Abstract

In today's world, every household is required to have a home security system installed. Before
recently, most doors could be opened using traditional methods such as keys, security cards,
passwords, or pattern locks, but this has changed. Accidents like losing a key, on the other
hand, have resulted in much more concerning scenarios such as robbery and identity theft
than the loss of a key itself. This has progressed to the point that it is now considered a major
problem. In order to overcome this problem, the development of facial recognition technology
was conducted, and the Internet of Things (IoT) was also used in the effective installation of a
door access control system. In addition to serving as the primary controller for face
recognition, the youth system, and the locking system, the Raspberry Pi is also employed as a
tiny computer board that can be programmed. The person who is standing in front of the door
is photographed with the aid of a camera, which is mounted on the wall. If the face is not
recognised by the system, a warning will be generated. Using Internet of Things (IoT)
technology, a user may control the access to a door.
