Hanwha QNP-6250 vs i-PRO S66300-Z3: Specification Comparison
Both the Hanwha QNP-6250 and the i-PRO WV-S66300-Z3 are 2MP outdoor PTZ dome cameras targeting professional security installations where pan-tilt-zoom coverage, weatherproofing, and network integration are required. They share the same resolution class and form factor, making them genuine cross-shop candidates for integrators evaluating mid-range PTZ platforms. The comparison covers imaging performance, environmental and power ratings, and VMS/analytics compatibility to help installers and IT buyers determine which unit best fits their project requirements.

How do the imaging specs compare?
Both cameras use a 1/2.8-inch CMOS sensor at 1920×1080 and deliver 60 fps. The QNP-6250 offers a 25x optical zoom (4.44–111 mm, F1.6–F3.9) with a digital 32x extender for a combined 800x total, while the S66300-Z3 provides 32x optical zoom (4.25–136 mm, F1.6–F4.4) and extends to 48x at 1280×720 resolution. At tele end, the S66300-Z3 reaches a longer focal length (136 mm vs 111 mm), yielding a meaningfully greater DORI detection range: 1,833 m vs 1,471 m. The QNP-6250 carries a minimum illumination of 0.05 lux color / 0.005 lux B/W with built-in IR; the S66300-Z3 specifies 0.006 lux (the spec sheet does not separately list color vs B/W minimums or IR illumination distance beyond the 3.0 m focus-range note).
WDR tells a similar story: the QNP-6250 is rated at 120 dB, while the S66300-Z3 claims up to 144 dB (Super Dynamic On, Level 31 — a software-assisted figure). Both support ICR day/night switching and digital image stabilization via a built-in gyro sensor. Preset pan speed is identical at 700°/s on both; however, manual pan tops out at 200°/s on the QNP-6250 versus 150°/s on the S66300-Z3, and preset tilt speed is 300°/s on the QNP-6250 versus 500°/s on the S66300-Z3. The S66300-Z3 supports tilt from –20° to +90° (including upward-looking), whereas the QNP-6250 tilts 105° (90° to –15°), which is relevant for elevated or ceiling-center mounting scenarios.
What about installation and environment?
Both cameras are IP66-rated and dome-form-factor units intended for outdoor use. The S66300-Z3 adds NEMA 4X and IK10 impact resistance (per IEC 62262) and specifies wind resistance up to 40 m/s (~89 mph) — none of these ratings appear in the QNP-6250 spec sheet. The S66300-Z3's aluminum die-cast and polycarbonate dome construction contrasts with the QNP-6250's plastic housing. Operating temperature range is a significant differentiator: the S66300-Z3 is rated –50°C to +60°C, whereas the QNP-6250 is rated –10°C to +55°C — a 40°C cold-side advantage for arctic or extreme-winter deployments.
Power requirements differ substantially. The QNP-6250 runs on PoE+ (IEEE 802.3at, Class 4, max 14.5 W typical 12 W), which is supported by the vast majority of installed PoE switches. The S66300-Z3 requires PoE++ (37.8 W), corresponding to PoE Class 6 — this mandates a PoE++ capable switch or injector, which adds infrastructure cost and planning. The QNP-6250 dimensions are ø152×218 mm at 1,700 g (3.75 lb); the S66300-Z3 is ø167×205 mm at approximately 3 kg (6.6 lb) — meaningfully heavier, which affects pendant and parapet mount load ratings.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profile S/G/T and H.265/H.264/MJPEG compression with CBR/VBR bitrate control and microSD edge storage. The QNP-6250 additionally supports ONVIF Profile G explicitly in its protocol list and Hanwha's SUNAPI/Wisenet open platform for deep integration with Wisenet VMS. The S66300-Z3 lists ONVIF Profiles G/M/S/T (adding Profile M for metadata). Audio compression support differs: the QNP-6250 supports G.711 and G.726, while the S66300-Z3 adds AAC-LC at 64/96/128 kbps — relevant for intercom or audio-analytics workflows. The QNP-6250 specifies 4 alarm inputs / 2 outputs; the S66300-Z3 provides 3 alarm inputs / 1 output.
