-
This project work deals with the use of Direction/Location Display which is capable of detecting intrusion at any location, sound and alarm and display the exact location of the intruder using seven segment displays. This project work is realized using top down methodology with active and passive components available in the local market. It is realized in different modules, all combined to form one function unit. The inputs are opto-couplers configured with laser diodes and light Dependent Resistor. (LDR) which act as the electronic eyes installed at the sensory points.
The control unit is made up of one short delay circuit, audio frequency generator, priority encoder and decoder, piezo-buzzer and single digit seven segment display. The system is packaged in a well-furnished wooden material. This system does not record/display the intruder. In a case of simultaneous intrusion, the display shows the location with the highest priority. And the system is powered from a mains supply. The result being a system which can detect intrusion, sound an audible alarm and displays the exact location of the intruder. It has a wide a range of application in surveillance especially in industrial and home security.
