Part of Hikvision's enterprise range of network cameras, the DS-2CD5546G0-IZS is an outdoor motorised varifocal IR dome camera that produces an exceptional 4MP high-resolution video. Powered by Darkfighter and Lightfighter technology, this camera can produce clear and crisp images in environments with extreme background lighting or in ultra-low light situations. The DS-2CD5546G0-IZS includes an ideal combination of smart features for its affordable price such as 140dB true wide dynamic range (WDR), image sensor technology, a high definition image processing chipset, audio/alarm IO, smart video content analytics (VCA) and built-in EXIR 2.0 infrared technology providing up to 30m visibility at night. Additionally, this camera supports H.265 and H.265+ intelligent video compression, which reduces bandwidth/storage requirements by up to 50 to 80 percent. With a 2.8-12mm motorised varifocal lens, this camera offers great flexibility.
