In terms of house security, the doors are
playing important roll. To have the residence safe and
secure, the door will be kept locked by the owner at all
times. When sometimes, landlords left the house. the
landlords forget to lock the door, or the landlords are not
definite if they close the door or not. This paper will
represent a wi-fi base smart door lock system. It also uses
the ESP32 CAM module and telegram. In the working
system when a person presses the doorbell the landlord
receives a message on his/her mobile handset with the
photo of that person. This paper also represents that if the
owner wants to operate the smart lock with his/ her phone
he/she is free to do so or the landlord is able to open or
close the door with his/her phone after checking the photo
of that person. The ESP32 CAM and internet of things
(IoT) is used by this door security system to monitor and
watched the status of the door, so it enhances the security
of the home.
