These Days, Safeguarding Resources Primarily Involves Security. Because There Is A Greater Chance Of Theft And Infiltration, Security Is Crucial. In Order To Safeguard Banks Against Fire And Other Unusual Activity, Security Is Also Required.Numerous People Use A Variety Of Security System Kinds. In Our Research, We Employ Microcontrollers With Various Sensors (PIR, Smoke Or Fire, IR, And Gas) As Observatories To Detect Or Identify Intruders Or Anomalous Behaviors Inside The Bank And ATM. We Have Observed That The Majority Of Security Systems Are Built Just For Alarm Utilizing Microcontrollers.The Primary Goal Of This Research Is To Create A System That Can Automatically Detect And Apprehend Theft From A Central Monitoring Unit In The Bank Or ATM. The System's Objective Is To Utilizing IOT Technology, Create A Centralized And Intelligent Monitoring And Control System.
