When human vision is no longer the only game in town, don’t leave home without this unique umbrella studded with infrared LEDs, designed to flirt with computer vision algorithms of advanced surveillance systems. The umbrella consists of 256 infrared LEDs inserted into its canopy powered by lithium polymer batteries concealed in its stalk. These LEDs are visible only to CCD surveillance systems set to night-vision mode. These systems commonly track figures using a sophisticated algorithm to distinguish moving objects in the foreground of an image from a static background. By turning the umbrella on and off, you can alter the registration of foreground and background pixels stored in system memory, thereby frustrating attempts by the algorithm to track moving objects in the image.
