Public buildings and private business locations have been using IoT for years. For example, cameras have been used to feed video to monitors, or to record anything that passes within their field of vision. Today, smart cameras are used to monitor and recognize people and things that enter, exit or move through buildings. The days of the “dumb” camera—feeding a continuous stream of images to a guard who is charged with viewing six or more screens and somehow, quickly, recognizing a potential threat—are numbered. Smart cameras—IoT devices that are built with embedded technology, like Intel Movidius technology, can recognize faces and objects.
Each camera can monitor and broadly recognize people and things that are passing beneath it—if something that is outside of normal parameters is detected, a guard who used to monitor endless streams of video can now be signaled, the video with the “suspicious” images can be quickly shared and assessed, and the potential threat addressed. There’s intelligence inside the camera, and field programmable gate arrays (FPGAs), specialized chips that run extremely rapidly and can be reprogrammed to switch from one task (for example, rapidly digitizing incoming video) to another (enabling specialty observation of a suspected threat) significantly increase the value of the smart camera.
