Our generation is smart, people are getting smarter by using smart technologies. Smart devices make life simple, easy, and secure too. Now talking about security, the general public has significantly worried about conceptual security either in family units or in workplace conditions. So the setup of Smart Lock is much needed in present condition. Using the conventional key locks there are so many difficulties like what if your keys are lost, or thieves may break through old locks or maybe they can get your keys somehow and breakthrough your house or workplace. Many studies have developed or tried to develop Smart Door Lock in various techniques. But there is one thing to remember, not everyone can afford a high-cost security system wherein this vast population everyone needs an affordable security system or we can say smart door lock for them. So I am working on this to compare various Smart Door Locks already available and getting the conclusion which can be most affordable for all of us rather than only high profile rich people.
