The Hikvision DS-7716NXI-K4 (C) is a 16-channel 1.5U AcuSense 4K network video recorder (NVR) designed for advanced surveillance systems that require intelligent analytics and high storage capacity. It supports up to 16 IP camera inputs, delivering high-resolution recording of up to 12 MP, along with 4K HDMI output for clear live viewing and playback. The system is built to handle demanding environments such as commercial buildings, industrial sites, and large-scale security installations.  Powered by AcuSense deep learning technology, the NVR can accurately differentiate between human and vehicle targets, significantly reducing false alarms caused by irrelevant motion. It also supports facial recognition, perimeter protection, and Motion Detection 2.0, improving event detection and search efficiency. These intelligent features help enhance overall security monitoring while reducing manual effort.  The device utilizes H.265+ compression technology, which optimizes bandwidth and reduces storage requirements without compromising video quality. With an incoming bandwidth of up to 160 Mbps, it ensures smooth performance even in multi-camera setups. It includes four SATA interfaces supporting up to 10–16 TB per hard drive, allowing large storage capacity for long-term recording.  Designed in a 1.5U rack-mountable chassis, the DS-7716NXI-K4 features dual Gigabit network interfaces, HDMI and VGA outputs, and multiple USB ports for flexible connectivity. With its powerful analytics, scalable storage, and reliable performance, it provides a robust solution for modern IP-based surveillance systems.
