Technical Specifications

Hikvision DS-7716NXI-K4 16-Channel 1.5U K Series AcuSense 4K NVR

The Hikvision DS-7716NXI-K4 is a 16-channel network video recorder designed for surveillance systems that need high-resolution recording, intelligent event filtering, substantial storage capacity, and centralized camera management. With support for cameras up to 12 MP, 160 Mbps incoming bandwidth, AcuSense human and vehicle recognition, facial recognition capabilities, and four SATA hard-drive bays, it provides a strong foundation for larger residential and commercial IP surveillance systems.

Advanced Motion Detection 2.0 and perimeter-protection analytics help distinguish people and vehicles from other movement, reducing unnecessary alarm events and making recorded footage easier to review. Independent HDMI and VGA outputs, 16-channel synchronous playback, H.265+ compression, dual Gigabit Ethernet interfaces, and Hik-Connect support provide flexibility for both local and remote system management.
