Hanwha QNF-9010 vs i-PRO S4576LA: Specification Comparison
Both the Hanwha QNF-9010 and the i-PRO WV-S4576LA are 12MP fixed fisheye IP cameras designed for panoramic surveillance, making them genuine cross-shop candidates for buyers evaluating single-sensor 360-degree coverage. The QNF-9010 is rated for indoor use, while the S4576LA is an outdoor-hardened dome. This comparison addresses imaging performance, environmental suitability, and integration fit to help installers and IT buyers determine which model aligns with their deployment requirements.

How do the imaging specs compare?
Both cameras share a 12MP resolution, but differ in sensor size and lens geometry. The QNF-9010 uses a 1/2.3-inch CMOS sensor with a 1.08mm fixed focal length and a 187° horizontal, vertical, and diagonal field of view, delivering up to 30fps at 3008×3008. Its minimum illumination is rated at 0.39 lux (color, F2.2). The S4576LA uses an approximately 1/2-inch CMOS sensor with a 1.4mm focal length and a 183° horizontal and vertical field of view, running at 25fps. Its minimum illumination is 0.3 lux color and 0.04 lux in black-and-white mode, with 14m IR LED range enabling 0-lux operation. The QNF-9010 has no specified IR range beyond a 0.5m minimum object distance note; its IR capability is listed as built-in but no usable throw distance is provided in the spec data.
Wide dynamic range differs significantly between the two models. The QNF-9010 specifies 120dB WDR with SSDR and BLC compensation. The S4576LA lists a maximum of 84dB WDR (at level 31 with WDR On), plus adaptive black stretch, BLC, fog compensation, and HLC. For scenes with extreme contrast, the QNF-9010's 120dB WDR specification represents a substantial numeric advantage. The QNF-9010 also offers WiseStream II smart codec and SSNR V noise reduction. The S4576LA uses an Ambarella CV22 SoC and GOP-based smart coding with Auto VIQS. Maximum aperture is F2.2 on the QNF-9010 versus F1.9 on the S4576LA, giving the S4576LA a slight optical light-gathering edge at the lens level.
What about installation and environment?
The QNF-9010 is rated IP42 (protected against solid objects greater than 1mm and water dripping vertically) and is specified for indoor use only, with an operating temperature range of -10°C to +40°C (+14°F to +104°F). It weighs 370g and measures Ø99×49mm. No IK impact rating or vandal resistance is stated in the provided specs. Power is via PoE IEEE 802.3af Class 3 with a maximum draw of 7.7W.
The S4576LA is rated IP66 and NEMA 4X (dust-tight and protected against powerful water jets), IK10 (50J impact resistance per IEC 62262), and carries EN50155-TX railway application certification. Its operating temperature range is -40°C to +50°C with IR on, or -40°C to +60°C with IR off, making it suitable for extreme outdoor environments. It includes an anti-condensation system (Rosahl element) and wind resistance rated to 40 m/s (approx. 89 mph). The S4576LA weighs approximately 880g (plate mount) or 1.3kg with bracket, and also accepts DC 12V in addition to PoE IEEE 802.3af. It additionally provides 3 alarm input terminals, 1 alarm output, and 1 AUX output — hardware I/O not specified on the QNF-9010.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profile S, G, and T, and both use H.265/H.264 with CBR/VBR bitrate control plus MJPEG. The QNF-9010 supports up to 6 simultaneous unicast users and 3 streaming profiles. The S4576LA supports up to 14 concurrent users. The QNF-9010 exposes SUNAPI (HTTP API) and the Wisenet open platform in addition to ONVIF. The S4576LA supports ONVIF Profiles G, M, S, and T — the additional Profile M covers metadata streaming, which the QNF-9010 does not list. Both support microSD edge storage; the QNF-9010 specifies up to 256GB via Micro SD/SDHC/SDXC.
On analytics, the QNF-9010 offers people counting, heatmap, defocus detection, motion detection (4 polygonal zones), and tampering detection. The S4576LA offers AI-VMD, AI people counting for 360-degree fisheye, AI privacy guard for 360-degree fisheye, AI scene change detection, audio detection, and AI sound classification (gunshot, yell, vehicle horn, glass break). The S4576LA includes a built-in microphone input and audio output (3.5mm stereo mini jack), with audio compression via G.726 and G.711 — the QNF-9010 does not list audio input or output in its specifications. Privacy masking is 6 rectangular zones on the QNF-9010 versus up to 8 zones on the S4576LA.
Which should you choose: the QNF-9010 or the S4576LA?
Our take: The S4576LA is the stronger choice when the deployment is outdoors, requires vandal resistance, or demands audio analytics and wider concurrent-user support. The S4576LA's IP66/NEMA 4X/IK10 rating, -40°C to +50°C operating range, and 14m IR throw make it the only viable option of the two for exterior or harsh-environment installations. It also edges out on low-light monochrome sensitivity (0.04 lux vs. 0.39 lux), supports up to 14 concurrent users versus the QNF-9010's 6, and adds AI sound classification and hardware alarm I/O absent from the QNF-9010. The QNF-9010 is the stronger choice for indoor deployments where WDR performance in high-contrast environments is the primary concern: its 120dB WDR specification exceeds the S4576LA's 84dB maximum. Choose the QNF-9010 for indoor retail or lobby applications with difficult lighting; choose the S4576LA for any outdoor, semi-outdoor, or high-security installation.

Frequently Asked Questions
Which should you choose: the QNF-9010 or the S4576LA?
The S4576LA is the stronger choice when the deployment is outdoors, requires vandal resistance, or demands audio analytics and wider concurrent-user support. The S4576LA's IP66/NEMA 4X/IK10 rating, -40°C to +50°C operating range, and 14m IR throw make it the only viable option of the two for exterior or harsh-environment installations. It also edges out on low-light monochrome sensitivity (0.04 lux vs. 0.39 lux), supports up to 14 concurrent users versus the QNF-9010's 6, and adds AI sound classification and hardware alarm I/O absent from the QNF-9010. The QNF-9010 is the stronger choice for indoor deployments where WDR performance in high-contrast environments is the primary concern: its 120dB WDR specification exceeds the S4576LA's 84dB maximum. Choose the QNF-9010 for indoor retail or lobby applications with difficult lighting; choose the S4576LA for any outdoor, semi-outdoor, or high-security installation.
Is the QNF-9010 or S4576LA better for low-light performance?
The S4576LA has a lower minimum illumination in both color (0.3 lux vs. 0.39 lux) and black-and-white (0.04 lux specified), and it includes a 14m IR LED for true 0-lux operation. The QNF-9010 lists built-in IR but provides no usable IR throw distance in its specifications. For nighttime or near-zero-light conditions, the S4576LA's specified IR range and 0.04 lux B&W sensitivity give it a clear advantage based on the provided specs.
Can either camera be used outdoors?
Only the S4576LA is rated for outdoor use. It carries IP66 and NEMA 4X water and dust resistance, IK10 impact resistance, an operating temperature range of -40°C to +50°C (IR on), and an anti-condensation system. The QNF-9010 is rated IP42 and specified for indoor use with an operating range of -10°C to +40°C; it is not suitable for exterior installation.
Which camera offers better WDR for high-contrast scenes like building entrances?
The QNF-9010 specifies 120dB WDR, compared to the S4576LA's maximum of 84dB (with WDR On at level 31). Based on the published specifications, the QNF-9010 has a significantly higher WDR rating, which is relevant for indoor scenes with mixed sunlight and shadow, such as lobbies or retail entrances with large windows.
