Development of triple streaming (HD-SDI, EX-SDI, analog signals) hybrid CCTV camera

Abstract

This study proposes the developing and implementing of the high-definition level triple streaming hybrid security camera that can output three types of video-signals, which are high-definition serial digital interface, extended serial digital interface, and analog signals. In this study, to develop the high-definition level triple streaming hybrid security camera the hardware and firmware software was designed and implemented. The hardware was implemented using image sensors MN34229PL from Panasonic, main processors EN778/EN331 from Eyenix, Auto Iris functions KA909A from Fairchild, and Zoom/Focus controls A3901SEJTR-T from Microsystems Inc. In addition, to evaluate the performance test of the developed camera in this study, we requested for the performance evaluation at the broadcasting and communication convergence testing by the department of Telecommunication Technology Association, Korea. The results of the performance tests indicated that the performances of the product developed in this study were found to be excellent than the other commercial products with regard to the signal-to-noise ratio, the minimum intensity of illumination, and power consumption. The product designed in this study is expected to be widely utilized in the high-resolution security camera market.
