In a case of intrusion while the user is out of the house, then the device sends SMS to the emergency number provided to it and also display it on LCD connected to it. The paper consists of a background into the area At mega 2560 microcontroller, sensing elements and GSM modem, how they are interfaced to each other and AT (Attention) commands set used in communication. This system can avoid these undesirable situations of burglary and theft. Th security system has features like changing the input password of the system and a user friendly visual and audible interfaces for the user to operate on. The main goal of this research is to aid and assist in intrusion detection and avoid criminal activities which include theft and burglary.
