Smart Wi-Fi Doorbell Using Esp32cam with IoT

Regardless of whether they are present at the moment, people need to know who is visiting their organizations regularly. For those who experience a disability that prohibits them from meeting the visitor, this need is much more pressing. This paper suggests a smart doorbell that performs the function of a doorbell to address this issue. It should identify the visitor and notify the user. This proposal includes technology for visitor facial recognition, user alerting, and reaction management to do. The entire procedure, including visitor recognition, user notification, related management challenges, interconnected stages, and standardization concerns, is covered later. Finally, three scenarios were combined to test the model's efficacy. Each scenario was made up of several organizations, and an analysis of the recognition of known and unknown individuals was conducted across each scenario.
