Surveillance Door-Gates Authority Based Cloud Computing for Global

The Internet of Things (IoT) has reached a golden age of explosive expansion in the modern era. In this system, the Raspberry Pi chip serves as the computer, while the Pi camera monitors a business gate. When a visitor wants to enter the business, he must first touch the bell button, which activates the algorithm. The camera then snaps his photo and sends it to the IoT center through email, which is sent directly to the cloud server. It is possible to control the door lock online. This technology makes it possible to save visitor evidence as a record in the event of an emergency. Here, those who are authorized to enter the company are only allowed by opening the gate and providing a voice message to those who are not allowed to enter indicating the reason after the image has been verified by the appropriate IOT center.
