Abstract
A single video camera itself can only capture/record which is in front of it. But when we want to capture/record opposite of it we have to rotate it. This is made simple by developing SOUND TRACKING SYSTEM.
This device at first capture sound signal through its microphones then after converting it into electrical signal it’s being passed through the filter to cut out surrounding noise. Selected signal range is passed towards amplifier to convert millivolts into volts so that microprocessor gets ON. Programmed microprocessor figure outs that which microphone’s signal is stronger than by attaching H-bridge motor, then motor shaft rotates towards that sound source to locate and record it through camera.
This module is very useful not only for video conferencing but also for security purpose.
