The framework involves two segments. The principle area is camera locating segment during which focal point of the camera is detected using Image Processing techniques and the second segment is the camera deactivation segment which depends on Arduino. In this segment, Arduino directs the IR transmitter towards the recognized camera and a solid infrared light is anticipated into camera focal point in order to neutralize the images captured by the detected camera. The infrared light projected is neither a health hazard nor interfere in cameras operation. Both these units are in synchronization with one another.

INTRODUCTION Computerized cameras, smart phones with cameras and hidden cameras are exceptionally basic nowadays. In spite of the fact that photography is denied at places such as theatres, historical monuments, changing rooms, museums, courtrooms and so on user consistently attempt to capture images of the site secretly which isn’t worthy. Movies as soon as they are released are recorded and put up for public use before the genuine legitimate CDs are made accessible in the market. Film industry suffers heavy loss due to piracy at theatres. There emerges a need to prevent this undesired photography as to avoid this overwhelming misfortune. Hidden cameras at open spots are making a major issue in keeping up secrecy of people. These cameras are very small which cannot be detected by naked eye and they are put up in changing rooms and shopping centers which represent a significant danger in maintaining security of individuals to the privacy of people. So by considering all these threats and issues we have come up with a solution to detect and deactivate cameras at photography denied territories. On the other hand the system should not cause any damage to the camera or the user. The framework created identifies cameras in prohibited area and transmits solid confined light beam at each device to neutralize it. As we are utilizing infrared beam for neutralizing computerized camera, it is neither a health danger nor it will affect the detected cameras operation. Luckily, most weapon systems have a typical feature of optical sight which resembles with camera lens, so identification of cameras or other optical gadgets out of sight could assist military powers with detecting a potential assault. The sooner a danger is identified the better, and in this way a strategy that can identify a risk before being initiated is supported. so this strategy likewise is valuable in defence areas to identify possible attacks. The project is beneficial at places like museums, historical monuments, changing rooms, public rest rooms, theatres, shopping malls, jewellery shops, courtrooms, defence areas and so forth. 2. LITERATURE SURVEY: A number of systems are already developed which uses different techniques for anticipation of photography in disallowed territories. But most of the solutions are complex, inefficient and they require some sort of instrumentation of the capture device. Arjan L.Mieremet [1] proposed a system “Modeling the detection of optical sights using retro-reflection”. In this paper, it is descried that when light is projected on optical sight, the radiation is gathered by the focal point and sends back to its original source. This effect is known as cat’s eye effect and the property is known a retro reflection property. Vaishali kaul [2] published a paper “Hidden camera detection” 2017. In this paper an application is