On analytics, the S66300-Z3 offers a notably broader on-camera AI suite running on an Ambarella CV25m SoC: AI Video Motion Detection, AI Face Detection, AI People Detection, AI Vehicle Detection, AI Non-Mask Detection, AI Occupancy Detection, AI Scene Change Detection, and AI Sound Classification (gunshot, yell, vehicle horn, glass break). The QNP-6250 provides directional detection, enter/exit, virtual line, tampering, audio detection, and motion detection via its WiseStream II analytics — capable but less granular on AI classification. Security posture also differs: the S66300-Z3 is FIPS 140-2 Level 3 certified; no equivalent FIPS rating is listed for the QNP-6250. Concurrent user limits are 14 (S66300-Z3) versus 20 unicast users (QNP-6250).
Which should you choose: the QNP-6250 or the S66300-Z3?
Our take: The QNP-6250 is the stronger choice when budget, PoE infrastructure, and Wisenet VMS ecosystem alignment are the primary constraints. It draws only PoE+ (max 14.5 W vs 37.8 W), is lighter at 1,700 g vs ~3,000 g, connects to far more installed switches without upgrade, and carries a 3-year warranty at a lower typical street price. However, the S66300-Z3 holds concrete advantages in three spec areas that matter for demanding outdoor deployments: a wider operating temperature range (–50°C to +60°C vs –10°C to +55°C), greater mechanical protection (IK10 + NEMA 4X + aluminum die-cast vs no IK rating, plastic housing), and a richer AI analytics stack (face, people, vehicle, non-mask, sound classification, FIPS 140-2 L3) on its Ambarella CV25m SoC. Specifiers in northern climates, high-vandalism sites, or projects requiring classified-network-grade cybersecurity certification should weight the S66300-Z3 accordingly, provided PoE++ switching infrastructure is in scope.

Frequently Asked Questions
Which should you choose: the QNP-6250 or the S66300-Z3?
The QNP-6250 is the stronger choice when budget, PoE infrastructure, and Wisenet VMS ecosystem alignment are the primary constraints. It draws only PoE+ (max 14.5 W vs 37.8 W), is lighter at 1,700 g vs ~3,000 g, connects to far more installed switches without upgrade, and carries a 3-year warranty at a lower typical street price. However, the S66300-Z3 holds concrete advantages in three spec areas that matter for demanding outdoor deployments: a wider operating temperature range (–50°C to +60°C vs –10°C to +55°C), greater mechanical protection (IK10 + NEMA 4X + aluminum die-cast vs no IK rating, plastic housing), and a richer AI analytics stack (face, people, vehicle, non-mask, sound classification, FIPS 140-2 L3) on its Ambarella CV25m SoC. Specifiers in northern climates, high-vandalism sites, or projects requiring classified-network-grade cybersecurity certification should weight the S66300-Z3 accordingly, provided PoE++ switching infrastructure is in scope.
Is the QNP-6250 or WV-S66300-Z3 better for low-light performance?
Based on the provided specs, the QNP-6250 lists 0.05 lux color / 0.005 lux B/W minimum illumination with built-in IR. The S66300-Z3 lists 0.006 lux without separately specifying color vs B/W minimums; its spec sheet does not list an IR illumination throw distance beyond a 3.0 m minimum focus range note. The QNP-6250's 0.005 lux B/W figure suggests strong IR-assisted low-light performance, but the S66300-Z3's 144 dB Super Dynamic WDR rating (vs 120 dB on the QNP-6250) gives it an advantage in high-contrast scenes such as entrances with bright backgrounds.
Can I power either camera from my existing PoE switch?
The QNP-6250 runs on standard PoE+ (IEEE 802.3at, Class 4, max 14.5 W), which is supported by the majority of enterprise and mid-market PoE switches installed today. The WV-S66300-Z3 requires PoE++ (Class 6, 37.8 W), which demands a PoE++ capable switch port or a dedicated injector. If your installed infrastructure is PoE+ only, the QNP-6250 drops in without a switch upgrade; the S66300-Z3 will require verifying or upgrading switch capacity.
Which camera is better suited for cold-weather or extreme outdoor environments?
The WV-S66300-Z3 is rated for operation from –50°C to +60°C, versus –10°C to +55°C for the QNP-6250 — a 40°C cold-side advantage. The S66300-Z3 also adds IK10 vandal resistance, NEMA 4X, aluminum die-cast construction, and a specified wind resistance of up to 40 m/s (~89 mph). None of these mechanical or extended-temperature ratings appear in the QNP-6250 spec sheet. For installations in harsh climates or exposed high-wind locations, the S66300-Z3's environmental specifications are substantially stronger.
