Now-a-days theft has become a big threat to people and their property. Securing and monitoring has become the main objective for controlling theft. Several technologies have been developed to control theft. The existing technologies can control only theft but not the culprits who steal the properties. The proposed system is used to provide security to control theft and giving alert to owner when there is a break-in, using Bluetooth. The advanced locking system technology is implemented along with the traditional locking system. There are three techniques to prevent theft. First, IR sensor which is placed infront and rear side of the house. This IR sensor senses the object passes near it. Then the passcode lock system is used to detect the passcode is correct or not. If the entered passcode is incorrect the Arduino UNO controller will be activated. Third is using indicators, it consists of two switches. The two switches are considered as the main power line and fuse box which is placed at the house. When these two switches are on off mode it is considered as power cut. But incase only when the fuse box switch is off the controller activates automatically and the alert is send to the owner through the Bluetooth application which is installed in the mobile phone. If there is any interrupt in any of these techniques, the message will be send to the owner and police station. Total system shutdown option is activated using this application. Then the security system starts monitoring the house. This shutdown option can be made on whenever necessary. This may reduce the power consumption. Such security system gives service at low cost compared to the cost of the available security systems.
