The BU5 Series is Pelco’s general purpose integrated IR bullet CCD camera. It uses a group of integrated infrared LEDs to deliver high quality pictures, even at night with zero illumination. Its day/night technology provides outstanding performance over a wide range of low-light conditions. The camera uses a removable infrared (IR) cut filter to switch between color and black-white modes as environmental lighting conditions change, and when the need for infrared sensitivity is realized. The BU5 Series also uses adaptive tone reproduction (ATR) technology to compensate for gradation of subjects to an optimum level and provides high performance video quality over a wide range of lighting conditions.
