Conventional surveillance dome cameras have employed a slip ring between camera a head and body in order to pan endlessly. We have developed the technology of contactless image signal and power transmission, so that we make the life of cameras' panning much longer from a million revolutions to 20 million revolutions due to eliminating the slip ring, whose abrasion deteriorates cameras' life span. Images are transmitted by optical coupling and power is transmitted by inductive coupling. We also succeeded in making the unit of cameras' revolution smaller and thinner because a reduction gear and a ball bearing could be united.
