Hikvision DS-7716NXI-K4(D)/ALARM16+9 16-Channel AcuSense NVR with 4K Output and eSATA

For surveillance systems that demand intelligent event detection without compromising on storage flexibility, the Hikvision DS-7716NXI-K4(D)/ALARM16+9 stands apart from conventional NVRs. This 16-channel recorder integrates AcuSense technology to filter false alarms by distinguishing humans and vehicles from other moving objects, while its four SATA bays and eSATA port offer extensive storage expansion. Ideal for small to medium businesses, retail environments, and residential complexes where precise motion alerts and reliable recording are critical.

Highlights

• 16 independent IP camera channels with up to 12 MP recording resolution
• AcuSense: 4-channel perimeter protection or 1-channel facial recognition for accurate event detection
• Dual network interfaces (2x RJ45 Gigabit) for flexible network segmentation
• 4 SATA interfaces supporting up to 10 TB per HDD, plus 1 eSATA for external storage
• Simultaneous HDMI (up to 4K) and VGA outputs for local monitoring
• 16 alarm inputs and 4 alarm outputs for integration with sensors and sirens
• H.265+ compression to reduce bandwidth and storage requirements

In daily use

The DS-7716NXI-K4(D) simplifies video management by focusing on what matters. AcuSense reduces the burden of constant monitoring; the NVR can trigger alerts only when a person or vehicle crosses a predefined line or enters a designated area, minimizing false alarms from shadows, animals, or rain. With an incoming bandwidth of 160 Mbps, it comfortably handles streams from multiple high-resolution cameras. Operators can view live feeds on a 4K monitor via HDMI while the VGA output serves a secondary display. The front USB 3.0 port enables quick video export for evidence sharing, and the dual Ethernet ports allow separating camera traffic from management traffic for enhanced security and performance.
