DOOR KNOCKER
SMART DOORBELL
The simplest pre-electricity example of a visitor-announcement system
was the door knocker that makes a sound when the visitor banged the
hinged knocker onto the metal plate installed under it. Mechanical chimes
were made using a small bell, installed inside the house that was
manually activated when a visitor would pull a chain or string to ring the
bell. With advancement of time, doorbells are powered by electricity.
The number of sounds, physical designs and advanced features
available in door chimes today are nearly endless. Doorbells can now
be connected to smart phones to monitor home.

physical exchange. Telegraphic communication was a predecessor to
e-mail.
Now there are more ways to talk and send messages from anywhere
to any place. Technology paved way for people to connect easily and
in real-time.

DVD-quality video.
