Design and Implementation of an RF Home Security System Prototype

This article presents a report on the prototype design of a Smart home RF security system using predictive analytics. An infrared transmitter sends 38KHz constantly to an infra-red receiver to form a security line. The moment a disturbance is detected, a trigger LED flash is activated and then an encoded RF signal is transmitted through a 433MHz RF Module to a latch decoder. A microcontroller verifies the exact security code and uses it to activate relay switches. This is connected to a USB cable into a computer with infused camera. A timer is then setup for less than 5secs in order to trigger the camera. The camera snaps for 90secs and stops while all the captured images on the scene are stored on the hard disk of the laptop for further analysis.
