New S2 Generation · 16-Channel · 32 MP · 8K · 200 W PoE
16CH WizSense S2 NVR
The Dahua DHI-NVR5216-16HP-AI/ANZ-S2 is the new-generation 16-channel, 2-HDD WizSense network video recorder for Australia and New Zealand. It combines 32 MP camera support, 8K HDMI output, up to 448 Mbps bandwidth, 16 built-in PoE+ ports with a 200 W total PoE budget, and upgraded recorder-side AI in a full 1U chassis.
Compared with the previous DHI-NVR5216-16P-AI/ANZ, the S2 revision delivers higher throughput, twice the recorder-side face-detection and perimeter-protection capacity, twice the SMD Plus capacity, a larger face database, more PoE power and support for larger hard drives. It is designed for demanding commercial, industrial, retail and multi-site CCTV systems that need fast forensic search and room to grow.

More AI capacity for faster investigations
4-channel AcuPick by recorder
Use reference images to find matching people and vehicles quickly. Recorder-side AcuPick supports 4 channels, while camera-side AcuPick is available across all channels with compatible Dahua AI cameras.
4-channel face detection and recognition
Run face detection on 4 channels at up to 12 face images per second per channel, with up to 20 face databases and 30,000 stored face images.
8-channel perimeter protection
Recorder-side tripwire and intrusion analytics support 8 channels with 10 IVS rules per channel and human/vehicle filtering to reduce false alarms.
16-channel SMD Plus
Secondary human and motor-vehicle classification is available across all 16 channels by the recorder, improving motion-event accuracy in rain, foliage and changing light.
4-channel video metadata
Extract up to 22 attributes across people, motor vehicles and non-motor vehicles for structured forensic search.
Expanded camera-side intelligence
Compatible Dahua cameras can pass through face recognition, AcuPick, ANPR, people counting, PPE detection, smart-object detection, heat maps and smart-sound detection.
8K output, 448 Mbps bandwidth and 40 TB storage
Up to 32 MP per channel
Connect up to 16 IP cameras with resolutions from standard definition through 32 MP, including 24 MP, 16 MP, 12 MP, 8 MP, 6 MP, 5 MP and 4 MP.
Up to 448 Mbps
With AI disabled, incoming, recording and outgoing bandwidth each reach 448 Mbps. With AI enabled, each is rated at 200 Mbps.

Frequently asked questions
What is the main improvement over the old NVR5216-16P?
The S2 increases AI-off bandwidth from 384 to 448 Mbps, upgrades HDMI from 4K to 8K, raises recorder-side face detection from 2 to 4 channels, perimeter protection from 4 to 8 channels, SMD Plus from 8 to 16 channels, PoE capacity from 130 W to 200 W, and maximum disk size from 16 TB to 20 TB per bay.
Does AcuPick require Dahua AI cameras?
The recorder can run AcuPick on 4 channels itself. Compatible Dahua AcuPick cameras extend camera-side performance across all channels and provide the richest person and vehicle search attributes.
Can it power sixteen PoE cameras?
Yes, provided the combined load stays within 200 W and no individual port exceeds 25.5 W. Ports 1–8 also support Dahua ePoE.
What is the maximum internal storage?
Two SATA bays support up to 20 TB per drive, giving a stated maximum of 40 TB, subject to drive compatibility and environmental conditions.
Will it work with third-party cameras?
Yes. It supports ONVIF 25.06 Profiles T, S, G and M. Standard recording is broadly compatible; advanced Dahua AI features depend on compatible Dahua cameras.
Can I view it remotely?
Yes. The recorder supports P2P remote access and Dahua mobile viewing on iOS and Android.
