Project Description: The Solution provides three levels of security check and blocks unauthorized access. Even if the intruder bypasses one of the levels, the variety of techniques used makes it highly unlikely, if not impossible, to break all the levels.
At first level, photo sensor actively monitors for presence of moving object. Any intruder must pass through the path where invisible sensors are waiting to intercept. Within fraction of second, the presence of intruder is sensed and immediately main door is locked, stopping any further movement of intruder.
If intruder is somehow successful in passing undetected, next LDR lights in the DARK room are waiting to welcome. As soon as intruder enters DARK room, laser light raises high volume alarm to all security persons. The main door is also locked. So that intruder can not go out.
Even if intruder is able to bypass level 1 and level 2, authentication is waiting at level three. One wrong password, and alarm is raised as well as main door is locked. There is no way that unauthorized person can open the Valve Gate, inside which all critical assets are present.
