IOT Based Smart Doorbell system Using Raspberry Pi 4
Project Area of Specialization Artificial IntelligenceProject SummaryThe smart doorbell system based on raspberry pi 4 enables smart communication between guest, a person standing on the door, with the person sitting in the home. The system uses internet-of-things (IoT) technology to connect all parts of system together and provide seamless interface to users (guest and owner). The proposed system, a low cost and low power consumption unit with enhanced security features, acts as security gateway for the guests entering the house. The system is installed with recognition model that recognizes people by learning on their distinct facial features. Moreover, the system is equipped modern tools that facilitate the guest to make video call with owner and seek owner permission prior to entering in the house.
Our solution will provide following features for houses and institutes;
- Real- Time SMS, E-mail, and video call communication.
- Quality: provide safe and reliable security system.
- Low-cost, low power consumption and free from complex wire connections.
- Equipment Efficiency including Raspberry pi 4B module, Pi camera, Push button, SD card and others, which are low cost and low power Consuming (Current, Voltages) units.
The solution's objectives are as under:
- Provides best smart security to the house owner.
- 99% accurate recognize the face of stranger.
- Economically favorable for country as it adds sustainable growth to local industries.
- Low power consumption.
- General-purpose security system that can be applied in various security applications.
- Real-time Notifications via E-mail or SMS and also video call to take immediate actions.
- Low cost based smart security system.
To summarize, the applications of proposed security system include surveillance, marketing, digital door locking, attendance system, face lock for mobile devices (e.g., snap chat), geo tagging, and law enforcement Agencies tasks.
Project Implementation MethodThe project implementation will be as fallows.
(a) In this project some advanced features are used like real time notification ,video call, security surveillance.
(b) this project meet standards for Commercilization due to advance features.
(c) Proper setup for Offices,institutes,houses . This solution for national and international organizations.
(d) setup for (ioT) upgradation and its safety.
(e) colud and programming Raspberry pi team.
(f) setup to target sales in specific institutes and organiztions in security issues environment.
Benefits of the ProjectSmart doorbell system`s benefits are listed below
- Knowing who is at your door (even you are not at home)
- To provide 100% security to home, institute, or any sensitive building/place.
- Avoiding unwanted access such as robbery and invasion.
- Decrease additional expenses on security guards and other security systems.
- Wireless connections (save wire`s money).
- Low power consumption and low cost.
The system is fully based on 4th Industrial revolution based technologies like IoT, Big-Data and Artificial Intelligence. The project technical flow will be as under;
- Pi camera will be used to recognize the visitor at door.
- Raspberry Pi 4B module will be used to collect the data from camera and push button, this will be used as edge devices to get data on ground and push on cloud.
- There would be gateway used, that will provide secure, reliable & authorized connectivity with physical and cloud layer.
- There will be a cloud which will be capable to hold highly frequent data from edge device from camera and button.
- There would be front application to access all houses, private organizations/ institutes and government institutes systems for owner/head monitoring.
