GSM & PIR Based Advanced Antitheft Security System

Abstract : Security is a too much important thing to be concerned in our day-to-day life. Everyone wants to be secured as much as possible. Knowing our home or shop is secure provides us peace of mind. We know now a day’s theft has become a major issue. In this paper we design an advanced electronic security system by using small PIR and IR sensors built around the arduino controller. PIR and IR sensors sense the presence of intruder & Controller reads the signal from sensors and if intruder is detected it turns on the buzzer& the lights in the room as well as making a call to predefined number through a GSM modem. At the same time controller also turns on camera to capture the image of intruder.

 EXISTING SYSTEM :

 ? Security and crime control concerns are the motivating factors for the deployment of video surveillance cameras. ? There are many methods of identification, but the most general is to store a unique serial number that identifies a human or object on a microchip that is attached to an antenna. ? Depending on the tag type, the energy is "harvested" by the tag's antenna and used to power up the internal circuitry of the tag. ? The tag will then modulate the electromagnetic waves generated by the reader in order to transmit its data back to the reader. ? This technique just uses the cameras to do surveillance. It needs a command and control center to monitor all the activities using cameras.

 DISADVANTAGE :

 ? A variety of security devices for deterring, detecting and identifying offenders or intruders can be found. However, very few provide a working relationship to a room. ? An intrusion deterrent device which activates a water spraying system has been invented. ? A triggering mechanism for a tear-gas canister was introduced for the purpose of security and protection, but this idea did not have a working relationship to a room. ? Security devices to identify the bank robbers using the spray gun to discharge a scent which can be detected by the dog have a working relationship to a room.

 PROPOSED SYSTEM :

 • In this proposed system, the home based smart surveillance system which evaluates the development of a very Low-cost security system using PIR (Pyroelectric Infrared) sensors and video cameras built around the PIC(Peripheral Interface Controller) microcontroller. • In this time,the system triggers an alarm detecting the presence of unauthorized person in a specific interval of time and simultaneously sends a message to the SMS through GSM Modem. • When the security system is activated, the CCTV camera is activated. • This highly reactive approach has low computational requirement. Therefore it is well suited for home surveillance system.

 ADVANTAGE :

 ? There are several terminologies that are used extensively throughout this paper such as Global System for Mobile Communication (GSM), SMS, etc. ? Through the integration of information technologies with the home security, systems are able to communicate in an integrated manner which results in convenience, energy efficiency and safety benefit. ? Home security system is adopted for reasons of ease, security and energy efficiency. ? The distributed network intelligence will allow an intruder alarm system to react to multi-signalization intrusion situations in much more efficient ways, being also able to distinguish more accurately real security violation adverted operations.
