The idea of Closed-Circuit Television Surveillance has its roots associated with ‘Anableps anableps’ or the four-eyed fish. This freshwater fish trap its prey with the help of natural surveillance system imbibed in its four eyes. Floating on the surface of water it feeds on insects and aquatic invertebrates by seizing best view of both the air and the water.



In fact the fish has only two eyes each split into two sections taking care of air and underwater view at the same time.
