Door and windows provides mean of entrance of people in house any time but amazing thing is that we never know whether they are good or bad. For instance robbers who are coming during night time while house holders are sleeping they are using doors and windows to take properties, and kill owners of house because of sleeping.
Security is a measure taken to guarantee the safety of a person,
property or organization. A house equipped with a modern security is
definitely not an easy target for robbers.
