Hikvision 16-Channel AcuSense 4K Network Video Recorder

Description

Hikvision DS-7616NXI-K2 16-Channel AcuSense NVR for Non-PoE IP CCTV Systems

The Hikvision DS-7616NXI-K2 is a 16-channel network video recorder designed for IP surveillance systems where camera networking and power are handled separately from the recorder. It is particularly well suited to installations that already use a dedicated PoE switch or structured network infrastructure.

With up to 160 Mbps incoming bandwidth, recording support up to 12 MP, two SATA interfaces and Hikvision AcuSense analytics, it provides a practical platform for medium-sized CCTV systems that need centralised recording, intelligent event filtering and high-resolution monitoring.

Is This Right for You?

Choose the DS-7616NXI-K2 when you need up to 16 IP camera channels and already have, or plan to use, separate network switching and camera power.

• Suitable for homes, offices, retail sites, warehouses and other multi-camera IP CCTV installations.
• A good choice when cameras are distributed through existing PoE network switches rather than connected directly to the recorder.
• Supports Hikvision cameras as well as compatible ONVIF Profile S/G network cameras.
• If you specifically need 16 integrated PoE camera ports on the recorder, choose the DS-7616NXI-K2/16P instead.

Why Choose This Product?

• 16 IP camera channels: supports larger surveillance systems without requiring multiple recorders.
• AcuSense intelligence: Motion Detection 2.0 and supported human and vehicle classification can help reduce false alarms caused by irrelevant movement.
• High-resolution recording: accepts recording resolutions up to 12 MP for detailed evidence capture with suitably matched cameras.
• 160 Mbps incoming bandwidth: provides capacity for multiple high-resolution network camera streams.
• Dual-drive storage: two SATA interfaces support up to 10 TB per HDD, giving flexibility when choosing recording retention capacity.
• Efficient H.265+ compression: helps reduce storage and bandwidth requirements compared with conventional H.264 recording.
• Flexible monitoring: independent HDMI and VGA outputs allow separate display configurations, with HDMI supporting up to 4K resolution.

Before You Buy

• This is the non-PoE DS-7616NXI-K2. It does not provide built-in PoE camera ports. A suitable network switch and camera power arrangement are required.
• The recorder provides two SATA interfaces supporting up to 10 TB per HDD. Recording requires suitable HDD storage; confirm whether your chosen package includes any pre-installed drives.
• Power requirement is 12 V DC, 3.3 A.
• AcuSense processing capacity depends on the function being used. On-recorder perimeter protection supports up to 2 channels at 4 MP, while facial detection and analytics supports 1 channel at up to 8 MP.
• Camera-based analytics and other intelligent functions depend on the capabilities and configuration of the connected cameras.

Storage Guide – Choosing the Right Hard Drive

The amount of storage you need depends on the number of cameras, camera resolution, recording schedule, and how long you want to keep your footage.

Quick Reference

Suggested starting capacities for typical CCTV systems:

Number of Cameras	Suggested Drive Capacity
1–4 cameras	1TB–2TB
5–8 cameras	2TB–4TB
9–16 cameras	6TB–10TB
More than 16 cameras	Calculate your requirements

Choose a larger drive when recording continuously, using high-resolution cameras, or keeping footage for longer periods.

---

Consider More Storage If You:

• Record continuously, 24 hours a day
• Use 4MP, 6MP, or 8MP/4K cameras
• Need to retain footage for 30 days or longer
• Have busy areas with frequent movement
• Record audio together with video
• Plan to add more cameras later
