Detecting and Disabling Digital Cameras

The system locates the camera, and then neutralizes it. Every digital camera has an image sensor known as a CCD, which is retro reflective and sends light backing directly to its original source at the same angle. Using this property and algorithms of image processing the camera is detected. Once identified, the device would beam an invisible infrared laser into the camera's lens, in effect overexposing the photo and rendering it useless. Low levels of energy neutralize cameras but are neither a health danger to operators nor a physical risk to cameras.

The entire area to be protected is scanned by using infrared light. Infrared LED is used for producing them. The circuitry required for producing infrared beams are simple and cheap in nature. The scanning beams sweep through the vertical and horizontal direction of the area, to ensure no camera escapes from the device.
