Due to the dim lighting of the bar stage live broadcast, the real-time requirements for display types are relatively high. Generally, a full HD SDI signal + HDMI signal interface camera is more suitable. However, some bars belong to the performing arts bar, and occasionally there is strong light and color light. If only high-definition display is difficult to meet, at this time, it is generally suitable to choose a camera that converts color to very black and white and has a dynamic bandwidth. It is easier to adapt to the short-term change of strong light.
Meet the basic display requirements of color or black and white image quality. Want to record wonderful and clear performances, so it is fundamental to meet the basic technical needs according to the needs of users. There are several cameras suitable for live broadcast in the dark environment of bars, which are worthy of reference
