yes I'm looking for a job and paid consultancy to obtain at the end a fixed system to manage entrances to apartments given for short-term rental such as airbnb. So a video camera such as HIK VISION DS-K1T343MWX to be connected to an ARDUINO board with ESP32 expansion or similar to communicate with a smart key ring such as ARREGUI Keeper E-SEGO14.The facial recognition camera (with RJ45 - RS485 connections) could send the result to the Arduino board which in turn could give the ok to the key ring via Bluetooth.
