How do the imaging specs compare?
The QNF-9010 uses a 1/2.3-inch 12MP CMOS sensor with a 1.08 mm f/2.2 lens, delivering a 187° horizontal and vertical field of view and a native resolution of 3008×3008 pixels. Its minimum color illumination is rated at 0.39 lux, and it provides 120 dB WDR via Hanwha's SSDR/BLC processing. DORI detection reach is 34.9 m, with identification at 3.5 m.
The WV-S4176A pairs an approximately 1/2-inch 12MP CMOS sensor with a 1.4 mm f/1.9 lens, covering 183° horizontally and vertically at a fisheye resolution of 2992×2992 pixels. Its wider aperture (f/1.9 vs. f/2.2) and lower minimum illumination—0.3 lux color / 0.2 lux black-and-white—give it a measurable low-light advantage. WDR is rated at up to 84 dB. DORI detection reach is 29.9 m, shorter than the QNF-9010, with identification at 3.0 m. The QNF-9010's longer DORI distances reflect the wider FOV and higher pixel-per-degree density despite the smaller sensor.
What about installation and environment?
The QNF-9010 is rated IP42, weighs 370 g, and measures Ø99×49 mm. It operates from −10°C to +40°C and draws a maximum of 7.7 W via IEEE 802.3af PoE Class 3. No IK impact rating is published in the provided specs. It also provides a CVBS composite video output (720×480/576) for installation-time alignment without a laptop. DC 12V input is not listed as an option.
The WV-S4176A is larger at Ø150×49.5 mm and heavier at approximately 420 g. It operates to a higher maximum temperature of +50°C, which may matter in warm equipment rooms. It accepts both IEEE 802.3af PoE (Class 0) and DC 12V at 680 mA, providing a redundant power path. No IP or IK ratings are stated in the provided specifications. A ±5° fixing-angle adjustment is built in.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles S, G, and T. The WV-S4176A additionally supports ONVIF Profile M, which covers metadata streaming for AI-tagged objects—relevant for VMS platforms that consume standardized analytics metadata. The QNF-9010 supports Hanwha's SUNAPI and the Wisenet open platform alongside ONVIF, providing deeper integration with Wisenet VMS. The WV-S4176A supports up to 14 concurrent unicast streams; the QNF-9010 supports 6 unicast users plus multicast.
On-camera analytics differ significantly. The QNF-9010 offers people counting, heatmap, defocus detection, and tampering. The WV-S4176A adds AI-VMD, AI Privacy Guard, AI Scene Change Detection, and AI Sound Classification (gunshot, yell, vehicle horn, glass break), all executed on its Ambarella CV22 SoC. The WV-S4176A includes a built-in nondirectional microphone, a 3.5 mm audio output, and G.711/G.726 compression; the QNF-9010 does not specify audio capability. Edge storage on the QNF-9010 supports microSD/SDXC up to 256 GB explicitly; the WV-S4176A supports microSD but maximum capacity is not stated in the provided specs. The WV-S4176A also exposes three alarm I/O terminals plus one AUX output; the QNF-9010 does not list hardware I/O terminals.
Which should you choose: the QNF-9010 or the S4176A?
Our take: The WV-S4176A is the stronger choice when the deployment requires on-camera AI analytics, audio detection, alarm I/O terminals, or integration with a VMS that consumes ONVIF Profile M metadata. Its f/1.9 aperture and 0.2 lux black-and-white sensitivity outperform the QNF-9010's f/2.2 / 0.39 lux color minimum in dim environments, and its 50°C operating ceiling versus the QNF-9010's 40°C provides headroom in warmer spaces. The dual PoE/DC 12V power input adds installation flexibility. The QNF-9010 holds concrete advantages in WDR headroom (120 dB vs. 84 dB), DORI detection reach (34.9 m vs. 29.9 m), confirmed IP42 ingress protection, an explicit 256 GB edge-storage ceiling, a smaller footprint (Ø99 mm vs. Ø150 mm), and deeper native Wisenet VMS integration via SUNAPI. Choose the QNF-9010 for Wisenet-centric deployments with high-contrast lighting challenges; choose the WV-S4176A where AI sound classification, audio I/O, hardware alarm terminals, or ONVIF Profile M are required.

Choose the QNF-9010 for Wisenet-centric deployments with high-contrast lighting challenges; choose the WV-S4176A where AI sound classification, audio I/O, hardware alarm terminals, or ONVIF Profile M are required.
Is the QNF-9010 or WV-S4176A better for low-light performance?
Based on published specs, the WV-S4176A has the advantage: its aperture is f/1.9 versus f/2.2 on the QNF-9010, and its minimum illumination is rated at 0.3 lux color / 0.2 lux B&W versus 0.39 lux color (color only specified) for the QNF-9010. Neither camera includes IR illumination, so both depend entirely on ambient light.
Which camera offers better on-camera analytics?
The WV-S4176A offers a broader AI analytics suite powered by its Ambarella CV22 SoC, including AI-VMD, AI People Counting, AI Privacy Guard, AI Scene Change Detection, and AI Sound Classification (gunshot, yell, vehicle horn, glass break). The QNF-9010 provides people counting, heatmap, defocus detection, and tampering detection but does not include sound classification or a published AI-processing chip specification.
Can either camera be used with third-party VMS platforms?
Yes. Both cameras support ONVIF Profiles S, G, and T, which cover live streaming, recording, and PTZ/analytics metadata and are accepted by most major VMS platforms. The WV-S4176A additionally supports ONVIF Profile M for standardized AI metadata streaming. The QNF-9010 also supports Hanwha's proprietary SUNAPI for deeper integration with Wisenet VMS.
