Summary
The project presents an IoT based autonomous alarm and access control system
that can automatically switch on the alarm system when the last person leaves the
premises. Mostofthealarmsystemsusedintheorganizationsaremanualandhuman
involvement is required to arm them. The manual arming of the alarm system adds
an extra layer of responsibility on the user of the system and gives birth to lot of
other problems that are discussed in the thesis.
However,thesystemproposedbyushelpstoovercomeproblemsfacedintheman-
ual alarm systems. Our system is also like any other alarm system but is powered
by the latest wave of computing known as Internet of Things. Our IoT based system
is cost effective and provides much more functionalities than the normal alarm sys-
tem. A prototype is also developed and tested in the real environment to prove the
feasibility of the system.
