Abstracts: Home Security and Automation is a wide and varied field that involves devices as small as temperature and light sensors, and as powerful and complex as modern mobile devices and smart phones. Market is currently dominated by the devices that feature security using motion sensors, video streaming of the visitor on the screen attached to the inner wall of the house, and automation using short message system (SMS). Here we develop a complete package of home security and automation that enables the user to keep an eye on their home using their smart phones. The device works on two modes, first, while we are at home and second, being away from home. As soon as someone rings the door bell, this device enables you to have the snapshot of the visitor, on your smart phone. Once you switch to the second mode of operation it directly dials a call to you, enabling you to talk to the visitor. If the call could not be connected or if you disconnect the call it plays the pre recorded message to the visitor. The complete system works over internet connectivity through your smart phones. The device at home is connected to internet via Wi-Fi. Now coming to home automation, we design an application that works on Android operating system, the highly used operating system for smart phones. Instead of accessing appliances through SMS we enable you to access it through an easy to use application on your smart phone. It allows you to switch on and off all the appliances connected to the main system at your home. This application works over internet, providing 24 hr connectivity without any extra charges. Being technically feasible, this concept works very well with the current evolving trend of smart phones giving you the feeling of security and accessibility.
