The BU4 Series is Pelco's entry-level integrated IR bullet CCD camera. It uses a group of integrated infrared LEDs to deliver high quality pictures, even at night with zero illumination.
The BU4 Series is a high resolution digital camera with 540 TVL of resolution and a minimum of 0.2 lux illumination in color mode. With the included IR supplemental lighting, the BU4 Series operates under zero lux (monochrome mode). The camera uses automatic gain control (AGC) to optimize the video signal.
The BU4 Series includes automatic white balance (AWB) for difficult lighting situations and digital noise reduction (DNR) that minimizes environment noise levels to produce clear image quality.
