HIDDEN ACTIVE CELL PHONE AND CAMERA DETECTOR

Abstract

In our day to day, the usage of mobile phone and camera can be increased in restricted places. The main scope of theproject is to sense the presence of an activated mobile phone and camera from a distance of 10 meters to prevent the use of same in the examination halls. This detector is used to find the mobile and cameras in restricted places like examination halls, theatres, trial rooms etc.,The radio frequency signals are transmitted from wireless camera and mobile phone during video transmission, sharing messages, taking snaps, incoming & outgoing calls. The detector will detect the transmitted signal and it is given to the microcontroller. After receiving the signal, the microcontroller turns on the beep alarm and the information is displayed on the LCD. It is used to detect activated mobile phones and wireless camera by the RF signals which are transmitted.
