monitor the premises from any location, including an office or a business. The Internet of Things (IoT) technology offers a secure and dependable solution. Prior to this, there were systems such as the GSM module and the pi camera, but they had a number of flaws, such as a delay in alerting the user and working with heavy equipment that was not portable. This paper proposes a low-cost method for keeping these networks running. Our Internet of Things (IoT)-based application notifies the homeowner as soon as an object is detected at the front door. Installing this system at a home or office's front door provides real-time monitoring that can be accessed from any location via the internet. Many people benefit from the fact that this automated system provides a safe, comfortable, and easy-to-access environment without the need for 24-hour video surveillance to be monitored by a human eye or replayed later to determine who was roaming around the home premises. When the system detects a potential threat, an alert message is sent, along with an image of the object in the message attachment. If the sender is known to the owner, he will respond positively; otherwise, he will respond negatively. In the second section, we will go over a lot of related work. The Third Section of this document contains detailed instructions on how to build a programme on the Raspberry Pi. Section Four brings our discussion to a close and serves as a wrap-up. An Internet of Things Smart Doorbell has been thoroughly discussed. You can monitor your home from anywhere using this system. The information provided by the smart security system can be accessed via mobile phones, tablets, and desktop/laptop computers for quick decision-making. When an object is detected, the system sounds an alarm and sends an e-mail to the user with an image of the object attached. We intend to identify the object as well, using some training data provided by the system, so that the system can identify the object itself before sending an alert to the user.
