Dahua DHI-NVR4116HS-8P-4KS3 16-Channel Compact 4K NVR with 8 PoE Ports

Q: Who is this compact 16-channel NVR best suited for?

t is a practical choice for installers and property owners who need up to 16 cameras but only require eight direct PoE connections at the recorder. Its compact 260 × 232.5 × 47.6 mm chassis suits smaller equipment cabinets and space-limited installations.

Q: How can I connect 16 cameras when the recorder has only eight PoE ports?

Up to eight compatible cameras can connect directly to the built-in PoE ports. Additional IP cameras can join the recorder through an external network or PoE switch connected to the same LAN, up to the recorder’s 16-channel access limit.

Q: Does enabling AI change the recorder’s bandwidth or decoding capacity?

Yes. With recorder AI disabled, bandwidth reaches 160 Mbps incoming, 160 Mbps recording and 80 Mbps outgoing. When AI is enabled, those limits become 80 Mbps incoming, 80 Mbps recording and 60 Mbps outgoing. Decoding capacity also varies by resolution and AI mode.

Q: Which AI features work without relying on an AI camera?

The recorder itself provides four-channel SMD Plus for secondary human and motor-vehicle filtering. Functions such as perimeter protection, face detection and recognition, people counting, stereo analysis and heat maps require compatible cameras that perform those analytics.

A Compact Recorder for Expandable 16-Camera Systems

The Dahua DHI-NVR4116HS-8P-4KS3 is a compact 16-channel network video recorder designed for installers building space-efficient surveillance systems in homes, retail stores and small commercial properties. Eight integrated PoE ports simplify the first stage of installation by carrying power and video over the same Ethernet cables. The remaining channels can be added through an external network switch, allowing the system to expand without replacing the recorder.

Practical AI Filtering and High-Resolution Viewing

Four-channel SMD Plus by Recorder applies secondary filtering to human and motor-vehicle motion events, reducing alarms caused by leaves, rain and lighting changes. Compatible AI cameras can supply additional functions such as six-channel perimeter protection, face detection and recognition, people counting, stereo analysis and heat maps. These camera-side capabilities depend on the connected camera rather than being generated independently by the recorder.

Storage, Decoding and Installation Essentials

Up to 12 MP Camera Access: Supports high-resolution IP video with 160 Mbps incoming and recording bandwidth when recorder AI is disabled.
4K Local Display: The HDMI output reaches 3840 × 2160, while VGA supports up to 1920 × 1080 for flexible monitor setups.
One SATA Drive Bay: Accepts one surveillance HDD with a supported capacity of up to 20 TB; the hard drive is not specified as included.
Efficient PoE Deployment: Eight IEEE 802.3af/at ports share a 72 W budget, with a maximum output of 25.5 W on a single port.
