ColorVU bullet camera with IP technology and 4 Megapixel resolution. Fixed optics 2.8 mm. H.265+ / H.265 compression. IR LEDs 30m. WDR 120 dB For outdoor IP67. ColorVu technology that incorporates advanced lenses and high sensitivity sensors. In contrast to conventional lenses, ColorVu lenses are equipped with a super aperture, up to F1.0, which allows more light to enter the lens and thus increase the brightness of the images. The lenses of HIKVISION™ ColorVu cameras also incorporate a Wide Band Anti-Reflective Layer (BBAR) and Extra Low Dispersion Optical Glass (ED) to reduce glare and efficiently reproduce the sharpness and color saturation of an image. These technologies effectively retrieve the key information that flashes can block.
