AN OPTIMAL VIDEO CAMERA BASED SECURITY SYSTEM
ABSTRACT
This project consists of a video camera, 4 sets of IR transmitters and detectors, stepper motor and a computer system. The sensors, placed at four distant positions are connected to micro controller unit, where the data available from the sensors are processed. When the intruder comes in, the IR SENSORS will be obstructed and send signals to the micro controller unit (89c51). Micro controller unit switches on the camera, which is mounted on the stepper motor, computer system and buzzer. Stepper motor rotates to the direction of the respective sensor position, and then the image of the object will be captured and displayed on the system screen.
