Hikvision DS-7716NXI-K4/16P(D) 16 Channel PoE 12MP Acusense NVR

Overview

The Hikvision DS-7716NXI-K4/16P(D) is a 16-channel K-Series AcuSense NVRHikvision AcuSense NVR Range 2026: Sizing Guide — the popular UK trade tier sitting between consumer-grade M-series storage NVRs and full DeepinMind iDS-M-X servers. It records H.265+ / H.265 / H.264+ / H.264 with H.265+ compression cutting storage by up to 75%. Recording resolution up to 32 MP per channel (12 MP commonly used with AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide cameras). DecodingWhat is Decoding Capability capacity with AI off: 2-ch @ 12 MP, 4-ch @ 8 MP, 8-ch @ 4 MP, or 16-ch @ 1080p simultaneously (30 fps).

Storage: 4 × hot-plug SATA HDD bays, each accepting drives up to 16 TB (raw capacity up to 64 TB). Incoming bandwidth 160 Mbps / outgoing bandwidth 160 Mbps. 16-channel synchronous playback. ANR (Automatic Network Replenishment) keeps recordings intact when network drops by syncing missing frames from the camera-side SD card once the connection is restored. Stream-over-TLS encryption protects recordings in transit.

This NVR is a hybrid AI platform — the heavy lifting (object classification, smart events) runs camera-side on Hikvision AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide / ColorVuHikvision AcuSense vs ColorVu: UK Installer Guide for 2026 cameras and is recorded transparently here. On the NVR itself you get partial on-device AI: 1-ch live video facial recognition or 4-ch face-picture comparison, 2-ch perimeter protection (line crossing, intrusion, region entrance/exit) by-device, and Motion Detection 2.0 across all channels (4 MP, or 8 MP with enhanced SVC). Plus 2-ch by-device video analysis for human / vehicle recognition reduces false alarms on perimeter alerts. Face-picture libraries: up to 16 libraries, 20,000 face pictures total (each ≤ 4 MB, total ≤ 1 GB). For higher AI channel counts and AcuSearch / AcuSeek natural-language search, see the iDS-M-X DeepinMind range (Wave 5a) or DS-9xxx NXI VPro AcuSeek range (Wave 5c).

Output: 1 × HDMI up to 4K (3840 × 2160) @ 30 Hz + 1 × VGA up to 1080p — HDMI/VGA independent output for dual-monitor walls. 1-channel audio output (RCA, 1 KΩ) + 1-channel two-way audio (RCA, 2.0 Vp-p). Network: 1 × RJ-45 10/100/1000 Mbps self-adaptive Gigabit Ethernet, plus the built-in 16-port PoE switch (≤ 200 W budget, IEEE 802.3 af/at). 16 alarm inputs + 9 alarm outputs for siren, strobe, panic-button and access-control integration. Power: 100-240 VAC, 50/60 Hz, max consumption ≤ 20 W (without HDD, PoE off). Chassis 445 × 400 × 75 mm (19-inch rack-mounted 1.5U), approx. 5.0 kg without HDD. Approvals: CE, FCC, IC, CB, KC, UL, RoHS, REACH, WEEE, RCM, UKCA, LOA, BIS.
