Abstract: A high speed dome camera includes a stationary unit, a moving unit including an image capturer for capturing an image signal, and an optic-electric slip ring arrangement provided between the moving unit and the stationary unit which includes an electric unit for power transmission, and an optical unit for transmitting the image signal from the moving unit to the stationary unit when the image capturer is driven to rotate in a high rotational speed. The optic-electric slip ring arrangement prevents the reduction of the quality of the high definition transmission, so that the present invention has the advantages of the higher transmitting speed, broader signal band, less signal distortion, and higher reliability, so as to increase the rotational speed.

Abstract: A speed dome camera includes a stationary unit, a moving unit rotatably mounted to the stationary unit, and a wireless signal transmission module. The stationary unit includes a mounting base and a signal processing module supported at the mounting base. The moving unit includes an image capturer and a controller module operatively linked to the image capturer, wherein the image capturer is adapted for obtaining an image signal when the image capturer is rotating. The wireless signal transmission module is operatively linking the stationary unit with the moving unit for wirelessly transmitting the image signal from the image capturer to the signal processing module. Therefore, the high definition image signal is able to be wirelessly transmitted from the image capturer to the signal processing module while the moving unit is rotating at its maximum rotational speed of 400 degrees per second without affecting an image quality during wireless transmission.
