It is the duty of each and every one of us to protect the house which stands at the same time as our abode and the protecting shield.

In the past we had to rely on landline telephones to call someone when we went out of the house or for something urgent. As the seasons gradually changed, so did the facilities, and with the growth of technology came the ability to use and handle things comfortably anywhere, especially in communication. With the advent of the internet, more and more benefits began to be activated.

When we are in a hurry when someone comes suddenly, does it make the whole mind disturbed, when it comes to the confusions of who is probably not essential anymore? A facility is now being introduced to check who came out of the house and give them an answer.
