Video Camera Detection

Abstract

This project is developed for the users to detect the availability of video camera. It has an inbuilt IR transmitter and receiver moving parallel to the screen. Normally the rays from the IR transmitter falls on the wall and returns back to the IR receiver. The IR sensor sends signal to the microcontroller. If the rays fall on the video camera lens, it wont come back. Thus the sensor senses no signal. Immediately it sends to the microcontroller. The microcontroller analyses the signal and sends signal to the LCD display through LCD driver. It also sends signal to the buzzer. Thus the user can easily detect the video theft inside the theatre. It uses PIC16F73 (28 pin Micro controller). The micro controller controls the complete operations of the project. The micro controller program is written in assembly language.
